Abstract
The diagnosis of ocular sarcoid is presumptive in the absence of systemic disease. The association of elevated serum angiotensin-converting enzyme (ACE) levels with active systemic sarcoid has been well described. With a sensitive fluorimetric assay for ACE, we found that five of ten chronic granulomatous uveitis patients without systemic sarcoid had elevated serum ACE levels. None of ten patients with uveitis of known etiology had elevated serum ACE levels. We believe that the association of an elevated serum ACE level with chronic granulomatous uveitis suggests the diagnosis of ocular sarcoid.
