[Mesodermal dysgenesis of the anterior segment].

A patient is 18 years old; he presents Peters' anomaly, microcornea, the persisting of papillar membrana, congenital specifying lens for both eyes and atypical iridic coloboma for the right eye. The eye sight is diminished under the limit of practice usefulness for both eyes. The disease is thought to be a mesodermal dysgenesis of the anterior segment having some persisting fetal structures. The absence of such lesions within the same family pleads for the action of a teratogen factor that have belated action during the 4th-5th month of pregnancy.
