Cataract - A cataract is a clouding of the lens in the eye that affects vision.
Most cataracts are related to aging. Cataracts are very common in older
people. By age 80, more than half of all Americans either have a
cataract or have had cataract surgery. A cataract can occur in either or both eyes. It cannot spread from one eye to the other. (nei.gov)
Pinguecula - A pinguecula is a common, non-cancerous growth of the clear, thin tissue
(conjunctiva). The growth is raised slightly from the surface of
the white part of the eye (sclera).
POHS - a fungus causes scarring and inflammation of the retina. Central scarring can lead to loss of vision. (nih.gov)
Diabetic Retinopathy - Diabetic retinopathy is the most common diabetic eye disease and a
leading cause of blindness in American adults. It is caused by changes
in the blood vessels of the retina. In some people with diabetic retinopathy, blood vessels may swell and
leak fluid. In other people, abnormal new blood vessels grow on the
surface of the retina. If you have diabetic retinopathy, at first you may not notice changes
to your vision. But over time, diabetic retinopathy can get worse and
cause vision loss. Diabetic retinopathy usually affects both eyes. (nei.gov)
Hypertensive Retinopathy - Hypertensive retinopathy is damage to the retina from high blood pressure. (nih.gov)
