[Eye manifestations of fetal alcohol syndrome]

Alcohol is the most frequent and most important teratogenic agent causing mental and physical retardation in childhood. The alcohol fetal syndrome is characterized by pre- and postnatal growth retardation, hypotonia, hyperactivity, microcephalus, mental retardation and typical craniofacial malformations. The latter includes short palpebral fissures, a poorly developed philtrum, thin upper lip vermillion, short mandibles, a flattened midface structure and dysplastic ears. Ophthalmological signs occur in 90% and include epicanthus, ptosis, myopia, optic nerve hypoplasia and tortuous retinal vessels. Microphthalmus, coloboma and Peters' anomaly have also been described. Five children with alcohol embryopathy are presented. The histopathological findings of the enucleated eye of a 6th child with alcohol embryopathy which was sent to us for examination and which revealed an anterior staphyloma with Peters' anomaly is also described. Ophthalmologists should be aware of alcohol in pregnancy as a preventable cause of eye malformation.
