Ocular Manifestations of Biopsy-Proven Pulmonary Sarcoidosis in Korea

To investigate the clinical features and ocular manifestations of biopsy-proven pulmonary sarcoidosis in Korea.

55 patients diagnosed with pulmonary sarcoidosis by bronchoscopic or excisional biopsy were included. By retrospective clinical chart review, we investigated features of uveitis, ocular and systemic treatments, visual acuity, angiotensin-converting enzyme level, chest radiography, and pulmonary function tests. Clinical features were analyzed by presence of uveitis, site of biopsy, and first manifested sign of sarcoidosis.

The group with uveitis (n = 39) presented with higher systemic (71.8%) and immunosuppressive treatment rates (35.9%) than the group without uveitis (31.3%, 0%, resp.) (P = 0.007, P = 0.005, resp.). There were no significant differences in clinical features, including systemic treatment rate, by type of biopsy. Of 39 patients with uveitis, the group with ocular manifestation as a first sign of sarcoidosis showed higher systemic and immunosuppressive treatment rates (88.9%, 55.6%) compared to the group with pulmonary manifestation as a first sign (57.1%, 19.0%) (P = 0.037, P = 0.018, resp.).

In patients with biopsy-proven pulmonary sarcoidosis, the presence of ocular involvement and uveitis as a first sign could be significant factors associated with higher systemic treatment rate, especially with immunosuppressive agents. Biopsy site determined by location and size had no influence on clinical features.
