Reports On Artificial Retina Development

A press release from Argonne National Laboratory reports on an attempt to make an embeddable replacement artificial retina.

LOS ANGELES, Nov. 26, 2002 – Secretary of Energy Spencer Abraham toured the University of Southern California's ophthalmology laboratories at the Doheny Eye Institute and heard from the national research team that hopes to restore vision to millions of people with blindness caused by retinal disorders. As a result of recent breakthroughs in science and engineering technology, Abraham announced that DOE will commit $9 million over three years to augment artificial retina research, including support for a laboratory within the Doheny Eye Institute on the USC campus.

The DOE national labs, partnering with the University of Southern California and North Carolina State University, are designing a micro-electronic device that would be implanted in the eye on the surface of the retina. A microelectrode array would perform the function of normal photoreceptive cells.

You can find more about this recent announcement in this UPI article.

Optobionics cofounders Vincent Chow and Dr. Alan Chow have invented and already surgically implanted their Artificial Silicon Retina in some human test subjects. The seeing abilty it provides is still pretty crude. But its impressive there are actually people walking around using their device. From an ABC News report in May 2002 the results for some test subjects are described:

Two years ago, Chow put an artificial retina into Bennett's right eye. Before surgery she couldn't see a thing, but when the bandages came off, she was shocked.

She can now see light and shadow, which means she can slowly find her way around. Bennett still cannot see shapes. But is it better than what she had before?

"Oh Lord, yes, yes," Bennett said.

John Crocker, another of Chow's patients, was blind for more than 50 years. But right after his operation, he got a huge surprise.

"I was walking through the house," Crocker said. "And I stopped and I looked and I could see the lights on our Christmas tree, which is the first time that's ever happened for a long time."

However, the Optobionics implant is providing more benefit than expected because its providing a source of stimulation that is somehow improving the functioning of the real retina:

What Dr. Chow found is that the chips also seem to be stimulating remaining healthy cells.

"We're pretty excited. We initially expected only some light perception where the implant was. What seems to be improvement outside the areas was unexpected," he said.


He said the device is having a "rescue effect" on the retina, restoring cells located near the implant site.

"What we think is happening is the implant is stimulating other cells around the retina. We're finding vision is improving not just where the implant is but also in areas near the implant," he said.

How the Optobionics ASR works:

The ASR™ microchip is a silicon chip 2mm in diameter and 25 microns thick, less than the thickness of a human hair. It contains approximately 5,000 microscopic solar cells called “microphotodiodes,” each with its own stimulating electrode. These microphotodiodes are designed to convert the light energy from images into electricalchemical impulses that stimulate the remaining functional cells of the retina in patients with AMD and RP types of conditions.

The ASR microchip is powered solely by incident light and does not require the use of external wires or batteries. When surgically implanted under the retina—in a location known as the “subretinal space”—the ASR chip is designed to produce visual signals similar to those produced by the photoreceptor layer. From their subretinal location, these artificial “photoelectric” signals from the ASR microchip are in a position to induce biological visual signals in the remaining functional retinal cells which may be processed and sent via the optic nerve to the brain.

Click thru to the previous link to see a picture of the ASR on a penny. Its quite small.

The Blindness Foundation is supporting a number of other groups which are also working on artificial retina development:

Several other research groups are working to develop an artificial retina. The Foundation currently supports two groups: Dr. Eugene de Juan and Mark Humayun of The Foundation’s Research Center at Johns Hopkins University, and Drs. Joseph Rizzo and John Wyatt, of Harvard Medical School and Massachusetts Institute of Technology, respectively. The Foundation also supports Dr. Richard Normann at the University of Utah, who is developing a silicon chip to be implanted in the visual cortex of the brain.

Obviously the first users for this sort of technology will be blind people. It will be a wonderful boon that will restore eyesight for millions of people. But what comes next? Once the resolution of an artificial retina can exceed that of a human eye (and that is a matter of when, not if) and it becomes possible to combine it with an artificial iris that has zoom capablity then suddenly artificial eye implants will become attractive for people with perfectly healthy eyes. If the future artificial retinas can be made from thin films that can shift their molecular configurations on-the-fly then it ought to be possible to even reconfigure (perhaps by straining eye muscles in some trained pattern) the retinas to look at different parts of the light spectrum as well. Imagine, for instance, soldiers or police shifting their eyesight into the infrared when on a dangerous nighttime operation. Or imagine just any person wanting to up their light sensitivity when outside at night or in a room with little available light.

