Khojasteh H, Amini Vishte R, Mirzajani A, et al. - Researchers conducted this prospective cohort study to assess changes in electroretinogram (ERG) response over the course of multiple sessions of panretinal photocoagulation (PRP) in individuals with proliferative diabetic retinopathy (PDR). The sample consisted of 11 patients with PDR who required PRP. Participants in the study received three sessions of PRP separated by one-week intervals. ERG findings after PRP display reduced retinal function after each session which partially recovers by 6 weeks after therapy completion. Clinicians should be aware of such changes when preparing a course of treatment for PDR patients.
