title: Odontogenic Sinusitis Resulting in Abscess Formation Within the Optic Chiasm and Tract: Case Report and Review.
abstract: A 33-year-old immunocompetent man developed rapid visual loss and a third nerve palsy secondary to acute rhinosinusitis and intracranial abscess formation. Despite endoscopic drainage of the ethmoid and sphenoid sinuses and empiric broad-spectrum antibiotics, the patient experienced progressive visual and neurological decline and ultimately required craniotomy for drainage of an optic apparatus abscess. Although odontogenic sinusitis rarely results in abscess formation of the visual pathways, early recognition and immediate treatment is imperative to decrease the risk of profound and permanent visual impairment.
