AIM: To evaluate the effect of pan-retinal photocoagulation(PRP)on vision related quality of life and daily visual functioning in patients having proliferative diabetic retinopathy(PDR).

METHODS: Thirty patients(13 males, 17 females)with PDR and undergoing PRP were included in this study. Visual Function Questionnaire(VFQ-25)developed by the National Eye Institute(NEI)of America, was used to evaluate the vision-related quality of life and daily visual functioning before and after PRP. The VFQ-25 was filled in by the authors before and at 6mo after the completion of PRP in order to compare any changes in visual related quality of life and daily visual functioning. The pre and post treatment VFQ-25 scores were compared using paired t-test.

RESULTS: Mean VFQ-25 composite score before PRP was 74.79±15.7 and after PRP treatment it was 74.08±19.1(P=0.875). The difference between pre and post PRP VFQ-25 composite scores was not statistically significant.

CONCLUSION: PRP has no significant detrimental effect on vision related quality of life and daily visual functioning in patients having PDR.
