Ultrasonographic visualization of the fetal eye.
This paper describes the analysis of the fetal eye in utero using ultrasonography. Such analysis has allowed the diagnosis of two cases of cyclopia and one case of microphthalmia. Two of the three pregnancies of a woman affected by autosomal dominant aniridia were found to be normal at 17 weeks of gestation and at birth; her oldest daughter was affected. The motility of the eyes was also noted when the fetus was examined. No movement or rapid and slow movements are seen more frequently as the fetus progresses through pregnancy. The centiles for the intermalar and interethmoidal distances are described for fetuses between weeks 10 and 40 of gestation. This system should be used with caution because of the difficulties in interpreting views of the fetal eye.
