Ultrasound biomicroscopy measured anterior and posterior chamber diameters--a novel way to evaluate angle-closure glaucoma.

Objective: To investigate anterior and posterior chamber diameters in primary angle-closure (PAC) and to correlate them to the angle opening parameters.

Material And Method: Fifty eyes of PAC and 45 age-matched controls underwent ultrasound biomicroscopy (UBM; model P60, Paradigm Medical Industries Inc., Salt Lake City, UT) scanning.
