Peters' anomaly with the fetal transfusion syndrome.

Of identical twins with the fetal transfusion syndrome, the second twin who was anemic and hypoxemic from early gestation had Peters' anomaly by histologic examination of the host cornea excised during corneal transplantation at 7 months of age. The absence of a normally positioned lens with the incorporation of lens epithelium, capsule, and cortex within the posterior corneal stroma suggested a developmental disturbance in the separation of the lens from the cornea. The severe lenticular disturbance, microphthalmos, and fetal growth retardation in this case reflected early anemia and the resultant hypoxemia. To our knowledge, this is the first time that the fetal transfusion syndrome and Peters' anomaly have been associated.
