Fetal alcohol spectrum disorders from childhood to adulthood: a Swedish population-based naturalistic cohort study of adoptees from Eastern Europe

Pregnancy characteristics and outcomes among birthing individuals with a diagnosis of fetal alcohol syndrome

BACKGROUND

Fetal alcohol syndrome (FAS) can have adverse effects on health outcomes throughout the life course. Adults with FAS have an increased risk of chronic and infectious diseases. Although these conditions can affect reproductive health, few have described perinatal outcomes among individuals with an FAS diagnosis.

METHODS

We analyzed data from the Study of Mothers and Infants, an administrative birth cohort derived from California birth certificates linked with a hospital discharge database. The cohort consisted of 7.3 million singleton, live births between 2005 and 2021. FAS was identified by International Classification of Diseases (ICD) codes in maternal hospital discharge records. Pregnancy and birth outcomes were captured via ICD codes in maternal or infant records. We performed descriptive analyses for pregnancy and birth outcomes by maternal FAS diagnosis.

RESULTS

There were 35 babies born to 30 individuals with an FAS diagnosis between 2005 and 2021 (0.5/100,000 live births). The prevalence of births to individuals with an FAS diagnosis increased over the period. Individuals with an FAS diagnosis were more likely to identify as non-Hispanic White, or "other/multiple" race, and less likely to be Hispanic than those without FAS. They were also more likely to be publicly insured and less than 18 years old. Birthing individuals with FAS were also more likely to use nicotine during pregnancy and to have diagnoses of mental health disorders, epilepsy, substance use disorders, preexisting or gestational hypertension, and sexually transmitted infections or other infections complicating pregnancy. Infants of individuals with FAS were more likely to be born prematurely or small for gestational age and be admitted to the neonatal intensive care unit.

CONCLUSIONS

These findings highlight the need for improved recognition of FAS among birthing people. The results suggest that individuals with FAS would benefit from early and sustained medical care prior to pregnancy to optimize perinatal outcomes.

A systematic review: facial, dental and orthodontic findings and orofacial diagnostics in patients with FASD

Background

The fetal alcohol spectrum disorder is a group of developmental disorders caused by maternal alcohol consumption. Patients with fetal alcohol syndrome show abnormal orofacial features. This review presents an overview over the facial, oral, dental or orthodontic findings and diagnostic tools concerning these features.

Methods

For this systematic review Cochrane, Medline and Embase databases were considered and the review was performed according to the PRISMA checklist. Two independent reviewers evaluated all studies and recorded results in a summary of findings table. Risk of bias was analyzed via Quadas-2 checklist.

Results

61 studies were eligible for inclusion. All included studies were clinical studies. Methods and results of the studies were not comparable, guidelines or methods for the detection of FASD varied across studies. Facial features most often measured or found as distinguishing parameter were: palpebral fissure length, interpupillary or innercanthal distance, philtrum, upper lip, midfacial hypoplasia or head circumference.

Conclusions

This review shows that to date a multitude of heterogeneous guidelines exists for the diagnosis of FASD. Uniform, objective diagnostic criteria and parameters for the orofacial region in FASD diagnosis are needed. A bio database with values and parameters for different ethnicities and age groups should be made available for diagnosis.

Visual and ocular findings in children with fetal alcohol spectrum disorders (FASD): validating the FASD Eye Code in a clinical setting

Objective

Fetal alcohol spectrum disorders (FASD) is an umbrella term covering a spectrum of medical conditions caused by prenatal alcohol exposure. The FASD Eye Code is a new complementary ophthalmological diagnostic tool created to corroborate the complex FASD diagnosis. The aim of this work was to validate the FASD Eye Code by testing it on a second group of children diagnosed with FASD in a clinical setting.

Methods and analysis

A clinical study was carried out in a group of 21 children (13 males, 8 females, mean age 13.3 years) investigated for suspected FASD and a healthy sex-matched and age-matched control group (n=21). The participants underwent a detailed ophthalmological examination including visual perception problems (VPPs) assessment. Clinical examination results were compiled, and total scores were calculated according to the FASD Eye Code protocol (range 4–16).

Results

The median total score in the FASD group was 8. Eight individuals in the FASD group and none of the controls obtained a total score of ≥9 corresponding to 38% sensitivity and 100% specificity with an area under the curve of 0.90. A cut-off total score of ≥8 showed 52% sensitivity and 95% specificity. One individual in the FASD group versus 12 controls had a total score of 4, representing normal findings. No significant difference between the two groups regarding VPPs was seen.

