What is glaucoma? What actually causes damage to the neurons and optic nerve with glaucoma?
Nobody is sure exactly “what glaucoma is” but at its most basic, glaucoma is gradual death of the optic nerve. If an attending asks you this question, say “knowbody knows” or “death of the optic nerve.” If you say “high pressure” you’ll be laughed at (glaucoma specialists are odd ducks). The optic nerve damage arises from pressure, stretching, sheer forces, vascular compromise, or some kind of hormone regulator – we’re not sure of the mechanism. 2. What is the flow-pathway for aqueous fluid? Where is it made, and where does it leave the eye? Aqueous is first produced by the ciliary body. It then flows forward through the pupil into the anterior chamber. Finally, aqueous drains through the trabecular meshwork and back into the venous system via the canal of Schlemm. 3. What’s the difference between open-angle and closed-angle glaucoma? How about chronic versus acute glaucoma? Open angle is a common, chronic condition where aqueous drainage is impaired. Closed-angle glaucoma is caused by
