Best-corrected visual acuity was hand movement in right eye and 20\/20 in left eye. Funduscopy demonstrated diffuse retinal opacification and swelling at the posterior pole with a cherry red spot at the macula. There was sparing of the superonasal macula with a patent cilioretinal artery. OCT showed diffuse inner retinal thickening of the temporal macula. He was diagnosed as central retinal artery occlusion with cilioretinal sparing in right eye. He was a known case of Eisenmenger syndrome secondary to a large congenital ventricular septal defect. Medical history was notable for prominent pulmonary hypertension and shortness of breath on exertion. Physical examination revealed a harsh systolic murmur. Extremities showed digital erythema and severe clubbing. Chest X-ray demonstrated cardiomegaly.