Sufficiently advanced technologies developed to treat disease conditions will inevitably morph into technologies that will enhance function. Research on artificial implants for blindness is laying the groundwork for the eventual development of vastly superior artificially enhanced eyesight.

Update: Here are some details on the role that Lawrence Livermore National Laboratory plays in the DOE artificial retina projectp

Lawrence Livermore National Laboratory engineers are developing a microelectrode array for a multi-laboratory DOE project to construct an artificial retina or "epiretinal prosthesis."

LLNL's polymer-based microelectrode array.

The three-year DOE project brings together national labs, universities and a private company, with Oak Ridge serving as the lead laboratory.

An epiretinal prosthesis could restore vision to millions of people suffering from eye diseases such as retinitis pigmentosa, macular degeneration or those who are legally blind due to the loss of photoreceptor function. In many cases, the neural cells to which the photoreceptors are connected remain functional.

Project leader Dr. Mark Humayun, of the University of Southern California, has shown that electrical stimulation of the viable retinal cells can result in visual perception. These findings have sparked a worldwide effort to develop a retinal prosthesis device.

Expertise in biomedical microsystems at Lawrence Livermore's Center for Microtechnology is being tapped to develop a "flexible microelectrode array," able to conform to the curved shape of the retina, without damaging the delicate retinal tissue, and to integrate electronics developed by North Carolina State University. The device will serve as the interface between an electronic imaging system and the human eye, directly stimulating neurons via thin film conducting traces and electroplated electrodes.

"We're very excited to be a part of this collaboration," said Peter Krulevitch of the Lab's Center for Microtechnology and leader of the team developing the flexible microelectrode array. Other LLNL team members include LLNL employee and UC Davis graduate student Mariam Maghribi, fabrication technician Julie Hamilton, participating guest Dennis Polla, undergraduate summer student Armando Tovar from Trinity University, MIT graduate student Christina Park, engineer Courtney Davidson and scientist Tom Wilson.

Lab engineers have pioneered the use of poly(dimethylsiloxane), a form of silicone rubber simply called PDMS, in fabricating hybrid integrated microsystems for biomedical applications. In particular, the Lab has worked on "metalization" -- applying metals for electronics and electrodes to PDMS for implant devices.

"It's our important contribution to this project," Krulevitch said. "We've developed a technique for fabricating metal lines that can be stretched. This is really critical for a flexible device designed to conform to the shape of the retina."

The electronic array must be robust enough to withstand damage from the implant procedure and be biocompatible -- able to withstand the physiological conditions in the eye. Another reason for using PDMS is that silicone rubber is not only flexible, but is a promising material from a biocompatibility standpoint.

Humayun's group implanted three first-generation LLNL devices in a dog's eye to identify needed design and fabrication improvements. Livermore engineers are now working on a second-generation microelectrode array with smaller electrodes in greater numbers, and developing techniques to integrate the electrodes with electronics chips. The array's perimeter -- 4 mm across -- has been reinforced with micromolded ribs to facilitate handling and prevent curling or folding. The current version of the array is longer for short-term implant experiments. But the final device for implant will measure 4 mm by 4 mm.

Applications for the flexible electrode array go beyond the retinal prosthesis, according to Krulevitch, who says it has the potential to allow development of next-generation medical implant devices such as the "cochlear implant" for hearing. The technology could one day be used for "deep brain stimulation devices" for treating such diseases as Parkinson's, and spinal cord stimulation devices for treatment of chronic pain.


Partners in the project include Oak Ridge, Argonne, Sandia, Los Alamos, USC Doheny Eye Institute and North Carolina State University.

Hello, part of my University project we are looking into the investigation of biomedical products. Looking into biomedical products i became to have an interest in the microprocessing technology you are using to regain sight to patients. I was wondering if possible, could you send me a circuit & block diagram of your system which you design. This would help me to give me a feel if it has filters, processors and such forth.

