Based on Abad’s modified criteria, 17 patients had presumed sarcoid uveitis on the basis of either elevated ACE and positive chest CT (n = 11) or positive 18F-FDG PET suggestive of sarcoidosis (n = 4) and both positive chest CT and 18F-FDG PET (n = 2), while 9 patients had possible sarcoidosis (according to the American Thoracic Society guidelines) on the basis of isolated positive 18F-FDG PET (n = 7). Here, ACE is linked to sarcoidosis.
