Flowchart of the specimen-selection procedure in this study. The specimens, which were taken from 30 eyes of patients with granulomatous uveitis that satisfied more than two items of seven intraocular clinical signs suggestive of ocular sarcoidosis, were classified according to the diagnostic criteria for sarcoidosis. Eleven patients did not meet the criteria and were classified into the sarcoid uveitis-suspected group. We used 16 eyes from these 11 patients for vitrectomy. Ten patients met the criteria and were classified into the sarcoidosis group. We used 14 eyes from these 10 patients for vitrectomy. To detect epithelioid granuloma/epithelioid cells, liquid-based cytology and the cell block procedure were performed on vitreous body specimens obtained by vitrectomy.
