Visual function after pan-retinal photocoagulation: a survey

PW Russell, R Sekuler and C Fetkenhour

Thirty-five diabetic patients who had undergone pan-retinal photocoagulation were surveyed to determine the frequency and severity of visual difficulties they experience. Among the most frequent problems were difficulty adjusting to dim lighting, difficulty adjusting to bright lighting, and trouble in sorting dark colors. Judging distances, negotiating stairways, and avoiding obstacles were identified as having become more difficult since the laser treatment. According to a correlation analysis, the difficulties encountered in some important tasks, such as driving in the daytime, were highly related to visual acuity. However, many of the problems reported most frequently, and many of the problems whose frequency had increased the most since the laser therapy, were not related to acuity. Despite their many visual complaints, the patients expressed very positive attitudes toward the photocoagulation treatment.
