Outlook of Retina and Retinal Disorders

Submit Abstract Register Now

The retina acts like the film in a camera to create an image. When focused light strikes the retina, chemical reactions occur within specialized layers of cells. These chemical reactions cause electrical signals, which are transmitted through nerve cells into the optic nerve, which carries these signals to the brain, where the electrical signals are converted into recognizable images. Visual association areas of the brain further process the signals to make them understandable within the correct context.