Conclusion

The FASD Eye Code can be used as a complementary diagnostic tool for FASD to assist in diagnosis and to detect ophthalmological abnormalities in individuals with suspected FASD.

Autism under the umbrella of ESSENCE

This brief article gives a short overview of "comorbidity" in autism. The most common co-occurring disorders will be presented and discussed within the context of ESSENCE (Early Symptomatic Syndromes Eliciting Neurodevelopmental Clinical Examinations), a concept that provides a holistic perspective for neurodevelopmental disorders. The ESSENCE concept also considers the heterogeneous and changing clinical panorama of developmental disorders over time, and also the multifactorial etiologies, including so called behavioral phenotype syndromes. Aspects on behavioral interventions in autism are presented-interventions that need to be adapted and take into account all non-autism associated ESSENCE, including intellectual disability and Attention-Deficit/Hyperactivity Disorder (ADHD). The article also focuses on current research on pharmacological intervention based on the hypothesis of imbalance in excitatory/inhibitory transmitter systems in autism and some other ESSENCE.

Fetal alcohol spectrum disorders and access to regional center services in San Diego County

BACKGROUND

Fetal alcohol spectrum disorders (FASD) are developmental disabilities that are estimated to occur in 2-5% of elementary school children and that negatively impact a child's ability to function without support. Timely diagnosis-informed interventions are crucial to optimizing the developmental trajectory of children with FASD. The true prevalence of FASD among children receiving services for developmental disabilities is unknown.

METHODS

An FASD prevalence study was carried out between 2011 and 2014 among a sample of 5- to 7-year-old children who were receiving services provided by the California State Regional Center for Developmental Disabilities in San Diego County. Children whose parent or caregiver consented were evaluated using the Collaboration on Fetal Alcohol Spectrum Disorders Prevalence study assessment protocol and classification criteria.

RESULTS

Among 216 eligible caregiver-child dyads, 44 completed assessments that were sufficient to obtain a classification for FASD, including fetal alcohol syndrome (FAS), partial FAS, alcohol-related neurodevelopmental disorder, or no fetal alcohol spectrum disorder. Fifteen children were classified as meeting the criteria for an FASD. A minimum FASD prevalence rate of 69.4 per 1000 (6.9%) among all eligible children was estimated. None of the children classified as FASD were receiving services because of an FASD diagnosis, and none had previously been diagnosed with FASD. Autism was the most common qualifying diagnosis for which children classified as FASD were receiving services.

CONCLUSIONS

The 6.9% prevalence estimate among Regional Center clients was higher than the prevalence estimate of 2.3% in the same community among 5- to 7-year-old children in the general population, though the estimate was based on only 20% of eligible dyads. All children in the sample were receiving Regional Center services for another diagnosis. Barriers to eligibility for services for children with FASD may lead to less than optimum care for these children. Study findings support the facilitation of access to developmental services for children with FASD.

Suicidality and Associated Factors Among Individuals Assessed for Fetal Alcohol Spectrum Disorder Across the Lifespan in Canada

OBJECTIVE

Individuals with fetal alcohol spectrum disorder (FASD) experience a range of complex neurodevelopmental, psychological, and socioenvironmental vulnerabilities. There is growing evidence that suicidal ideation, attempts, and death by suicide are significant concerns within this population. In this study, we (1) determined the rate of suicidal ideation/attempts in a large group of individuals with prenatal alcohol exposure (PAE) who were assessed for FASD in Canada and (2) investigated the associations between suicidal ideation/attempts and select demographic and biopsychosocial factors in this group.

METHOD

A secondary analysis of data from Canada's National FASD Database, a national repository of clinical information gathered through FASD assessment and diagnostic clinics across the country, was conducted. Descriptive analyses, chi-square/Fisher's exact tests, and binary logistic regression were used to examine demographic and biopsychosocial variables and their associations with suicidality.

RESULTS

In our sample of 796 participants (M_age = 17.7 years, range = 6-59; 57.6% male) assessed for FASD, 25.9% were reported to experience suicidal ideation/attempts. Numerous demographic and biopsychosocial factors were found to be significantly associated with suicidal ideation/attempts. The strongest associations with suicidal ideation/attempts were substance use, history of trauma/abuse, and impaired affect regulation.

CONCLUSIONS

With this study, we contribute to the emerging evidence of elevated risk of suicidality among individuals with PAE/FASD and improve our understanding of factors that may exacerbate this risk. Findings have relevance for improving screening, prevention, and proactive treatment approaches for individuals with PAE and FASD, their families, and wider support systems.

Deficits in attention, motor control and perception childhood to age 30 years: prospective case-control study of outcome predictors

OBJECTIVE

Investigate predictors of adverse outcome in children with and without attention-deficit/hyperactivity disorder (ADHD) combined with developmental coordination disorder (DCD) at 6 years of age.

