Abstract

Purpose: To correlate, presence of angle dysgenesis on ASOCT (ADoA) and outcomes of SLT.

Methods: 45 eyes of 34 JOAG patients, with uncontrolled IOP to undergo SLT, were evaluated for presence of ADOA, which was defined as the absence of Schlemm’s Canal (SC) and/or presence of hyperreflective membrane (HM) over TM as identified on ASOCT. Successful reduction in IOP at 6 months follow-up post SLT was correlated with ADoA.

Results: 57.8% (26/45) eyes showed > 20% reduction in IOP at 6months. SC was identified as present in 100% of eyes with success vs 47.4% of eyes with failure (p < 0.001). HM was identified as present in none of the eyes with success vs 58% eyes with failure (p < 0.001). On regression analysis, the presence of SC increased the chances of SLT success by 12 times, and the absence of HM was associated with a 7.6 times greater chance of success. Conclusion: The presence of SC and absence of HM on ASOCT is a predictor for successful IOP reduction after SLT.
