Abstract

Purpose: The purpose of this study was to report the technical efficacy and convenience of panretinal photocoagulation for proliferative diabetic retinopathy using a slit lamp based monospot laser (532nm, Iridex Oculight) versus navigated laser (532nm, Navilas).

Methods: Case series of eyes with proliferative diabetic retinopathy were included. Each eye underwent panretinal photocoagulation: half superior retina with slit lamp laser and the other half inferior retina field with navigated laser during the same day. Grade 3 burns with a 300microns spot size were placed with both modalities. Laser parameters and laser burn spread were evaluated.

Results: Using pulse duration of 30ms in both lasers, slit lamp laser required an average power intensity of 745mW compared to an average of 400mW when using navigated laser. Average time required per sitting was 15minutes and 5 minutes for slit lamp and navigated laser respectively. Pain level was considerably less when using navigated laser. Images taken at 3 months after laser session showed similar spot spread in both laser modalities.

Conclusions: When using same short pulse duration, Navigated laser is convenient, less time consuming and less painful for the patient compared with slit lamp monospot laser modality.
