[Alcohol during pregnancy damages eye and vision development].

Maternal alcohol abuse during pregnancy causes malformations of the eyes with serious consequences to the vision of the affected children. A high percentage (up to 90 per cent) of children suffering from the fetal alcohol syndrome have eye abnormalities of different kinds. The most typical are hypoplasia of the optic nervehead and increased tortuosity of the retinal vessels, especially of the arteries, both occurring in up to half of the cases. Visual acuity is often reduced. Considering the developmental timing of different tissues of the eye, one can presume that there is a risk for deleterious effects of alcohol on eye structures at any point of time from early gestation until development is completed.
