Herein, we report the case of a patient who developed unilateral blindness secondary to traumatic optic neuropathy and central retinal\udartery occlusion (CRAO) after endoscopic sinus surgery (ESS). Visual acuity was no light perception in the right eye and 1.0 in the left\udeye. Antrerior segment was normal in both eyes. Fundoscopy revealed pallor white coloration of the macula with indistinct margins of\udthe optic disc in the right eye and normal in the left eye. Fundus fluorescein angiography demonstrated CRAO. Fracture lines of the\udorbital wall at the level of the anterior ethmoidal cells and pronounced deviated nasal septum were detected on computed tomography.\udHerniation of the medial and inferior rectus muscles with extraconal fat tissue was observed. In addition to the findings on computed\udtomography, magnetic resonance imaging of the orbita showed signal changes in the optic nerve and retrobulbar edema indicating\udtraumatic optic neuropathy. In order to prevent severe vision loss, the surgeon should repair deviated nasal septum before the ESS and\udmust pay serious attention during the operation. (Turk J Ophthalmol 2015; 45: 42-44
