Abstract

Methods- In this prospective study, 120 eyes, with angle closure disease is included and categorized into three groups 1) Primary angle closure suspect- 53, 2) primary angle closure-28 and 3) primary angle closure glaucoma-26. Complete ophthalmic examination including gonioscopy, A-scan biometry, AS-OCT and PS-OCT was done. Based on AS-OCT images, 2 mechanisms of angle closure including, pupillary block & plateau iris was evaluated.

Results- There was a statistically significant difference in the mechanism of angle closure disease among the three groups (p<0.001) Although majority of the PACS and PAC had pupillary block mechanism (84.2% and 80% respectively), only 50% of PACG had dominant pupillary block mechanism. The percentage of plateau iris was highest in PACG eyes. Conclusions- Qualitative analysis of AS-OCT images remain a promising approach for detecting eyes at risk of angle closure. Pupillary block is the most common mechanism which leads to angle closure in PACD.
