We report on 2 brothers with chorea and monocular horizontal nystagmus
beginning in early infancy, both of which remit during the first deca
de of life, and peripheral cataracts. While this condition shares mani

vement disorders, the slowly remitting course of the chorea combined w
ith the visual abnormalities appears to be unique. (C) 1993 Wiley-Liss
