Abstract:
To describe the epidemiology of uveitis in northern Bénin. This retrospective study carried out from records describing 10 years of uveitis care in 2 eye clinics in northern Bénin. The sample of 623 eyes with uveitis in 489 patients accounted for 1.0% of all consultations. A male predominance was observed with a sex-ratio of 1.5 (297 m/192 F). The patients' mean age was 35.7 ± 16.1 years, and the age range most often affected was 20-39 years. The uveitis was anterior in 32.3 %, posterior in 29.0 %, intermediate in 28.1% and total (panuveitis) in 10.6%. The cause was undetermined in 85.7 % of cases and identified in 14.3%, including toxoplasmosis in 47 cases (7.5%) and herpes zoster in 20 cases (3.2%). Outpatients accounted for all cases, and all received topical corticosteroids. Some complications were observed. Uveitis has a prevalence rate of 1% in northern Bénin. It caused blindness in 9.8% of affected eyes and impaired vision in 49.3%.
