Abstract
Two infants with cyclops malformation were born at the University of Southern California Medical Center during the past three years. The karyotypes of both infants demonstrated an extra chromosome No. 13: one with 47,XX,+13 and one with 46,XX,-14,+t(13q14q). The physical findings, karyotypes with trypsin-Giemsa banding, and association of trisomy 13 syndrome with cyclops malformation are presented.
