Intermediate uveitis etiology, complications, treatment, and outcomes in a Colombian uveitis referral center

Purpose: To analyze the etiology, clinical characteristics, complications, treatments and outcomes of patients with intermediate uveitis examined at a uveitis referral center in Bogotá, Colombia. Patients and Methods: A retrospective descriptive study was performed. Medical records of patients attending a uveitis referral center in Bogotá, Colombia, between 2013 and 2020 were systematically reviewed. Data analysis included demographics, etiology, clinical characteristics, treatment modalities, best-corrected visual acuity, and complications. Absolute and relative frequencies were used for categorical variables, while means and standard deviations were calculated for continuous variables. Results: Eighteen patients with intermediate uveitis were identified. The mean age at disease onset was 19.4 years. There was no gender predominance. Two thirds of the patients had bilateral involvement. Mean initial best-corrected visual acuity was 0.19 LogMAR. The most frequent etiology was idiopathic, followed by undetermined, tuberculosis, multiple sclerosis and juvenile idiopathic arthritis. The most common features were insidious onset, chronic course and persistent duration. Complications encountered were macular edema, optic disc edema, cataract, epiretinal membrane, among others. Corticosteroids and immunosuppressive therapy were the most common treatments.
