Infectious causes of uveitis in the developing world.

Infectious causes of uveitis are common in the developing world and include some causes that are rarely encountered in industrialized nations, such as tuberculosis, leptospirosis, leprosy, onchocerciasis, and cystercicosis. Ocular toxoplasmosis occurs in all countries but is more common in Central and South America, the South Pacific, and western Europe. AIDS-related opportunistic infections occur wherever HIV infection is prevalent, including North and South America, western and eastern Europe, the former Soviet Union, sub-Saharan Africa, and South and Southeast Asia. Physicians who care for patients in the developing world should consider these infectious possibilities whenever their patients develop uveitis.
