Abstract

Purpose: To report a rare ophthalmic complication associated with Functional Endoscopic Sinus Surgery (FESS)
Methods: Descriptive case report
Results: A 25-year-old male presented with right eye diminution of vision associated with ophthalmoplegia and deviation of eye following FESS for deviated nasal septum. On examination, he had a large angle right exotropia with enophthalmos and restricted extra ocular movements. Pupils were dilated and fixed suggestive of optic neuropathy and fundus revealed a central retinal artery occlusion. Multimodal imaging revealed Optic nerve sheath hematoma, fracture of medial orbital wall and orbital floor along with medial rectus disinsertion. Due to delayed presentation at our clinic, he was managed conservatively with intravenous and oral corticosteroids with mild improvement in ocular movement and vision.
