PURPOSE To investigate the prevalence of suggestive signs for ocular sarcoidosis proposed by the International Workshop on Ocular Sarcoidosis (IWOS) in patients with sarcoidosis-associated uveitis. METHODS A retrospective study included 53 patients (77% female), with uveitis, who were seen in the period of 2010-2013 at the University Eye Hospital Ljubljana, Slovenia. All patients had confirmed pulmonary sarcoidosis based on clinical presentation, imaging and lung biopsy according to the ATS/ERS criteria. The presence of the seven clinical signs, suggested by the IWOS was determined in 47 patients with sufficient clinical data. RESULTS Patients commonly exhibited bilaterality (79%), keratic precipitates/iris nodules (49%), and multiple chorioretinal peripheral lesions (36%). Three or more signs were observed in 40% (19/47) of patients or 79% (11/14) of patients with primary ocular involvement. CONCLUSIONS Results add to the validation of IWOS criteria and emphasize the high percentage of at least three suggestive for ocular sarcoidosis in patients with primary ocular involvement.
