Purpose: To investigate the effects of Pascal (Topcon Medical Laser Systems, Inc. Oakland, NJ) pan-retinal photocoagulation (PRP) on the optic nerve head (ONH). Method: This was a prospective case control study comparing 3 groups of patients seen in the diabetic retinopathy (DR) clinics, without any coexistent optic nerve pathology. Group A patients had proliferative or severe non proliferative DR necessitating PRP during the study period. Group B patients had mild or moderate DR and did not require PRP throughout the study period. Group C patients had standard retinal laser (green argon or frequency doubled YAG) PRP at least 2 years ago. All the 3 Groups had retinal oxygenation measurements and retinal vessel caliber readings by Oxymap T1(Oxymap, Reykjavik, Iceland), optic disc stereophotographs, high definition optical coherence tomography (HD-OCT) scans of the ONH by both Cirrus (C..
