Ultrasound Biomicroscopic Diagnosis of Angle-closure Mechanisms in Vietnamese Subjects With Unilateral Angle-closure Glaucoma.

Objective: To identify the mechanisms of angle closure in the fellow eyes of Vietnamese subjects with unilateral primary angle-closure glaucoma (PACG) using ultrasound biomicroscopy (UBM) before and after prophylactic laser peripheral iridotomy (LPI).

Design: This is a prospective observational study.
