Introduction  It has been recognized for many years in Africa and in certain areas of Central and South America that microfilariae of Onchocerca volvulus produce blindness (O'Connor and Hulse, 1932; Hissette, 1938, and Clark, 1947). Insect larvae have frequently been found to cause ocular myiasis (Anderson, 1935), and patients with African sleeping sickness have been reported to experience keratitis, iridocyclitis, and choroiditis (Ridley, 1945).However, additional significant reports involving the relationship of other animal parasitic infections to uveitis have been presented within the last few years and require our attention.

  1. Helminths

    • Microfilariae other than those of Onchocerca: choroidal degeneration associated with microfilaraemia of Wuchereria, reported by Crawford et al. (1954)

    • Migratory larvae of Nematoda, reported by Wilder (1950), Nichols (1956), and Beaver (1956)

  2. Protozoa

    • Toxoplasma gondii as a cause of chorioretinitis, reported by Wilder (1952)

    • Central serous choroidosis associated with amebiasis, reported by Braley and Hamilton
