Retina is the part of the eye which is in the back like film in a camera, if you think of the eye like a camera, the front there are some lenses and in the back is film part. The film part is called retina and the center of the retina is called macula. Retinal issues are common. Macular degeneration is the most common condition amongst senior citizens, about one in three will have macular degeneration. Many retinal diseases need to be treated in a timely manner. For example, if there is a retinal detachment and it’s not treated, the vision would be lost. People who have retinal problem, feel that everything is blurry and it depends on which part of retina get effected. With macular diseases central field of vision tends to be blurry and with retinal detachment, it is like a curtain that comes from one side and is slowly expands. There are a number of retinal conditions that are treated with surgery. They include retinal detachment, or when the macula, the center of the retina, is wrinkled. It’s called macular pucker. There are occasionally holes in the center of the vision called macular hole. And also patients with diabetes occasionally get bleeding in the eye or get retinal detachment that needs surgery. One of the common retinal procedures is retinal laser. Retinal laser is a very effective treatment for conditions such as diabetic retinopathy and also for retinal tears. Retina surgery usually is done in an out-patient basis. So patient usually come, for example, in the morning, get the surgery done and then leave the hospital by noon. One of the concerns about retinal procedure is pain. Fortunately, the level of pain is not significant. With some topical anesthetics such as eye drops, patients feel relatively comfortable a minute or two after the procedure. Yale Eye Center and Yale Medicine have been active in cutting-edge approach to retinal condition. We have participated in a large number of clinical trials that resulted in some of the new treatment for retinal diseases. I’m Ron Adelman, director of retinal and macular center at Yale Medicine.
