Visual side effects of successful scatter laser photocoagulation surgery for proliferative diabetic retinopathy: a literature review

Abstract

Purpose: To review the literature on limitations and adverse effects associated with scatter or panretinal laser photocoagulation (PRP) for diabetic retinopathy (DR).

Design: Literature review.

Results: Scatter laser photocoagulation is associated with moderate visual loss, some diminished visual field, reduced color vision, and reduced contrast sensitivity.

Conclusions: Scatter laser photocoagulation has been shown to reduce the risk of severe visual loss from proliferative DR. However, scatter treatment is associated with some decline in visual function. These effects should be studied more extensively and should be considered when comparing pharmacologic treatments for proliferative DR.