My name is Madeline Maginn and I am 27 years old. I have lost my sight due to diabetic retinopathy for approximately 6 years now. I was very intrigued and excited when I heard about the research.
I would be greatful if you could forward me information.

Jeff Sierzega said at February 14, 2004 4:38 AM:

If Dr. Humuyan would care to look into my eyes I guarantee he would see something he has never seen before. The next generation of intraocular implants has been in use for some time now. They are fluidic, capable of motion, and look like black spots temporally located in the vitreous. They are light-emitting. If he would care to see for himself he can reach me at (503) 362-4301. I didn't invent these devices, or ask to have them installed, but they are there just the same. Sincerely, Jeff Sierzega

i have been diagnosed with high miopia. i currently have a giant retinal tear in my left eye and it is severely scarred with no vision. my eye muscle and lid is working perfectly. i had a retinal tear in my right eye and had surgery in 1998. they did a buckle procedure with the silicone fill. the silicone fill has been removed (1999). as of 2004, i am slowly losing my eyesight in my right eye. everything is getting brightly cloudy in my right eye. the left eye is very dark with no light vision. what is very unusual about my eyes is that i have elongated eyeballs. when they did the surgery for my right eye, it took 10ccs to fill after surgery, and even that wasn't quite enough to fill it. i would like to know if i'm a candidate for the artificial retina for my left eye. i live in Garden Grove, near USC. please reply back.

My daughter age 27 years old, residing in the Philippines, after two glaucoma operations had TEAR IN THE RETINA, and doctors said her eye nerves in the right eye have degenerated. Now she cannot see in the right eye. I hope God through a miracle would somehow cure her eye condition. It is also my hope and dream and plea to God and to everyone concerned that somehow technology would somehow come up with a working remedy for such a situation as her. As I remember, when I was young, this television was not even thinkable.

Mrs.Ruth Wicks said at June 7, 2004 5:18 PM:

My grand-daughter who is 18 years old was born 16 weeks premature and the oxygen used to save her life damaged the retinas of both eyes and she is totally blind.Could you let me know if the silicon implants could help her to obtain some sight.I realise that you would require more imformation on her condition I could obtain this if you require it.Hoping to hear from you soon.Regards Ruth Wicks.

deloris cannon said at September 27, 2004 7:08 PM:

My daughter was diagnosed with chronic uvetis when she was 14. She has had numerous surgeries on both retinas with no success. She is now 33 yers old and is totally blind. A few years ago we went to Johns Hopkins to see a doctor and was told the only thing that would help her would be a retina prothesis. Has there been any advancement in that area that might help her. also, are there any clinical trials that she could participate in as she would very much like to be considered for a candidate? Please respond. Thank you.

Leon said at February 18, 2005 12:07 PM:

He really wants to be one of the volunteers for further research.Please advise how to join the team. Very much appreciated if you can share the info.

Mike said at May 4, 2005 9:44 PM:

Hi, my name is mike. Approximately 1 year ago my right eye was severly scratched. Inflamation ensued, and within a day my vision gradually lapsed. It started to regain after a few months. Then it was discovered due to the scarring retinal detachment occured. My surgeon reattached the retina which he said was severly crumpled. Then within a few weeks, the bottom part of the retina is disattatching itself due to further scarring. I'm due for another surgery to try to seal that part of the retina again. Currently I have only about 5% vision in my right eye, I can only see some light coming through, barely any color at all and barely any shape. Will I be a good candidate for the artifical retina transplant? If so please email me at with information on how I can get involved with this procedure. Your help will be greatly appreciated.

There are many heartbreaking stories to be read here on this page and I am happy to know that the medical minded people in this world are here to feel a need to help those in need of their investigative minds. I too ask for help for my sister, one who would not ask for herself as she too is a professional care giver. She has been given plenty of reasons why she has almost completely lost the use of one of her eyes, none of which are ever given with a solution close at hand. I know that she has trouble thinking about her good eye getting more impaired through the years, and I feel awful that I cannot do anything for her. After reading information on this site today, I hope to receive more information as to which types of cases this proceedure can help with especially.

Thanking one et al.

