Abstract： Objective:To analyze the clinical features of patients with sarcoid uveitis.Methods:This was a retrospective case series study. The medical records of 19 086 patients with uveitis admitted to the Department of Ophtalmology, The First Affiliated Hospital of Chongqing Medical University from April 2008 to December 2019 were collected. The general data, medical history, treatment, diagnosis, follow-up, ophthalmic and other auxiliary examinations were retrospectively analyzed. The paired sample Wilcoxon signed rank test was used to compare the best corrected visual acuity (BCVA) of the affected eye at the first visit to the BCVA of the affected eye at the corresponding last visit.Results:A total of 51 patients (97 eyes) with sarcoid uveitis were included, including 15 males (29.4%) and 36 females (70.6%), with a male/female ratio of 1/2.4. There were 46 patients (88 eyes) with presumed sarcoidosis and 5 patients (9 eyes) with definite sarcoidosis. The age of onset was 48 (40, 55) years and 90.2% of patients (46 cases) were involved in both eyes, while 88.2% of the patients (45 cases) were chronic, and only 11.8% (6 cases) showed acute inflammatory response. Anterior uveitis was the most common type (50.5%, 49 eyes). Ophthalmoscopy revealed retinal vasculitis in only 2 eyes (2.1%) and fundus fluorescence angiography (FFA) revealed diffuse vascular leakage of fluorescein in 64 eyes (66.0%). Thirty-one patients (59 eyes) were followed up for≥3 months. Cataract was the most common ocular complication, accounting for 44.1% (26 eyes), and the inflammatory response was controlled in 45 eyes (76.3%) treated with combination of corticosteroids and immunosuppressive agents. The patients were followed up for 21.5 (13.7, 29.3) months. Among 31 patients (59 eyes) followed up for≥3 months, BCVA was≥0.8 in 25 eyes (42.3%) and<0.3 in 15 eyes (25.4%) at the last follow-up, BCVA of 59 affected eyes of 31 patients was better than that at the first visit, the difference was statistically significant ( Z=-2.76, P=0.006). Conclusions:Uveitis associated with sarcoidosis or presumed ocular sarcoidosis mainly manifests as a bilateral, chronic anterior uveitis with a subclinical retinal vasculitis. FFA shows subclinical retinal vasculitis in most patients. Glucocorticoid therapy in combination with other immunosuppressive agents can control inflammatory responses and improve visual acuity in most patients.
