Intermediate Uveitis Etiology, Complications, Treatment, and
A Study was conducted to analyze the etiology, clinical characteristics, complications, treatments, and outcomes of patients with intermediate uveitis examined in a uveitis referral center in Bogotá, Colombia.

The clinical records of patients were reviewed systematically. Data analysis included demographics, etiology, clinical characteristics, treatment modalities, best-corrected visual acuity, and complications. For categorical variables, absolute and relative frequencies were used while for continuous variables mean and standard deviations were calculated.

--18 patients were identified with intermediate uveitis. The mean age at disease onset was 19.4 years. There was no sex predominance.

--Two-thirds of the patients presented bilateral involvement. The mean initial best-corrected visual acuity was 0.19 LogMAR.

--The most common etiology was idiopathic followed by undetermined, tuberculosis, multiple sclerosis, and juvenile idiopathic arthritis.

--The most common characteristics were insidious onset, chronic course, and persistent duration. The complications found were macular edema, optic disk edema, cataract, epiretinal membrane, among others.

--Corticosteroids and immunosuppressive therapy were the most common treatments. Mean follow-up time was 24.4 months, and the mean final best-corrected visual acuity was 0.12 LogMAR.

This study describes intermediate uveitis features in South America. Moreover, Intermediate uveitis is infrequent. Polyautoimmunity and familial autoimmunity phenomena were found in some patients who may require a multidisciplinary approach. Ophthalmologists should promptly diagnose, treat, and refer patients with this disease to avoid common complications.
