Retinal Conditions

Understanding the Retina
The retina is the specialized layer of tissue lining the back of our eye. Within the retina are millions of cells, which can be categorized into two different types: cones and rods. Each type has its own special function and they work together to help us see. Light rays are focused onto the retina (and the rods and cones) through our cornea, pupil and lens. The retina then converts these light rays into impulses that travel to our brain, where they are interpreted as the images we see. You could think of the retina as the film inside of a camera, though the retina is far more complex and has many blood vessels which supply oxygen and nutrients. A healthy, intact retina is needed for clear vision.
Due to the important role that the retina plays in our vision, retinal damage and disease can cause serious vision problems and even blindness. As with many areas of health, preventing problems from occurring is easier and often more successful than solving these issues after they develop.
