Macular degeneration is condition in which the center of the inner lining of the eye, known as the macula area of the retina, suffers gradual thinning, atrophy, and in some cases, bleeding. This can result in loss of central vision, affecting your ability to read, drive, and see clearly straight ahead.
Diabetic retinopathy, a condition caused by diabetes, occurs when the blood vessels in the back of the eye change, leading to a significant loss of vision. It is one of the most frequent causes of retinal blindness in the world.
Retinal detachment is disorder of the eye in which the retina peels away from its underlying layer of support tissue. Initial detachment may be localized, but without rapid treatment the entire retina may detach, leading to vision loss and blindness. Retinal detachment is considered a medical emergency.
