Potential of the Pentacam in Screening for Narrow Angles in Patients with Chronic Angle-Closure Glaucoma

Background: Chronic angle-closure glaucoma (CACG) is a visually destructive disease. Effective management of CACG requires identifying eyes with narrow angle.
 Objective: To compare pentacam gonioscopy in detecting angles CACG.
 Method: We enrolled 101 glaucoma. Gonioscopy was performed on all eyes. Using Shaffer’s grading, subjects were classified into angle closure and open angle. Anterior chamber volume (ACV) anterior depth (ACD) measured the pentacam. Receiver operating curve constructed for each parameter area under (AUC) calculated.
 Results: Ten (9.9%) as gonioscopy. detect angles, ACV (AUC 0.956; 95% confidence interval (CI) 0.894–0.987) similar to ACD (AUC=0.930, p=0.33). cutoff 102 mm3 , had 100% sensitivity 88.5% specificity patients. With an PPV 48.9% (95% CI, 34.8–68.2), while NPV (94.1– 100%), using 9.9% prevalence from this study.
 Conclusion: by have potential determine Keywords: glaucoma, Pentacam HR, volume,
