Optical Coherence Tomography Findings in a Patient with Foster Kennedy Syndrome

Abstract

Introduction: The aim of this report is to describe the optical coherence tomography findings in a case of Foster Kennedy syndrome. Method: Case report. Results: A 35-year-old man presented with a one-month history of headache and gradually progressive blurred vision in the left eye. His best corrected visual acuity was 20/20 in the right eye and 20/40 in the left eye. Fundoscopy revealed a swollen disc in the right eye and a pale disc in the left eye. Optical coherence tomography showed diffuse asymmetrical thickening of the peripapillary retinal nerve fiber layer in both eyes. Magnetic resonance imaging of the brain revealed a meningioma in the left sphenoid wing with optic nerve compression and cavernous sinus invasion. One year after surgery, the patient's visual acuity had improved to 20/20 in both eyes and his visual field had returned to normal. Conclusions: Optical coherence tomography enables structural evaluation and can be used as an adjuvant tool for the early detection of a brain tumor involving the optic nerve.
