Atypical sarcoidosis-associated uveitis: diagnostic challenges.

Sarcoidosis is a multisystem disease of unknown aetiology with pulmonary involvement in most patients. Uveitis is common and often characteristic. We report a case of ocular sarcoidosis with grossly atypical contiguous optic neuropathy and choroiditis and describe the diagnostic challenges in this highly unusual presentation. High-dose systemic corticosteroid and immunosuppressive treatment was required for sustained control of intraocular inflammation.
