[Clinical characteristics of patients with biopsy-proven sarcoid uveitis].

To investigate the clinical features of patients with biopsy-proven sarcoid uveitis. The clinical data of the patients with biopsy-proven sarcoid uveitis who consulted the Ophthalmic Clinic of Beijing Tongren Hospital from February 2012 to February 2020 was retrospectively reviewed and analyzed. All the patients underwent visual acuity test, slit lamp microscopy, indirect ophthalmoscopy, fundus fluorescein angiography (FFA), chest computed tomography (CT) and other auxiliary examinations. A total of 9 patients (18 eyes) (6 females, 3 males) with biopsy-proven sarcoid uveitis were included in the study, with a mean age of (52.6±9.0) years. Based on the modified Scadding classification, there were 2 and 7 cases of Stage Ⅰ and Ⅱ sarcoidosis, respectively. The ocular symptoms were the initial presenting complaints in 6 patients, who had a time from onset to diagnosis of 9.0 (2.6, 20.3) months. Three patients had a history of sarcoidosis. Fever was reported in 2 patients, fatigue in 3 patients, body weight loss in 3 patients, respiratory problems in 5 patients, with bilateral ocular involvement in all the patients. Among the 18 eyes, panuveitis occurred in 10 eyes, posterior uveitis in 4 eyes, anterior uveitis in 4 eyes, mutton fat keratic precipitates (KP) in 10 eyes, granular KP or no obvious KP in 8 eyes, posterior synechia of the iris in 9 eyes, cataract in 8 eyes, inflammatory vitreous opacity in 8 eyes, macular edema in 7 eyes, epiretinal membrane in 6 eyes, retinal vasculitis in 2 eyes, glaucoma in 2 eyes, and optic disc granuloma in 2 eye. Among the 13 eyes whose peripheral ocular fundus was visible, multiple chorioretinal peripheral lesions were found in 5 eyes. Chest CT should be performed in the uveitis patients with older age, female gender, bilateral ocular involvement, the symptom of fever, body weight loss and respiratory problems in time to exclude the sarcoid uveitis. Sarcoid uveitis may presents with granular KP or no obvious KP, and the posterior segment of the eye ball was the most commonly involved area.
