## Overview

Glaucoma surgery is a type of eye surgery performed to treat glaucoma, a group of diseases which affect the optic nerve, resulting in vision loss. Glaucoma is characterized by increased intraocular pressure (IOP). Most glaucoma surgeries seek to lower IOP by facilitating the escape of excess aqueous humor from the eye, while others decrease the production of aqueous humor.