DESIGN

Prospective population-based cohort study.

SETTING

Western Sweden.

PARTICIPANTS

From a screening-based population cohort of 589 individuals, 62 (11 female) diagnosed with ADHD+DCD at mean age 6.6 years, and a comparison group of 51 population-matched (10 female) children were followed prospectively.

OUTCOME MEASURES

Drawn from a clinical reassessment at age 9 years of 110 of the 113 individuals, neuropsychiatric symptoms, continuous performance test results and measures of motor function were used as predictors of outcome in linear regression models. Participants were followed in national registers up to 30-31 years of age for outcomes in adulthood. Predictors were regressed onto an adverse outcome score (range 0-7) comprising seven binary endpoints, and when applicable onto each continuous outcome separately (low educational attainment, low occupation level, psychiatric disorder, psychotropic medication prescription, sick pension, high dependence on social benefits and criminal conviction).

RESULTS

Of the 110 individuals, 3 had died. In univariable regression onto the adverse outcome score, the strongest predictors at age 9 years were symptoms of conduct disorder, oppositional defiant disorder, ADHD and motor dysfunction, with an R² around 25%, followed by autistic traits (R²=15%) and depressive symptoms (R²=8%). Combining these six strongest predictors in a multivariable model yielded an adjusted R²=38%. Subgroup analyses were similar, except for a strong association of autistic traits with the adverse outcome score in females (n=20, R²=50%).

CONCLUSION

Several neurodevelopmental symptoms, including ADHD severity at age 9 years, accounted for a considerable amount of the variance in terms of adulthood adverse outcome. Broad neurodevelopmental profiling irrespective of diagnostic thresholds should inform research and clinical practice. The study highlights the importance of considering associated comorbidities and problems in ADHD.

Unfitness to stand trial and fetal alcohol spectrum disorder: Understanding and responding to FASD within the criminal justice system in New Zealand

Fetal alcohol spectrum disorder (FASD) is an increasingly important issue in the New Zealand (NZ) Criminal Justice System (CJS). FASD may impact an offender's ability to participate meaningfully in the trial process, giving rise to the issue of unfitness to stand trial. Capacity to apprehend, comprehend, participate in, make decisions about and communicate within legal process intersect with the complexity and severity of charges. Courts are required to make a nuanced analysis of multiple and complex factors, merging medical and legal expertise into decisions made. We explore the nature of FASD and its implications for criminal justice in NZ. The legal and clinical issues in relation to fitness and FASD will be discussed.

Visual perception problems and quality of life in young adults with foetal alcohol spectrum disorders

PURPOSE

To investigate visual perception problems (VPPs), health-related quality of life (HRQoL) and vision-related quality of life (VRQoL) in young adults with foetal alcohol spectrum disorders (FASD) and to compare the results with healthy controls.

METHODS

Thirty young adults with FASD (13 female; mean age 23 years) and 29 controls (20 female; mean age 25 years) participated. Five areas of VPPs were assessed by a structured history-taking. In the FASD group, VPPs were investigated both in childhood (mean age 8 years) and in early adulthood in a prospective follow-up. Health-related quality of life (HRQoL) was investigated with the Pediatric Quality of Life Inventory™ (PedsQL) and VRQoL with the 25-item Visual Function Questionnaire (VFQ-25).

RESULTS

Visual perception problems (VPPs) in at least one area were reported by 16/30 FASD participants (53%) and 1/29 controls (3%) (p = 0.0001, Fisher's exact test), with a similar rate in the same individuals in childhood as in early adulthood (8/27 and 15/27, respectively p = 0.09, McNemar's test). PedsQL total score was lower in the FASD group (n = 20; median: 83; 95% confidence interval (CI) 76-88) compared with controls (n = 29; median: 91; 95% CI 90-95; p = 0.0001, Mann-Whitney U-test). VFQ-25 subscale general vision indicated lower VRQoL in the young adults with FASD (n = 19; median: 80; 95% CI 80-100) compared with controls (n = 29; median: 100; 95% CI 100-100; p = 0.003).

CONCLUSION

Young adults with FASD in the present study had more VPPs and worse VRQoL and HRQoL than healthy controls. In the FASD group, VPPs were reported in childhood as well as in early adulthood.

