Coexistent Optic Neuritis and Isolated Acute Sphenoid Sinusitis

Abstract

Abstract We report two cases of optic neuritis associated with isolated acute sphenoid sinusitis. This is the first report of isolated sphenoid sinusitis with dehiscent optic canal with exposed nerve presented with optic neuritis without any orbital inflammation. In both cases visual acuity deteriorated with steroid therapy, CT scan showed air fluid in the sphenoid sinus with dehiscent optic canal. Antibiotic, sphenoidotomy and later steroid course had a partial recovery in vision.
