Ocular Biometry as a Predictor of Anterior Chamber Angle Closure
摘要
Glaucoma, a leading cause of irreversible blindness, often goes undetected due to its asymptomatic nature. Early identification and classification of glaucoma, especially angle closure glaucoma, is crucial for timely intervention. In this study, we evaluated the potential of ocular biometry as a clinician-independent, quick, and noninvasive predictor of angle closure. A total of 204 eyes from 110 subjects with angle closure attending a glaucoma clinic and 109 eyes from 58 normal Indian subjects with open angles were included. The participants underwent gonioscopy and A-scan biometry (IOL Master 700) to measure axial length, anterior chamber depth, and lens thickness. Logistic regression analysis revealed that angle closure was significantly dependent on anterior chamber depth, yielding a promising ROC AUC value of 0.946. These findings suggest that ocular biometry can be a valuable tool for community-based screening tests, aiding in the early detection of angle closure glaucoma.
