Anatomy of the Eye Topic Guide
Anatomy and Physiology of the Eye: Even though the eye is small, only about 1 inch in diameter, it serves a very important function -- the sense of sight. Vision is by far the most used of the five senses and is one of the primary means that we use to gather information from our surroundings.
Glaucoma Glaucoma can be caused by a number of eye diseases that can damage the optic nerve, typically by elevating pressure inside the eye, which is called intraocular pressure (IOP) or ocular hypertension. Symptoms begin slowly and include vision loss and irregularities, eye pain, headache, nausea, and vomiting. Beta-blockers, Alpha-adrenergic agonists, and prostaglandin analogs are drugs used to treat glaucoma. Sometimes surgery is necessary, especially with congenital glaucoma. The disease is not curable, but can be managed.
