What condition is characterized by an increase in aqueous humor production?

Open-angle glaucoma is characterized by an increase in aqueous humor production, leading to elevated intraocular pressure (IOP). In this condition, the trabecular meshwork, which is responsible for draining the aqueous humor, is not functioning optimally, allowing for a buildup of fluid. Excessive production of aqueous humor, combined with inadequate drainage, results in increased pressure within the eye, which can damage the optic nerve and lead to vision loss.

Recognizing this mechanism is crucial in understanding how open-angle glaucoma differs from other ocular conditions. Cataracts involve the clouding of the lens and are not related to aqueous humor production. Dry eye syndrome is characterized by insufficient tear production or poor tear quality, while retinal vein occlusion typically involves issues related to blood flow in the retina rather than the production of aqueous humor. This distinct characteristic of increased aqueous humor production is what primarily defines the pathophysiology of open-angle glaucoma.
