Ophthalmologic Findings in Fetal Alcohol Spectrum Disorders : A Cohort Study From Childhood to Adulthood

• PURPOSE: To investigate whether ophthalmologic findings in children with fetal alcohol spectrum disorders (FASD) persist into young adulthood.DESIGN: Prospective cohort study.METHODS: Thirty children (13 female) adopted from eastern Europe to Sweden in the 1990s and diagnosed with FASD by a multidisciplinary team at the median age of 7.9 years were followed up by the same team 13-18 years later. Visual acuity (VA), refraction, stereoacuity, strabismus, ocular media, and fundus were investigated.RESULTS: Median VA in right/left eye (OD/OS) was 20/32/20/32 (0.2/0.2 logMAR) in childhood and 20/22/20/20 (0.05/0.0 logMAR) in adulthood. Median (range) refraction OD/OS was +0.88/+1.25 (-8.75 to +4.75/-9.38 to +5.25) spherical equivalent diopter (D) in childhood and -0.25/-0.25 (-12 to +2.75/-13.25 to +2.63) in adulthood. Astigmatism (≥1 D) was the most common refractive error, in 13 (40%) and 14 (47%) subjects, respectively. Defective stereoacuity (>60 arc second) was noted in 20 subjects (67%) in childhood and 22 (73%) in adulthood. Heterotropia occurred in 12 subjects (40%) in childhood and 13 (43%) in adulthood. Increased tortuosity of the retinal vessels was found in 8 (27%) subjects in childhood vs 11 (37%) in adulthood. Optic nerve hypoplasia was recorded in 3 children and in 4 young adults.CONCLUSIONS: Ophthalmologic findings such as refractive errors, strabismus, and fundus abnormalities are frequent in children with FASD and persist into early adulthood. The facial features characteristic of FAS diminish with age, making a dysmorphology evaluation in adulthood less reliable. An ophthalmologic examination is an important part of the evaluation of FASD in childhood as well as in young adulthood.
