Superior Laser Peripheral Iridotomy Confers Greater Risk of Negative Dysphotopsias than Temporal Laser Peripheral Iridotomy

Laser peripheral iridotomy (LPI) is largely used as the first course of action to treat primary angle-closure (PAC). Previous literature has long been divided on the relationship between iridotomy position and dysphotopsia onset. The current study investigates whether there is a correlation between iridotomy position, temporal versus superior, and new onset post-operative dysphotopsia rates.
