Management of Ophthalmic Complications Secondary to Functional Endoscopic Sinus Surgery

Abstract

Orbital complications of functional endoscopic sinus surgery (FESS) may cause irreversible damage to the orbital structures, including optic nerve, extraocular muscles, and lacrimal drainage system. The clinical diagnosis and management of these patients may be extremely difficult because of the complexity and severity of the injuries. We describe a patient with ocular motility disturbances, anisocoria, and optic neuropathy in the right eye secondary to FESS. Early medical and surgical intervention resulted in symptom resolution.
