ACE and panuveitis: Panuveitis occurs in 6-33% of patients with sarcoidosis.[93–96] Presence of panuveitis is considered as a poor prognostic factor in patients with sarcoidosis.[93, 97, 98] The gold standard in the diagnosis of sarcoidosis is histopathological evidence of noncaseating granuloma.[99] The routine clinical tests for diagnosing sarcoid uveitis include Mantoux test, chest X-ray, serum angiotensin converting enzyme levels, erythrocyte sedimentation rate.
