[Diagnosis of ocular sarcoidosis by diagnostic criteria for systemic sarcoidosis].
OBJECTIVE
To evaluate the diagnostic criteria for systemic sarcoidosis in diagnosis of ocular sarcoidosis.


METHODS
Subjects were 105 ocular sarcoidosis suspects and 37 patients with other uveitis. We diagnosed ocular sarcoidosis suspects using the diagnostic criteria for systemic sarcoidosis proposed by the Japanese Committee for Diffuse Lung Diseases. The criteria included histological and clinical diagnosis, and the clinical diagnosis required 5 systemic tests: 1) tuberculin skin test, 2) serum gamma-globulin(gamma-gl), 3) serum angiotensin converting enzyme(ACE), 4) serum lysozyme, and 5) 67Ga scintigraphy. Three positive findings including either 1) or 3) fulfilled the clinical diagnosis.


RESULTS
Sixty-two patients were histologically and/or clinically diagnosed, and 43 patients remained undiagnosed. The histological and clinical diagnosis did not produce the same diagnostic yields. The sensitivity of ACE and gamma-gl was low. The percentage of patients showing increased lymphocytosis and/or CD 4/8 in bronchoalveolar lavage was similarly high in the diagnosed and undiagnosed, suggesting the presence of definitive ocular sarcoidosis in the undiagnosed.


CONCLUSIONS
The diagnostic criteria for systemic sarcoidosis yielded false negative results in diagnosing ocular sarcoidosis. The selection and combination of systemic tests for clinical diagnosis should be further studied.
