Glaucoma

Glaucoma is a type of eye disease that involves damage to the optic nerve.  This can result in vision loss and blindness if not treated. An increase in intraocular pressure is one of the biggest risk factors and indicators of glaucoma, and many of the treatments are aimed at lowering this pressure. Treatment options include eye drops that increase aqueous outflow, such as prostaglandins, alpha adrenergic agonists, and cholinergic agonists. There are also eye drops that decrease aqueous production, such as alpha adrenergic agonists, beta blockers, and carbonic anhydrase inhibitors.

Examples:

Prostaglandins: Latanoprost, bimatoprost, travoprost, tafluprost, unoprostone

Beta blockers: timolol, betaxolol, carteolol, levobunolol

Alpha adrenergic Agonists: brimonidine

Carbonic anhydrase inhibitors: brinzolamide, dorzolamide,
