Evaluation of Anterior Segment Changes

Following Laser Peripheral Iridotomy Using Pentacam Scheimpflug Imaging System in Eyes with Primary Angle Closure (PAC)

Primary angle-closure glaucoma (PACG) is a major form of glaucoma in Asia.1 It is a leading cause of blindness worldwide. 2 Laser peripheral iridotomy (LPI) is the standard firstline intervention in both acute and chronic forms3. It is successful in preventing recurrence of acute attacks and virtually eliminates the risk of an acute attack in the fellow eye4. Peripheral iridotomy eliminates pupillary block, allowing the convex iris to flatten and widening the anterior chamber angle (Figure 1). Such changes in anterior chamber angle morphology are difficult to assess. Gonioscopy is difficult to perform in a reproducible fashion, limiting the ability to quantify changes after LPI.
