Editor,—Sarcoidosis, a multisystem granulomatous disease, involves the eye in approximately 25% to 50% of patients1 2 and produces numerous ocular findings.3 Definitive diagnosis requires a non-caseating granuloma in the absence of mycobacterial infection on biopsy. Although most patients have abnormal chest x rays, ocular sarcoidosis can precede pulmonary involvement, making diagnosis difficult. The following patient with ocular sarcoidosis—unresponsive to corticosteroids and cyclosporine—was diagnosed only after chorioretinal biopsy; she responded to azathioprine therapy.
