Vision Loss after Endoscopic Sinus Surgery

A 41-year old Greek man with no significant medical history, apart from chronic rhinosinusitis underwent ESS for right paranasal sinus polyposis under general anaesthesia. No intraoperative complications were reported and the surgery was completed without any incident. The patient had no diabetes mellitus, hypertension nor any other systemic vascular disease. Immediately after recovering from the anaesthesia the patient complained for vision loss, reduced color perception, retrobulbar pain worsened on eye movement and total superior scotoma on his right eye. He was then referred to the Electrophysiology Department of Athens University and underwent a complete ophthalmological examination.

Although, and despite its continuous development over the past three decades complications may still occur.
