To the best of our knowledge this is the first report of high-resolution ocular coherence tomography findings in the healed form of photic post-cataract retinopathy. Case presentation A 76-year-old Caucasian man complained of paracentral scotoma persisting for six weeks after cataract surgery. Conclusion Ocular coherence tomography demonstrated a localized juxta-foveal area of retinal atrophy involving the photoreceptor layer and the retinal pigment epithelium layer. Introduction Operating microscope light-induced foveal damage is a well recognized occurrence following ocular surgery including complicated or lengthy cataract extraction and complex anterior segment procedures 1-5 . While the majority of injuries produce minimal symptoms scotoma and permanent central vision loss have occurred in some patients. Retinal edema is typically discernable a few days after exposure while prominent pigmentary changes of the fundus are not apparent prior to two to three weeks after exposure. The recent advent of high-definition ocular coherence computed tomography can help clinicians in analyzing the level and degree of retinal damage after photic damage induced by surgical microscope. Case presentation A healthy 76-year-old Caucasian man underwent phacoemulsification under retrobulbar anesthesia in his right eye with torn posterior capsule at the completion of cortex aspiration. Anterior vitrectomy was performed and a 5 X 6 mm intra-ocular lens was implanted in the sulcus. A coaxial illuminated microscope OPMI .
