Glaucoma: Overview

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Summary

Hypotony maculopathy after glaucoma surgery can cause vision loss and intraretinal cysts (IRC). Misdiagnosis as diabetic macular edema (DME) delayed treatment, leading to corneal decompensation and requiring a corneal transplant.

Hypotony maculopathy is a known complication of glaucoma filtering surgery.

It can lead to significant vision loss and presents with characteristic signs like choroidal folds and optic disc edema.

Optical coherence tomography (OCT) may reveal intraretinal cysts (IRC) as an atypical presentation.
