What are treatments for blindness?
The treatment of visual impairment or blindness depends on the cause. In third-world nations where many people have poor vision as a result of a refractive error, merely prescribing and giving glasses will alleviate the problem. Nutritional causes of blindness can be addressed by dietary changes. There are millions of people in the world who are blind from cataracts. In these patients, cataract surgery would, in most cases, restore their sight. Inflammatory and infectious causes of blindness can be treated with medication in the form of drops or pills. Corneal transplantation may help people whose vision is absent as a result of corneal scarring.
