Abstract

Purpose : The purpose of our study is to determine if the location of the temporal LPI versus superior LPI is associated with visual disturbances. We tested the hypothesis that there is no difference in visual disturbances when comparing temporal LPI versus superior LPI location. We performed a retrospective study to learn if a difference in the location of the LPI is associated with difference in visual disturbances.

Methods : Data from 2012 -2015 was collected from a private clinic in San Juan, Puerto Rico. A total of 37 patients with primary angle-closure glaucoma or primary angle-closure suspect were recruited in the study. Laser peripheral iridotomy was performed randomly on different a location, in each eye. Superior laser peripheral iridotomy was performed on 20 (54%) patients and temporal LPI on 17(46%) patients. Subsequently, each patient was contact by phone and asked about the presence of visual disturbances - floaters, double images, dysphotopsias and shadows.

Results : After the data was collected, two of the patients complained of floaters and five complained of dysphotopsia. None of the patients complained of shadows or diplopia.

Conclusions : According to our data visual disturbances are rare after laser peripheral iridotomy. No significant diference was found when comparing temporal LPI versus superior LPI location. Our study was limited by the small amount of patients and the retrospective design. Further larger scale, prospective, controlled studies are needed to prove if their is an association between the anatomical location of the LPI and the visual disturbances.

This is an abstract that was submitted for the 2016 ARVO Annual Meeting, held in Seattle, Wash., May 1-5, 2016.
