Visual impairment and ocular abnormalities in children with fetal alcohol syndrome.
Children with fetal alcohol syndrome (FAS) may have impaired vision and various ocular abnormalities. All parts of the eye may be affected and anomalies such as microphthalmus, microcornea, Peters' anomaly, cataract, persistent hyperplastic primary hyaloid vitreous body, coloboma of the iris and choroid, retinal dysplasia and, most commonly, optic nerve hypoplasia and tortuosity of the retinal vessels, have been reported. The periocular facial features consist of short palpebral fissures (included in the criteria for diagnosis of FAS), telecanthus, epicanthus and blepharoptosis. Visual function may be reduced to a moderate or severe degree. Refractive errors and strabismus are common. Considering the high frequency of ocular pathology in FAS, an ophthalmological examination is helpful in making the diagnosis. The early detection of impaired vision and ocular abnormalities in affected children is important in the management of the disorder. In this article, the ophthalmological signs and symptoms in children with FAS are presented.