I am writing on behalf of my friend Roudi, age 24, who is blind in both eyes since age 11 due to a mine explosion which occurred in Lebanon's civil war. His doctor from Wills Eye Institute describes his condition as "retinal detachment". Is there any new techonology or clinical trials being conducted (i.e.micro chip implants, camera's or transplants etc.) that address retinal detachment? I hope you can steer us to the right research, or medical teams. Thank you so much. We are praying for such miracle. Ann AMMAR

David Sklar said at October 3, 2005 9:25 AM:

My question is this: If the artificial retina can restore some level of vision in patients completely blinded by retinal diseases, what are the chances that this device could be very beneficial to those of us with milder vision loss? I have Startgardt's disease, a form of juvenille macular degeneration. My visual acuity measures between 20/100 and 20/200 (I can read the big E at the top of the standard eye chart). If the level of improvement depends on the chip's ability to stimulate healthy remaining cells in the retina, I would hope that this sort of technology could resstore a great deal of sight in those of us wih moderate vision loss.

My 27 years old son had a foreign body removal vitrectomy and now its 3months he CANNOT SEE AT ALL and his eye is still small/not formed, as per the following case summary may I kindly request your opinion - as to what can be done for my son to regain his vision in the left eye,(his right eye is completely fine):

On examination, his vision was 6/6, N6 in the right eye and 6/6p, N6 in the left eye. The intraocular pressure was 17mmHg in the right eye and 18mmHg in the left eye. Anterior segment examination was normal in both eyes. There were no signs of iridocyclitis in the left eye. The fundus of the right eye was normal. The left eye showed an intraocular foreign body in the inferior part of the vitreous cavity. It looked like a small piece of glass or acrylic and there was no vitritis or retinal edema. The patient was advised to come for regular follow-ups to monitor the left eye.

The patient came for followup examination on April 28, 2005. On examination, his vision was 6/6, N6 in the right eye and decreased to 6/24, N36 in the left eye. The intraocular pressure was 19mmHg in the right eye and 14mmHg in the left eye. Anterior segment was normal in the right eye. The left eye showed dense pigments on the lens with cataract and iridocyclitis. Fundus examination of the left eye showed an attached retina. The details could not be seen due to cataract. The B Scan of the left eye was done which showed an intra ocular foreign body.

The patient underwent vitrectomy + intraocular foreign body removal + phacoemulsification + fluid air exchange + cryopexy + C3F8 gas injection + scleral band under general anaesthesia on May 20, 2005. During surgery the intraocular foreign body was found to be impacted deep in the retina and chorid and there was a large choroidal haemorrage while removing the intraocular foreign body. The choroidal haemorrhage was removed during the surgery.

The patient came for a regular follow up. Post operatively there was mild hyphema and formation of cyclitic membrane for which he was treated with systemic and topical steroids. B Scan ultra sound of the left eye was done three weeks after surgery, which showed a dense vitreous haemorrhage and choroidal thichening and haemorrhage.

The patient underwent revitrectomy + silicon oil injection in the left eye under general anaesthesia on July 26, 2005. During surgery he was found to have a chorodial detachment with choroidal haemorrhage and severe proliferative vitreo retinopathy. The patient was put on systemic and topical steroids post operatively. There has been no recurrent choroidal or vitreous haemorrhage. However the choroidal detachment was still persistent on the last follow up.

The patient is advised to continue his medication and come for regular eye examinations.

My name is sharon and I'm inquiring about retinal surgery. My recent partner, 53 years old, sustained a serious injury over twenty years ago which eventually led to a detached retina. After three corrective surgerys spanning a couple of years, all to restore the detached retina,(the initial perforation was stiched and apparently healed), he gave up hope and eventually lost all sight in his left eye. I'm a medical intuitive and have been experiencing dreams about his sight restoration. These are occuring rather frequently, enough so that I feel compelled to pay attention to them. Any information I read re: retinal detatchment suggests nothing short of hopelessness, especially after such a long time...still the dreams come... awake or sleeping. I'm sensing a doctor with a rather thick accent who will offer hope in the form of a procedure that is barely tested, or very new. Perhaps this procedure is radical, but then the loss of sight is no less radical. What is the function of a michrochip? Are there other procedures currently being tested with sight loss of this duration due to retinal detachment? I thank you in advance for any help. Sincerely... sharon

About 2 years ago I was diagnosed with degenerative myopia. From what I understand and the research I have done, this is due to the retina being stretched very thin across my eye. Late last year I was diagnosed with glaucoma in my left eye. This is due to built up pressure on the optic nerve. I have lost some vision in my left eye. I read the article and was just blown away because, I sat down at my computer and decided to look up retinal replacement actually not expecting to find anything. Anyway, with such varied eye diseases do you think this would be something that could help me? Any information you could give me would be very much appreciated. Thank you!

