angle closure glaucoma

Angle closure glaucoma is a type of glaucoma characterized by the iris being pushed forward, blocking the outflow of aqueous humor. This blockage occurs in the anterior chamber angle, where the iris meets the eye's wall. When the iris covers the trabecular meshwork, the eye's drainage channels become obstructed, leading to a rapid increase in intraocular pressure.1

This condition can cause sudden, severe eye pain, headaches, nausea, vomiting, and blurred vision with halos around lights. Prompt treatment is crucial to lower the pressure and prevent permanent optic nerve damage and vision loss. While some acute attacks may resolve temporarily, surgical intervention is often necessary for a permanent solution.21
