Metabolism is the process by which your body converts what you eat and drink into energy. During this complex biochemical process, calories in food and beverages are combined with oxygen to release the energy your body needs to function.
Closed-angle glaucoma is more common in women. Glaucoma has been called the silent thief of sight because the loss of vision usually occurs slowly over a long period of time. Worldwide, glaucoma is the second-leading cause of blindness after cataracts.
There are four main types of glaucoma: 1  chronic open-angle glaucoma â the most common type which often has few symptoms. 2  acute angle-closure glaucoma â which often has severe symptoms. 3  secondary glaucoma â caused by other conditions or eye treatments.  developmental glaucoma â a rare condition affecting young babies.
