Clinical characteristics of intermediate uveitis in Tunisian patients.
To analyze the pattern of intermediate uveitis (IU) in a referral center in Tunisia, North Africa. A retrospective, descriptive study of 87 consecutive patients (145 eyes) examined at the Department of Ophthalmology of Monastir (Tunisia) from January 1996 to August 2008. All patients underwent an extensive ocular and systemic history, a complete ophthalmic examination, and fluorescein angiography. Standard diagnostic criteria of IU were employed. The mean follow-up period was 43.2 months (range, 4-65 months). The mean age at diagnosis of IU was 29.1 years (range, 5-54 years). The male-to-female ratio was 1:1.6. Both eyes were affected in 58 patients (66.7%). The best-corrected visual acuity at onset of uveitis ranged from light perception to 20/20 (mean, 20/32). The most frequent ocular findings were vitritis (100%), snowballs (53.8%), and retinal vasculitis (28.3%). Concurrent anterior uveitis was noted in 38.6% of affected eyes. Intermediate uveitis was most commonly idiopathic (86.2%). Systemic associations were found in 13.8%; sarcoidosis (9.2%) and multiple sclerosis (2.3%) were the most common systemic diseases. The ocular complications that developed during the follow-up period included cystoid macular edema (39.3%), cataract (31.7%), inflammatory optic disc involvement (26.2%), and glaucoma or ocular hypertension (9%). One hundred-twelve affected eyes (77.2%) had a final visual acuity more than or equal to 20/40. Factors of poor visual outcome were initial VA less than 20/40 (P = 0.00011), CME (P = 0.0016), and vitritis more than 3+ cells (P = 0.023). In a hospital population in Tunisia, intermediate uveitis started frequently at the 3rd decade. This type of uveitis was most commonly idiopathic. Cystoid macular edema and cataract were the most frequent complications. Visual prognosis appeared to be fairly good.
