Results were compared between pre and post laser treatment sessions in the study group and paired t-test was used for statistical analysis.Results: The P100 amplitude showed a significant difference among all treatment sessions with a decreasing trend in the study group after PRP (P<0.001). Also, P100 latency evaluation showed a significant increase after PRP in the study group in all post-PRP sessions (P<0.05). However, 1.5 months after laser treatment, an increase in amplitudes (P<0.001) and a decrease in latencies (P<0.001) of PRVEP were observed and the magnitudes of the parameters approximately returned to their baseline values.Conclusion: Although decreasing changes in the amplitude and increasing changes in the latency of PRVEP were observed after laser treatment in proliferative diabetic retinopathy patients, one and a half months after the completion of laser therapy, partial recovery of these parameters values was observed.Keywords: photocoagulation, visual evoked potential, proliferative diabetic retinopathyAmini Vishte RMirzajani AKhojasteh HDove Medical Pressarticlephotocoagulationvisual evoked potentialproliferative diabetic retinopathyOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 13, Pp 1635-1640 (2019)
