Acute angle-closure glaucoma

Acute angle-closure glaucoma is an ophthalmic emergency affecting the anterior segment and optic nerve of the eye, most frequently occurring in individuals with anatomically shallow anterior chambers or hyperopia The condition develops when the peripheral iris mechanically apposes the trabecular meshwork—most often triggered by pupillary block—which abruptly obstructs aqueous humor outflow and causes a precipitous elevation in intraocular pressure This sudden pressure surge threatens rapid, irre...

Acute angle-closure glaucoma is an ophthalmic emergency affecting the anterior segment and optic nerve of the eye, most frequently occurring in individuals with anatomically shallow anterior chambers or hyperopia The condition develops when the peripheral iris mechanically apposes the trabecular meshwork—most often triggered by pupillary block—which abruptly obstructs aqueous humor outflow and causes a precipitous elevation in intraocular pressure

This sudden pressure surge threatens rapid, irreversible glaucomatous optic nerve damage and typically presents with severe ocular pain, profound visual impairment, corneal edema, a mid-dilated nonreactive pupil, conjunctival injection, headache, and associated nausea or vomiting
