Intravenous Pulse Corticosteroid Therapy in Euthyroid Optic Neuropathy: A Case Report

Abstract

Herein, the authors report an unusual case of euthyroid optic neuropathy without previous history of endocrinopathy. Visual loss and limitation of extraocular movements developed rapidly in both eyes. An orbital magnetic resonance imaging (MRI) revealed bilateral apical crowding and extraocular muscle hypertrophy with tendon sparing. The restricted visual fields dramatically improved after intravenous pulse corticosteroid therapy. Early diagnosis of euthyroid optic neuropathy and prompt treatment with pulse therapy may result in a favourable visual outcome.
