Optic Nerve Glioma Produces an Acute Loss of Vision

Abstract

A 17-Year-Old Girl Experienced An Acute Onset Of Visual Disturbance In The Left Eye And Retrobulbar Pain With Eye Movement. Ophthalmic Examination Showed Optic Disc Edema, An Enlarged Blind Spot, And A Swollen Optic Nerve. No Proptosis Was Noted. The Visual Acuity In Her Left Eye Responded Transiently To Treatment With Systemic Corticosteroids, But Decreased To No Light Perception 2'/2 Months After The Onset. Histopathologic Findings Of An Excised Section Of Optic Nerve Disclosed A Pilocytic Astrocytoma (Glioma) With Abundant Extracellular Mucopolysaccharides. This Case Represented An Unusual Condition In Which An Optic Nerve Glioma Simulated Optic Neuritis.