Yes, you are a candidate to get an artificial retina eventually. The Doheny Eye Institute at USC in LA also is working on an artificial retina:

31 January 2006 Albuquerque, N.M., USA. A new research centre is to be established at the University of Illinois Urbana-Champaign to develop nanomedical devices based on cell ion transporters. The first project will be to develop bio-batteries for implantable devices, the first of which is an artificial retina developed at the University of Southern California.

A five-year, $6.5 million grant has been awarded by the National Eye Institute of the National Institutes of Health (NIH) to establish a new center, the National Center for Design of Biomimetic Nanoconductors. Based at the University of Illinois Urbana-Champaign under the direction of principal investigator Eric Jakobsson, the center is designed to rapidly launch revolutionary ideas in the use of nanomedicine.

The center will design, model, synthesize, and fabricate nanomedical devices based on natural and synthetic ion transporters — proteins that control ion motion across the membranes of living cells.

The first task for the center will be to design a class of devices for generating electric power — bio-batteries — for a wide array of implantable devices, starting with an artificial retina that has already been developed at the Doheny Eye Institute at the University of Southern California. The artificial retina and accompanying nanobattery will be used to correct certain types of macular degeneration.

I poked around the USC Doheny Eye Institute web site and found mention of who is doing the artificial retina research there:

A gift of $2.5 million from the Clarence and Estelle Albaugh Trust to provide medical equipment to the Keck School of Medicine will be used, in part, to assist Doheny researcher Dr. Mark Humayun and his team in creating an artificial retina that shows promise in restoring some measure of sight to the blind.


In conjunction with the ARVO meeting, the U.S. Department of Energy (DOE) held its second International Symposium on Artificial Vision. Dr. Mark Humayun and his team updated participants on the retinal implant that has been developed at Doheny and USC in partnership with Second Sight Medical Products, Inc., the DOE and the National Science Foundation. The researchers reported that all six blind patients who have tested the device thus far have been able to detect light, identify objects in their environment and even perceive motion after implantation with the device. While the device is currently being tested on patients with retinitis pigmentosa, it may eventually be used for millions of people with age-related macular degeneration (AMD).

So Humayun is working with a company called Second Sight Medical Products. That company is in Sylmar California. Check out this Google search on Second Sight Medical Products.

My son who is now 3yrs old is blind as a result of ROP. He has developed a secondary cataract in his left eye as well and has very poor light perception. ie. He can't tell the difference between day and night, but if the sun shines directly in his eyes he will turn his head away. He doesn't like the light in his face.

I wonder if he would be a candidate for the project, or if the visual centre of the brain will have shut down completely by now. I would like to register him as a test subject for one of the implants and would like to know how I can do this. We live in South Africa, but are desperate for anything that might help Georgie to see, even if its only shapes and shadows.

Please respond.

Thanks in advance.

Hello my daughter Abigayle is a 16 month old that has been completely blind since 8weeks old due to retina detachment. (Ischemic Retina Disease). She had a level 4 brain hemmorage and 3 small strokes at birth. She has been diagnosed with Cerebral Palsy. I heard about the retina replacement procedure at Arkansas Childrens Hospital in April of 2004. I would like to know if she is a candidate for the retina replacement surgery. As her father I would love for her to be able to see this beautiful world that the good Lord has givin us. I understand with her other problems she is not as high as a candidate as someone with no other problems, but being able to see would improve her quality of life. Her therapist say that the fact that she can not see makes her progress slower than others with the same disabilities. Please cantact me with information on how i may apply for her to be a participent in the research aspect of this wonderful new scientific discovery.
Thank you and God Bless

Dear Sir,
I had a retinal detachment in my left eye due to external injury 3-4 years ago. I have undergone silicon oil transplant surgery. The retina seems to have been successfully re-attached, but the vision is very less in my left eye with pot of haziness. I want to restore my vision and can please help me in this direction. I can provide any further details regarding my eye/vision etc.

