Purpose
To determine whether laser peripheral iridotomy (LPI) location affects postoperative dysphotopsia symptoms.
Design
Multicenter, randomized, prospective, single-masked trial.
Participants
Five hundred fifty-nine South Indian patients 30 years of age or older diagnosed as primary angle-closure suspects (PACSs) or with primary angle closure (PAC) or primary angle-closure glaucoma (PACG) in both eyes.
Methods
Patients were randomized to either bilateral superior or bilateral nasal/temporal LPI. Occurrence of new visual disturbances was evaluated before and 2 weeks after LPI using a questionnaire based on the 7-item dysphotopsia symptoms described by Spaeth et al.
Main Outcome Measures
New-onset dysphotopsia symptoms.
