LPI in temporal iris yields less linear dysphotopsia than in superior iris
Laser peripheral iridotomy performed in the temporal iris resulted in less linear dysphotopsia than in the superior iris, according to a study. “This is supported both by theoretical optics and the results of this clinical trial. It is likely that nasal placement would result in similar findings as temporal placement,” the study authors said. The prospective, randomized clinical trial included 338 eyes of 169 patients with primary angle closure glaucoma (PACG) or suspected PACG who underwent laser peripheral iridotomy (LPI) temporally in one eye and superiorly in the fellow eye.
