A retina is the thin covering that covers the outer part of the eye and helps the retina to see.
It is also referred to as the optic nerve.
The retina is made up of millions of tiny nerve cells, which are arranged in rows and columns, and can sense light from an outside source.
A retina can be damaged by physical damage, trauma or disease.
But it is more than just a simple cover for the eyes, which can also be damaged and need replacement.
In the United States, the retina is insured by the Federal Eye Institute.
In many countries, there is a government-funded system of retinal rehabilitation and repair, but the United Kingdom has a separate system, called the Vision Care Program.
The National Institutes of Health, the U.S. government agency that funds the research, provides money to research and development for new technology.
The American Eye Institute, the nonprofit that runs the Vision Center in Washington, D.C., receives the majority of the federal research funding.
It receives about $5 million annually from the NIH.
It also receives some support from the U of T. It oversees the Vision Lab and other facilities at the Eye Institute that are used to study the effects of vision damage on vision.
The institute uses about 40,000 of its staff to help research on the retina, said Sarah Karpman, the institute’s associate director of science and technology.
Karpman said the institute uses its research to develop treatments and treatments that can help restore vision.
“We’re really interested in looking at the role that the retina plays in the brain and how it contributes to vision,” she said.
Karmachian and colleagues have been studying how vision affects people with chronic retinal diseases, including macular degeneration.
The researchers were particularly interested in what happens when people have damage to the retina and how that affects their visual function.
“The retina has an enormous impact on our ability to see and to recognize,” Karmachyan said.
“It also helps our ability for us to recognize faces and objects.
We’ve learned that our ability in our peripheral vision is really affected by what is happening in our retina.”
Karmasians team also has been studying the effects on vision of light-induced damage to neurons in the retina.
He said that work was done with mice and that a study in mice that is being completed has shown that the damage can cause changes in the neurons that control the function of the retina’s electrical circuitry.
The team is looking into ways to develop drugs that could be used to restore vision in people with severe visual problems.
The eye and retina are so connected, said Karmashian, that if they are damaged, the brain can’t communicate with one another, which would cause a loss of information.
“It’s like an invisible wall,” Karpashian said.
“There’s a lot of work going on, a lot more than we can see,” she added.
“I think it’s very important that we understand how these two systems work together and that we look for ways to repair the damage.”
Karpashians research on retinal repair is focused on two areas: restoring normal vision in humans, and studying the consequences of vision loss in animals.
The research was supported by the National Institutes for Health, Canadian Institutes of Agriculture, U.K. National Research Council and the National Institute on Deafness and Other Communication Disorders.
The research was published in the Journal of Neuroscience.
