AIM: To evaluate the changes in the anterior segment parameters of the subjects with primary angle closure suspect (PACS) before and after laser iridotomy (LI) using the Pentacam and gonioscopy.
METHODS: Forty -eight eyes of 48 PACS were included. Anterior chamber angle (ACA), central anterior chamber depth (ACD), anterior chamber volume (ACV) and central corneal thickness (CCT) were recorded from the Pentacam before and one month after LI. ACA was graded according to Shaffer classification using Goldmann gonioscopy.
RESULTS: ACA increased significantly from 25.59 +/- 4.41 to 26.46 +/- 4.33 degrees (P=0.009) and ACV changed from 85.97 +/- 1:16.07mm(3) to 99.25 +/- 15.83mm(3) (P=0.000). The changes in ACD, CCT and intraocular pressure were non significant (P>0.05). Gonioscopy showed significant widening of the Shaffer angle in 4 quadrants (P<0.001).
CONCLUSION: Pentacam can serve as the objective instrument in assessing the efficacy of LI.