Vision in my right eye is currently normal. Does retinal detachment, have any further effect on the right eye down the years. I am 28 years old.

He has had cornea transplants in the past but rejected them, could your product possibly work for him. If there is even the smallest chance of any improvement he would love the opportunity to take part in the research. Please let me know. Thank you kindly, Shea.

Dear Sirs,

My father (age 55) 4 months ago ,suffered from torn retina at three places in his left eye. After examining his doctor explained that his retinas are thin by inhertance and need to be operated for the scars top urgently. He had an operation in which after laser shots to strengthen other thin areas, silicon was implanted to heal the tornparts . But one month after this first operation a new torn formed in the same eye, in the vision center.

He had a second operation where the silicon was removed , the retina was again put edge to edge ( sorry for my incompetent explanation) and gas was applied in the eye bulb.

We still do not know how much of his vision could be saved, it will be more clear in the next 4 months because due to the gas applied to seal the retina , cataract is forming on this eye. And only after the cataract is removed we will see the result...

Now only 2 months of this second operation a new scar formed , this time unfortunately on his right eye and he will have an operation tomorrow.

It seems even if the torn part is healed the problem will most probably repeat because the retina is weaker. My question is could retinal transplantation be an option , a solution? Could you pls inform what are the limitations to be a transplantation candidate? Could you advise which hospitals/doctors are specified in this field?

Thanks in advance for all your help

Best Regards ,
Inci Salom ( )

Orval said at November 29, 2006 11:58 AM:

I am a police officer, 33 years old, married with 4 children. Shortly after returning from Iraq in July of 2004, I noticed some irregularities the far right peripheral vision of my right eye. My eye doctor made an initial diagnosis of Histoplasmosis. He found a lesion of abnormal blood vessels, which were not actively growing or leaking at the time. Within 6 months of that discovery, I was back at the eye doctor because of increased symptoms. It was discovered at that time that the blood vessels were growing and leaking again. I had thermal laser surgery done to stop the advance of the disease, which at that time was within 1.5 mm of the macula.

Fast forward to just the past week, when I made another appointment because of increased visual distortions. The vessel growth and leakage has now extended beyond the area of the laser surgery and is within 1 mm of the macula. My doctor has since changed my diagnosis to Serpiginous Choroiditis. This threatens to leave me blind in my right eye, which will, ultimately, cost me my career. I am 20/15 in my left eye, with some slight far-sighted tendencies, but have been rendered 20/30 to 20/40 in my right eye. My doctor advised 3 options. First was more laser surgery, which was sure to leave my vision worse than it currently is. Second was intra-ocular injection of one of 2 different drugs. The first drug was Lucentis, and the other started with an A, but I don't remember the name. Lucentis is FDA approved for my condition, and the other drug is not (but is FDA approved for other diseases). Lucentis costs over $2000 per application, with several required. The other drug costs $100 per application, with as little as one or two applications required. My doctor advised that there is a 95% chance of stopping the progression of the disease with either drug, and a 25 - 35% chance of reversing the damage already done. The third option was to let the disease progress, which will eventually result in total blindness in my right eye.

I chose the less expensive drug. I was not crazy about getting a shot in my eye, but so be it. I am not old enough for Medicare, so none of this is being covered despite my being double-insured. (Aren't insurance companies wonderful- they up the premiums and lower the benefits every year such that every raise I get, and then some, goes to them. Enjoy it, boys.....)

Given that I am a healthy and middle-aged (33) male, with the current state of technology and progress, do you believe it will become possible within my career (likely 25 more years ahead of me) to restore the vision in my right eye and preserve my career? I cannot read what I type on this page without getting extremely close to the screen (with my right eye). My left eye is so far unaffected.

Randall Parker said at November 29, 2006 5:50 PM:


Drugs to control blood vessel growth (anti-angiogenesis drugs) will greatly improve in coming years because they make excellent anti-cancer drugs.

