The retina is an area of light-sensitive tissue that lines the inner surface of the eye. When light hits the retina, it initiates a cascade of chemical and electrical events. These events trigger nerve impulses that the brain translates into the imagery we call our vision.
At Columbia, we have a team of physicians that are specially trained in addressing problems with the retina. In addition to our state-of-the art clinical work, we also benefit from a robust research environment. As an example, one of our recent clinical trials explored implanting electronic chips directly into the eye to digitally transform light waves into electrical signals. These signals can be fed into the brain through the optic nerve, a process that can provide a form of perceivable imagery for the blind.
