Congenital glaucoma: genetic models.

Modes of inheritance of congenital glaucoma have been studied. Two methods of analysis, complex segregation analysis and frequency of congenital glaucoma in second- and third-degree relatives, did not permit one to retain a unitary mode of inheritance ofthis malformation. Genetic heterogeneity of congenital glaucoma is proposed. Recurrence risks and guidelines for genetic counseling in specified situations are given.
