Diagnostic aspects of ocular sarcoidosis

Ocular manifestations are seen in at least one-fifth of sarcoidosis patients. Characteristic biomicroscopic and photographic features raise the suspicion of ocular sarcoidosis. Systemic sarcoid associations and compatible laboratory findings, together with the result of an eventual conjunctival biopsy further support the diagnosis. The diagnosis of chronic ocular sarcoidosis is difficult if other systemic symptoms and signs have been resolved. In these cases taking a careful history and searching for conjunctival granulomatosis and residues of intraocular granulomas are important.
