FDA approves telescope device for eyes
The U.S. Food and Drug Administration this week approved the first implantable miniature telescope for the eye, to treat macular degeneration. The device helps patients with end-stage, age-related macular degeneration, the leading cause of severe vision loss in Americans older than 60 After being placed into one eye, the device acts as a telescope by replacing the natural lens and magnifies and projects images onto a healthy portion of the retina, according to the FDA. The non-implanted eye is used for peripheral vision. Read the announcement here About 8 million people in the United States have macular degeneration, a condition that damages the center of the retina – called the macula - causing vision problems. For more on macular degeneration. The implantable miniature telescope is inserted in patients who are 75 years and older with severe to profound vision impairment. In clinical trials, 90 percent of the 219 subjects gained some visual acuity. But the treatment comes with risks, warned the FDA. It is a large device that can lead to cell loss in the cornea. The manufacturer, VisionCare Ophthalmic Technologies Inc., has agreed to include a detailed explanation of the risks associated with its implantation. The company must also follow up with the subjects for another two years and conduct a new study of 770 subjects to monitor adverse events for five years after implantation.

I wonder why they specify that it is for patients with age related macular degeneration only. I have a friend in her 30's who has severe macular degeneration due to type 1 diabetes. I had such hope when I first opened the article. Maybe it's a hint of what's to come... one can hope...
It is a test run used on people they decide are close to death anyway, and who will not suffer from further damage to their existing loss of vision.
I work on ARMD. The damaged area of the ARMD patient is much, much smaller than people with diabetic retinopathy. Also, ARMD is NOT an end-stage condition. People can live for decades after vision loss thru' this condition.
To add...hence, ARMD is easier to treat, and Diabetic retinopathy is much more complicated.
Unfortunately Jen, ARMD and diabetic retinopathy are two different beasts. Macular degeneration affects such a small area, and usually there is healthy tissue surrounding the damaged area that can be used in this case to help with magnification. Diabetic retinopathy usually damages the entire retina, leaving little to no healthy tissue to work with. Chances are your friend has had extensive laser surgery of the retina, which unfortunately damages tissue as well, but not to the extent that the diabetes does. I hope that one day your friend and many many others will be able to benefit from new research breakthroughs such as stem cells and possibly even retinal transplants.
How about doing somthing for kids affected by the juvenile form called Stargardts. I have a 13 year old son that was diagnosed at the age of 10, who has had to give up everything he loves!!
Why aren't we doing more to help those that have their whole lives ahead of them!

just because I have a weird sense of humor and work in the optical industry, look up Night Gallery, and eye transplant, it's an interesting episode
Why aren't there any eye transplants? It seem just about every other organ or limb can be restored by transplant.
Cornea transplants are the most common transplants (and mos successful) performed.
Because drs cannot reattach the optic nerve. Seems that currently stem cell research is the way to go.
Not yet.....you have to sever the optic nerve to remove the eyeball. Once the optic nerve is damaged you cant regain vision....optic nerve connects the eyeball to the brain
The eye is way to complex to transplant. Each eye has about 1,000,000 nerve fibers and you cannot reattach those. With other organs, you simply just re connect the blood vessels to make them work.
Oh, they can. Ever heard of a glass eye? You can't see with it, but it counts as a prosthetic.
I would like to know the same thing. I have two blind friends and they have artificial eyes, but do you think someday, or are they working on now to have eyes so the blind would be able to see??
can this be used for persons who has phthisis in the eye? (dead eye)
Brigitte, the retina is actually part of the brain. We are not even close to transplanting the entire eye because the neurons that are in the retina would somehow have to connect to other parts of the brain. This would be similar to repairing a severed spinal cord.
i wonder if in the near future, eye implants will be used as a remedy for advanced glaucoma.. or at least something other than teminal eye death
As an indireclty NIH-funded researcher, it is great to see such breakthroughs and the interest they generate. There are dozens of very intelligent people working on glaucoma, diabetic retinopathy and other severely blinding diseases. None of this would be done without decades of government-funded research. Please remember to support the National Eye Institute (NEI) branch of the NIH. Thx.
Super exciting development!
I would like to request an honest advise for Lipoma. I have many all over my body and used Mopical herbal which did not work.
Thought Tony might be interested in ths.
Cool! Bionic eyes! I want an x-ray set!
I'm a 33 year old female with Stargard's. How do I get more info on this new development and see about getting in line for one!
I have a 13 year old son that was diagnosed at the age of 10 with stargardts. Why aren't any of these trials being done for the young kids???
How can I get more information on this? My 90 yr. old Mother has severe Macular Degenration (wet) and has had 32 shots in each of her eyes. Maybe this could help her. Who can I contact? Thank you.
I wish you all a better world through the research our great and dedicated scientists conduct. Thank goodness Bush is gone who set us back a decade in progress.
great website

Get yourself a modest trial batch of the prospective coloration and fresh paint a rectangular yard (gauge) of wall from it. This really is a big enough region to enable you to assess precisely what the coloration is bound to appear to be.

The last question to answer when asking what is the best monocular for the bird hunter is whether or not you want one that can be fully detached from the camera or still attached. Detachable lenses are generally less expensive, but some can detach by themselves if they become accidentally dislodged.