Google on "Judah Folkman cancer" and you can read about the guy who pioneered this field at Harvard Medical School (he's in his 70s and still working). He laid the foundations that made possible the two drugs that you can take. He and his post-docs and grad students found most of the angiogenesis and anti-angiogenesis compounds so far found naturally occuring in the bdoy.

Given the huge money available for cancer treatments the development of anti-angiogenesis compounds is very well funded. I also expect we'll witness gene therapies that control angiogenesis. Gene therapy methods to turn off the genes that probably in your case are making too much of one of the angiogenesis compounds would probably stop your problem from getting worse.

Randall Parker said at November 29, 2006 6:17 PM:


As for full vision restoration: Part of the problem is blood vessel growth. But once that has been stopped other things probably will need repair. My guess is that, yes, at some point in the next 25 years all that damage will become repairable. But you need it to become repairable a lot sooner than, say, the last 5 years of your working career.

Time for you to become a supporter of gene therapy and stem cell therapy research. You don't have to become a supporter of human embryonic stem cell research. Scientists will develop ways to make stem cells jump through hoops without using cells from human embryos.

Since you now have a vested interest in the more rapid advancement of biomedical science and biotechnology a great place to start is by writing letters to your elected representatives in Washington DC (your House Rep, both Senators, and the President) asking for more funding and more rapid advancement of biomedical science in general and treatments such as stem cell therapies and gene therapies that'll help fix eyes in particular.

My mom had wet macula. She got laser treatment. After a few days She got a Lucentis injection which improved her vision. When she got the second Lucentis injection after a month, she got severe pain right away and the doctors gave her 70 antibiotic injections under hospital anaesthesia. She lost her vision completely. She has been told the injection was contaminated. It has been 3 months and now she can't even see the light. She has no movement.

Is there a cure still?
Can the ASR work for her?
What are the treatments for her under the circumstances?
This is very challenging in all respects for the whole family.

My mother lost vision due to retinal detachment. First, retina in her left eye was detached and the doctors could not reattach it. Then her right retina became detached and even though they reattached it, she was only able to differentiate day and night. That was few years ago, and now she also cannot see at all in her right eye. When she could see, she was very myopic, her best corrected vision in her left eye was 20/60 and in her right eye was maybe 20/100. It's been about 10 years since her first retina became detached. Is there any technology available to restore vision for blind people who lost their vision due to retina detachment?

My son is 4 and half years old and suffering from ROP STAGE-5 in both eyes. At 8 months age lensectomy and vitrectomy was performed in his right eye without much result. At present he does not have vision in any of his eyes but has some little light perception in his eyes. He is autistic also and his blindness is adding more to it. Please help me out in any possible solution to restore his vision in at least one of the eyes.

Please help! Can you do anything for severe eye trauma that involve ruptured globes(could not get all repaired because to posterior) My husband is in ICU at Shock Trauma in Baltimore MD and will recover from his injuries except the prognosis from the Ophthalmologists is grim. We will do anything possible in order for him to have some vision in at least one eye. Anything! Any experimental treatments or anything. Please give me some information or direction. PLEASE! If you don't deal with trauma, maybe you could direct me to someone that could help. Thanks

Just visited this site and saw the potential in your research. My friend had retina detachment in one of her eyes due to accident 20 years ago and lost vision. Her right eye is perfectly fine. Can this technology get her vision back?

I am a 43 year old mother of three. When I was 4 years old I asked my mom "why do I have two eyes"? Of course her response was to see. I then asked "why does only one work?" After that we went to the eye Dr. and was informed I was blind in my right eye due to a scar on my retina. I do not have a lazy eye and for the most part people can not notice. I walked late (19 mos.) am accident prone, and feel it all links to my vision and depth perception. Basically the only vision I have in my right eye is a blur of light if it is really bright, other than that is is all black or gray. I was not premature and was not given too much oxygen at birth (which I hear are the most common causes.) Does anyone have any information as to what other causes could be, or if any new technology may help me?

does it works will for this kind of eye disease

Rich said at March 27, 2014 9:52 AM:

My son is 19 and was born 3 months premature and developed ROP. He is totally blind in one eye and has 20/200 corrected vision in the other eye. The eye that he is totally blind in the retina is partially attached to keep the blood flowing to his eye. I was hoping that the chip could be used to give my son his sight.
