Water Drinking Test in Patients With Occludable Angle

Completed · Not applicable

Conditions studied: Glaucoma

In brief

The water drinking test (WDT), is a predictive test that has been used to detect primary open angle glaucoma and recently has been demonstrated as a predictor of the diurnal tension curve. Clinically accurate provocative tests for asymptomatic eyes with shallow anterior chambers and narrow angles are highly desirable to detect patients prone to angle closure glaucoma. The aim of this pilot study is to evaluate the possible role of water drinking test in patients with narrow angles who are scheduled for prophylactic laser iridotomy.
