Iris nodules in Fuchs' heterochromic uveitis.

Four black patients with Fuchs' heterochromic uveitis had multiple nodules in the iris. The iris nodules were small, transparent, and scattered across the whole surface of the iris (Busacca's nodules) but increased in density toward the pupillary border. All four patients also had nodules at the pupillary border (Koeppe's nodules). Repeated etiologic screening for systemic diseases in these patients was noncontributory. Unilateral multiple iris nodules without the formation of synechiae may be encountered as part of Fuchs' heterochromic uveitis syndrome and may be important in the identification of Fuchs' heterochromic uveitis, especially in black patients.
