Ocular manifestation of sarcoidosis occurs in up to 60% of patients with confirmed systemic sarcoidosis and represents one of the most common forms of noninfectious uveitis. In known pulmonary sarcoidosis, ocular involvement can occur in up to 80% of cases. Sarcoidosis can also present only in the eye, without a systemic manifestation (ocular sarcoidosis). Typically, ocular sarcoidosis shows bilateral granulomatous uveitis and can involve all parts of the eye. Apart from an acute anterior uveitis, chronic intermediate or posterior uveitis can be found. In order to prevent a severe reduction of visual acuity leading to blindness, early diagnosis and treatment is essential. For diagnosis, specific clinical signs involving the eye (bilateral granulomatous changes in all parts of the eye) and typical laboratory investigations (angiotensin-converting enzyme, ACE; lysozyme; soluble interleukin 2 receptor, sIL2R; chest XaEuroray; chest CT) have to be taken into account, since biopsy to prove noncaseating granulomas is not performed with changes restricted to the eye due to the high risk of vision loss. Ocular sarcoidosis mostly responds well to local or systemic steroid treatment. If the therapeutic effect is insufficient, immunosuppressive agents and biologics can be applied.
