Systemic Sarcoidosis Presenting as Bilateral Optic Neuritis

Abstract

Sarcoidosis is a multi-systemic inflammatory disease in which non-caseating granuloma occur in different sites producing variable clinical symptoms. Although it can involve various organs including brain and orbits, bilateral optic neuritis as the first symptom of systemic sarcoidosis is rare. Sarcoidosis is a diagnostic challenge, especially if systemic symptoms are absent. We report a patient who presented bilateral optic neuritis as the first manifestation of systemic sarcoidosis without other systemic symptoms including cranial neuropathies or intraocular involvement.
