• Angle-closure glaucoma is glaucoma associated with a physically obstructed anterior chamber angle, which may be chronic or, rarely, acute. Symptoms of acute angle closure are severe ocular pain and redness, decreased vision, colored halos around lights, headache, nausea, and vomiting. Intraocular pressure (IOP) is elevated. Immediate...

• Angle-closure glaucoma (ACG) is a group of diseases in which there is reversible (appositional) or adhesional (synechial) closure of the anterior-chamber angle resulting in elevation of the intraocular pressure (IOP). The angle closure may occur in an acute or chronic form. In the acute form, the IOP rises rapidly as a result of...
