Background. The eye is a sensitive indicator of adverse effects of prenatal alcohol exposure. Anomalies of the eyes and their adnexa are known to be associated with the fetal alcohol syndrome (FAS), although long-term effects of these malformations are unknown. Design. A prospective ophthalmologic follow-up (median, 11 years; range, 4 to 19 years) was performed in 25 children with FAS. Their social situation and educational status were also investigated. Results. All but one of the children had ophthalmologic abnormalities. Fundus anomalies were observed in 23 children, of whom 19 had optic nerve hypoplasia. Thirteen children had concomitant strabismus. Microphthalmos, buphthalmos, phthisis, microcornea, coloboma of the iris and uvea, blepharoptosis, cataract, persistent hyperplastic primary vitreous, and nystagmus were observed in single cases. The dysmorphology of the eyes remained unchanged during the follow-up period. In 2 children with severe mental retardation and, initially, very poor vision, the severe visual handicap persisted. Seventeen children had an initial visual acuity ≥20/70, which remained unchanged in 10 children and improved in 7 children, despite the presence of optic nerve hypoplasia in 14 of the children. Ten mothers died, 8 of them because of alcohol-related diseases, and only 4 of the mothers were able to take care of their children. Sixteen children went to schools for the mentally retarded, and only 3 children had a normal school education without extra teaching assistance. Conclusions. In children with FAS, the major sequela, ie, brain damage, remains despite extensive medical, educational, and social support. The presence of ophthalmic signs, which persisted but did not deteriorate during the follow-up period, strengthens the diagnosis of FAS, and the high frequency of ocular involvement indicates the importance of a complete ophthalmologic evaluation in children with FAS.

Optic nerve hypoplasia was detected in up to one half of a group of Swedish children born to alcoholic mothers. Using an experimental model of pre- and postnatal alcohol exposure in rats fed a liquid diet, reduced optic nerve size from gestational day 21 (294 ± 26×102 μm2 vs 502 ± 16×102 μm2; n=6; p≤0.001) to later in development was observed as a result of the daily mean blood alcohol levels achieved in dams and their offspring. Altered glial cells and degenerating and atrophic optic axons, myelin sheaths and ganglion cells were frequent in the alcohol-exposed optic nerves. Smaller optic nerve (1,918 ± 61×102 μm2 vs 2.195 ± 40×102 μm2; n=4; p≤0.001), reduced gaglion cell and axonal densities, and ultrastructural damage to the macroglial cells and myelin sheaths were also detected in the treated group. All these changes remained in the retina and optic nerve of the oldest rats, as a consequence of the long-lasting effects of prenatal alcohol exposure. In summary, alcohol as a major teratogenic agent may induce dysmorphogenesis and irremediable damage to the retina and optic nerve, which frequently manifests itself as hypoplastic optic nerve.

The primary focus of this volume is on the impact of alcohol on brain development. It is a perfect example of how research on both animals and humans can interact to produce very important findings. In the case of prenatal alcohol exposure, dialogue between animal and human researchers has proved to be very profitable for both lines of research. Initial observations by human researchers identified a syndrome of facial stigmata, physical malformations, and early behavioral disturbances that was related to maternal alcohol abuse during pregnancy. They gave this syndrome the name Fetal Alcohol Syndrome. However, human researchers were unable to state unequivocally that prenatal alcohol exposure was teratogenic to the fetus. Thus, they turned to animal researchers who were able to model Fetal Alcohol Syndrome in a variety of animals and to confirm the teratogenicity of alcohol on the developing fetus. The quarter century of studies of the damage caused by prenatal alcohol exposure is replete with such interactions between these two groups of researchers. Without the input and pioneering studies of animal researchers on the effects of prenatal alcohol exposure, human researchers would have much less understanding of the damage caused by alcohol exposure in utero or insights into possible treatment or remediation strategies for those damaged by alcohol exposure.

Abstract Possible mother-to-child transmission of severe acute respiratory syndrome-coronavirus type 2 (SARS-CoV-2) during pregnancy is still a matter of debate. We studied the impact of SARS-CoV-2 infection on 56 complete households, including 27 newborns whose mothers were pregnant when exposed to the virus. Three perinatal SARS-CoV-2 transmissions with mild symptoms in affected neonates were recorded (two cases confirmed by PCR, the third one based on clinical findings). In addition, we observed a severe eye malformation (unilateral microphthalmia, optic nerve hypoplasia, and congenital retinopathy) associated with maternal SARS-CoV-2 infection in weeks 5 and 6 of embryonic development. This embryopathy could not be explained by other infectious agents, genetic factors, or drug use during pregnancy. Eight other women with a history of SARS-CoV-2 infection prior to gestational week 12, however, delivered healthy infants.Conclusion: The repeated occurrence of mother-to-child transmission in our cohort with risks that remain incompletely understood, such as long-term effects and the possibility of an embryopathy, should sensitize researchers and stimulate further studies as well as strongly support COVID19 vaccination recommendations for pregnant women.Trial registration number: NCT04741412Date of registration: November 18, 2020

Speech of children with fetal alcohol syndrome (FAS) has been little studied compared to language. Becker, Warr-Leeper, and Leeper (1990), found a relationship between prenatal alcohol exposure, oral motor control, and speech articulation. Behavioral tests suggest deficits in focal oral motor control specific to children with FAS (Bolinger & Dembowski, 2010). The current project extends that investigation through acoustic measures. Peak and mean frequencies of stop consonant releases were used to infer control of place of articulation. Voice onset time (VOT) was used to infer articulatory-laryngeal coordination. Preliminary measures on 3 experimental speakers and 2 matched neurotypical controls suggest higher stop consonant frequencies in the experimental group, with a poorer distinction between alveolar and velar stops than in the control group. Voiced VOT values were significantly longer for FAS children than for controls. Mean voiceless VOTs were similar across groups, but substantially more variable for the FAS children. Values may be interpreted as acoustic evidence for specific speech motor control deficits in FAS children relative to matched neurotypical children.
