Primary angle-closure glaucoma
MONDO:0001868An angle-closure glaucoma characterized by closure of the anterior chamber angle by an intrinsic defect such that aqueous outflow is blocked and the intraocular pressure becomes inappropriately elevated leading to optic nerve damage and visual field loss. Primary angle-closure glaucoma has symptom progressive peripheral vision loss, decreased vision, and pain, redness, and headache in acute cases. Primary angle closure glaucoma can be caused by anatomically narrow angle, defects in the trabecular meshwork, and iris abnormalities. Primary angle-closure glaucoma has a strong genetic component.

Glaucoma surgery showdown: new procedure may offer safer option
Disease control Recruiting nowThis study compares two surgical procedures for people with primary angle-closure glaucoma: Phaco-GSL (cataract surgery combined with a procedure to open the eye's drainage angle) and trabeculectomy (a standard glaucoma surgery that creates a new drainage pathway). Researchers wa…

New eye camera could catch blindness before it starts
Knowledge-focused Recruiting nowThis study tests a special camera that takes super-detailed pictures of the back of the eye (the retina). The goal is to see if this technology can find eye diseases earlier than standard methods. Up to 1,000 people aged 12 and older, with or without eye disease, will have their …

Scientists probe molecular secrets of glaucoma eye strain
Knowledge-focused Recruiting nowThis study looks at why some people with primary angle-closure glaucoma have loose eye lenses (zonular laxity). Researchers will compare molecules from 150 participants—those with and without this lens looseness, plus healthy controls—to find key differences. The goal is to bette…
