Cataracts and Glaucoma are both conditions that cause the loss of vision. However, a cataract is the clouding of the eye’s lens over time, causing vision to become hazy, whereas, Glaucoma is a condition in which there is a buildup of pressure in the eyes that causes damage to the optic nerve that if not treated can result in irreversible blindness. Cataracts and Glaucoma can both be treated surgically and the outcomes are generally positive, however, in the case of Glaucoma, early diagnosis and treatment is necessary because the loss of vision cannot be reversed, as it can with cataract surgery.