Caregivers' experiences and perceptions of suicidality among their children and youth with fetal alcohol spectrum disorder

Individuals with Fetal Alcohol Spectrum Disorder (FASD) experience a range of biopsychosocial vulnerabilities that can increase the possibility of adverse life outcomes, including a heightened risk of suicidality. In this study, we explored the lived experiences of caregivers of children and youth with FASD and suicidality, including their perceptions of their child and youth's suicidal experiences. Between March and June 2021, six comprehensive, semi-structured interviews were conducted with five caregivers of children and youth with FASD (Mage = 14.5 years, range 11-22) who were currently experiencing suicidality or had a history of suicidality. Data were analyzed using interpretative phenomenological analysis and then developed into a composite vignette informed and organized by the social-ecological suicide prevention model (SESPM). The composite vignette revealed the narratives of families living with and caring for children and youth with FASD who experience suicidality in relation to the complex and intersectional individual, relational, community, and societal level contextual and protective factors. Findings from this study highlight the critical need for comprehensive FASD-informed suicide prevention and intervention approaches to promote the mental health and wellbeing of children and youth with FASD and their caregivers.

The FASD Eye Code: a complementary diagnostic tool in fetal alcohol spectrum disorders

Objective

To create an easy-to-use complementary ophthalmological tool to support a fetal alcohol spectrum disorder (FASD) diagnosis.

Methods and Analysis

The FASD Eye Code was derived from 37 children with FASD evaluated along with 65 healthy age-matched and sex-matched controls. Four ophthalmological categories, which are abnormalities commonly found in children with FASD, were ranked independently on a 4-point scale, with 1 reflecting normal finding and 4 a strong presence of an abnormality: visual acuity, refraction, strabismus/binocular function and ocular structural abnormalities. The tool was validated on 33 children with attention deficit/hyperactivity disorder (ADHD), 57 children born moderate-to-late premature (MLP) and 16 children with Silver-Russell syndrome (SRS). Among children with ADHD none was born prematurely or small for gestational age (SGA) or diagnosed with FASD. Among children born MLP none was SGA, had a diagnosis of ADHD or FASD, or a history of retinopathy of prematurity. Children with SRS were all born SGA, half were born preterm and none had FASD. Children with FASD were re-examined as young adults.

Results

An FASD Eye Code cut-off total score of ≥10 showed an area under the curve (AUC) of 0.78 (95% CI 0.69 to 0.87), with 94% specificity and 43% sensitivity, in discriminating between FASD and controls, MLP and ADHD, corresponding to a positive likelihood ratio (LR+) of 7.5. Between FASD and controls, an AUC of 0.87 (CI 0.80 to 0.95), with 100% specificity and 43% sensitivity, was found; between FASD and SRS, an AUC of 0.60 (CI 0.45 to 0.75) was found, with 88% specificity and 43% sensitivity. A cut-off score of≥9 showed a specificity of 98% and a sensitivity of 57% for FASD versus controls, corresponding to an LR+ of 36.9. Scores in individuals with FASD were stable into young adulthood.

Conclusion

The FASD Eye Code has the potential to serve as a complementary tool and help to strengthen an FASD diagnosis.

Anthropometrics of Estonian children in relation to family disruption: Thrifty phenotype and Trivers-Willard effects

Background and objectives

The thrifty phenotype hypothesis proposes that at resource limitation, the growth of some organs/tissues is selectively spared to preserve more critical ones, such as the brain or lungs. The Trivers–Willard hypothesis (TWH) predicts that boys are more vulnerable in the case of resource limitation than girls. Both hypotheses were tested in children from disrupted families, differing in the extent of deprivation/adversities imposed on them.

Methodology

In a retrospective cohort study in the mid-20th century Estonia (Juhan Aul’s database), different types of orphans and children of divorced parents (treatment groups; n = 106–1401) were compared with children from bi-parental families (control groups; n = 2548–8648) so that children from treatment groups were matched with control children on the basis of sex, age, year of birth, urban versus rural origin and socioeconomic position.

Results

Children in orphanages suffered strong growth suppression, best explained by psychosocial deprivation. Their feet were on average 0.5 SD shorter than the feet of the controls, followed by height, leg/torso ratio and cranial volume that differed from controls by ca 0.4 SD. Weight difference was 0.2 SD units, while body mass index did not differ from controls. The growth of boys and girls in orphanages was suppressed to the same extent. Boys whose mothers were dead were relatively smaller and less masculine than girls from such families. Fathers’ absence was unrelated to growth suppression. Sons of divorced parents had broader shoulders than boys whose fathers were dead.

Conclusions and implications

Prediction of TWH about the greater vulnerability of male growth may hold under some conditions but not universally. Predictions of the thrifty phenotype hypothesis were partly supported: trunk growth was spared at the expense of leg growth; however, no evidence for brain sparing was found. Comparison of children of divorced versus dead fathers may appear useful for indirect assessment of sexual selection on offspring quality.

