Abstract
Purpose
To assess diagnostic performance of Cirrus Anterior Segment Optical Coherence Tomography (ASOCT) parameters to differentiate gonioscopic grades of narrow angles.
Methods
This prospective cross sectional study included 100 eyes with clinically diagnosed angle closure disease. Quantitative ASOCT parameters such as angle width, angle opening distance (AOD), trabecular iris space area (TISA) at scleral spur distances of 500 and 750µm were measured.Shaffer’s grading system was used to grade narrow angles. Area under the receiver operating characteristic curves (AUCs) were generated to assess diagnostic performance of these measurements to differentiate grades of narrow angles.
