Objectives To investigate the characteristics and temporal changes in visual field defects (VFDs) eyes with acute central retinal artery occlusion (CRAO). Design Retrospective, observational case series Methods A total of 119 patients diagnosed non-arteritic CRAO through examination Goldmann perimetry were included among who visited Seoul National University Bundang Hospital between January 2009 December 2016. They treated either conservative treatments or intra-arterial thrombolysis (IAT). The baseline features results association clinical parameters including acuity, optical coherence tomography (OCT) findings, stages. Results All showed defect suffered unilateral CRAO. We observed five characteristic VFDs: peripheral constriction only (8%), paracentral scotoma (3%), cecocentral (19%), island (59%), no (10%). Severe VFDs associated severe stages, poor BCVA, delayed arterial perfusion, morphologic on OCT. found improvements 39% all cases during follow-up periods. Mild good mild changes, initial significantly improvement. Conclusions types their improvement are related to severity ischemia. suggest that underlying mechanisms involve balance perfusion ischemic vulnerability each area.
