Blindness is the inability to see anything, even light. A completely blind person is unable to see at all, however blindness is often used as a relative term to indicate visual impairment. Common causes of blindness include diabetes, macular degeneration, traumatic injury, and infection of the cornea. Less common causes of blindness may include vitamin A deficiency, vascular disease of the optic nerve, or toxic agents such as methanol. Diabetic retinopathy is a diabetes complication that causes damage to the blood vessels in light sensitive tissue, resulting in vision problems and even blindness. This condition can develop in anyone who has type 1 or type 2 diabetes.
