Recurrent rhinogenic optic neuropathy with favorable steroid response

Abstract

Rhinogenic optic neuropathy (rhinogenic ON), which is optic nerve disease associated with adjacent paranasal sinus pathology, could represent severe vision loss with or without extraocular movement limitation. Medical treatment such as corticosteroid and antibiotics is regarded as less effective and prognosis of surgical treatment varies with incomplete visual recovery. Rhinogenic ON is usually monophasic and recurrence/relapse has rarely been reported. Here, the authors report a case patient with recurrent rhinogenic ON presented favorable steroid therapeutic response, therefore, initially misdiagnosed with retrobulbar optic neuritis and prevented relapse by endoscopic sinus surgery.
