SURGICAL: Intraocular Procedures Except Retina, Iris, and Lens

GG laucoma is an acute or chronic condition in which there is an increase of intraocular pressure (IOP), which leads to damage of the retina and optic nerve, with resulting visual field loss. In the normal eye, IOP (10 to 21 mm Hg) exists as long as there is a balance between the production, circulation, and outflow of aqueous humor. Aqueous humor is produced in the posterior chamber ciliary processes and flows through the pupil into the anterior chamber. From the anterior chamber, it passes through the canal of Schlemm and out through the aqueous veins into the anterior ciliary veins.

Increased IOP compromises blood flow to the optic nerve and retina. Tissue damage occurs as a result of the deficient blood supply and progresses from the periphery toward the fovea centralis. If IOP is left untreated, blindness results.
