Prenatal detection of congenital inherited cataracts.

In a high-risk pregnancy for ocular defects, routine second-trimester ultrasonography revealed a highly echogenic area within the fetal left eye with no other associated abnormalities. The diagnosis of congenital cataracts was confirmed after birth. Examination of the fetal face is an important part of prenatal ultrasonography, and visualization of the fetal eyes and lenses should be included in the routine assessment of facial anatomy. This is especially important in pregnancies at risk for congenital cataracts or for other anomalies affecting the fetal eye.
