Increased aqueous humor production
WebOct 25, 2024 · Glaucoma is an increase in intraocular pressure caused by a buildup of aqueous humor, an eye fluid that nourishes and provides oxygen throughout the eye. The fluid drains out of the eye through the filtration angle located between the iris and cornea. An equal balance between the production and drainage of aqueous humor keeps intraocular ... WebHypotony can occur with either increased outflow of aqueous humor or, less often, reduced production of aqueous humor by the ciliary body. Increased outflow may occur via a …
