Moghimi S, et al. - A comparative scrutiny was conducted of the change in anterior segment morphology after laser peripheral iridotomy (LPI), in acute primary angle closure (APAC) and their fellow eyes. It was observed that LPI caused a prominent anterior chamber angle widening and increased anterior chamber area, in APAC eyes and their fellow eyes. The APAC eyes revealed the following changes: The iris flattened, cACD deepened, and the lens shifted posteriorly after resolution of the attack. In the case of fellow eyes, the increase in ACA was primarily attributed to decreased iris curvature.
