Optical coherence tomography angiography characterization of acute and late stage Purtscher retinopathy

Purpose:To report a case of Purtscher retinopathy imaged with optical coherence tomography angiography.Methods:Case-report. Left eye fundoscopic examination in a 21-year old male after a road traffic accident with chest compression revealed multiple peri-papillary cotton-wool spots and intra- and pre-retinal hemorrhages. A diagnosis of Purtscher retinopathy was assumed.Results:In both the superficial and deep retinal plexuses, acute stage optical coherence tomography angiography identified multiple irregular areas of capillary non-perfusion that extended beyond the clinically visible peri-papillary cotton-wool spots. At 5-month follow-up, despite the clearing of visible cotton-wool spots, there were still permanent areas of irregular capillary non-perfusion and inner retina atrophy. These sequelae, along with a decrease in the peri-papillary retinal nerve fiber layer thickness, were consistent with a suboptimal visual outcome and a dense inferior arcuate scotoma.Conclusion:Baseline and follow-up optical c...