Lay Summary: Boys and girls in orphanages suffered similarly strong growth suppression, best explained by psychosocial deprivation. Boys whose mothers were dead were relatively smaller and less masculine than girls from such families. The occurrence of sex-specific associations between family structure and children’s growth depends on the type of family disruption.

Neurocognitive and behavioral profile of fetal alcohol spectrum disorder

Prenatal alcohol exposure is the leading preventable cause of cognitive deficit in developed countries and can lead to fetal alcohol spectrum disorder (FASD). This term encompasses a wide range of physical, mental, behavioral, and cognitive effects that result from damage caused by exposure to alcohol during intrauterine life. Alcohol consumption among the general population is common in Eastern European countries and especially among women at risk of social exclusion, who are the ones who lose or give up custody of their children. A high number of these children are adopted in Spain and many of them present neurocognitive and behavioral disorders, causing FASD to be a public health problem in our country. In many occasions this clinical spectrum is delayed or under-diagnosed due to the overlapping of neuropsychological symptoms caused by the abandonment. A neurocognitive and behavioral profile specific for FASD has not been defined and all the symptoms are common to other etiologies. The aim of this work is to review the neuropsychological profile in the diagnosis of FASD.

Prevalence of Fetal Alcohol Spectrum Disorders (FASD) among Children Adopted from Eastern European Countries: Russia and Ukraine

Fetal alcohol spectrum disorder (FASD) is a leading cause of neurodevelopmental disorders. Children adopted internationally from countries where alcohol consumption during pregnancy is very high are at greater risk for FASD. Lack of expertise in diagnosing FASD and mixed neurodevelopmental and behavioral signs due to abandonment complicate a timely diagnosis. The aim of this study was to determine the prevalence of FASD in adopted children. Children between the ages of 8 and 24 adopted from Russia and Ukraine were evaluated for clinical and historical features of FASD. Of the 162 children evaluated, 81 (50%) met FASD diagnostic criteria. Thirty-three (20.4%) children had fetal alcohol syndrome (FAS), 28 (17.2%) had partial FAS, 2 (1.2%) had alcohol-related birth defects (ARBD) and 18 (11.1%) had alcohol-related neurodevelopmental disorder (ARND). Of the 81 children in which fetal alcohol exposure could not be confirmed, many had manifestations that would have established a diagnosis of FASD if a history of maternal alcohol consumption was confirmed. In a population of children with a high risk of prenatal alcohol exposure (adoptees from Eastern European countries), at least 50% showed manifestations associated with FASD. The reported prevalence in this study is in line with the results obtained in a previous study as well as in orphanages of origin.

Characterizing adverse childhood experiences among children and adolescents with prenatal alcohol exposure and Fetal Alcohol Spectrum Disorder

BACKGROUND

Individuals with Fetal Alcohol Spectrum Disorder (FASD) and prenatal alcohol exposure (PAE) face elevated rates of postnatal environmental adversity across the lifespan.

OBJECTIVE

We explored early adversity among children and adolescents with PAE.

PARTICIPANTS AND SETTING

Our sample included 333 children and adolescents with PAE assessed at a Canadian FASD diagnostic clinic, 66% of whom were diagnosed with FASD.

METHODS

Data were collected retrospectively via record review, and adversity was measured using the Adverse Childhood Experiences Questionnaire (ACE-Q).

RESULTS

Participants experienced high levels of adversity (mean ACE score of 3.4), which increased with age, mental health comorbidity, and number of living placements. Common ACEs included: not being raised by both biological parents (97.3%), caregiver disruption (88.5%), and exposure to household substance use (69.7%). Females had significantly higher rates of sexual abuse than males (p < .001, ø = -0.18). There was no difference in total ACE scores between participants diagnosed with FASD versus those not diagnosed, but participants with FASD were less likely to live with both biological parents (p < .001, ø = .19) or to have been exposed to household mental health problems (p = .007, ø = -0.15).

CONCLUSIONS

Children and adolescents with PAE experience high rates of early adversity. Practice and policy initiatives are needed to improve early detection of ACEs among children with PAE, and of PAE among children with ACEs. Targeted supports are needed to strengthen the early caregiving environment and mitigate the risks of adversity to support healthy outcomes for individuals with PAE and FASD.

A Systematic Review of Interventions to Improve Mental Health and Substance Use Outcomes for Individuals with Prenatal Alcohol Exposure and Fetal Alcohol Spectrum Disorder

Individuals with fetal alcohol spectrum disorder (FASD) experience remarkably high rates of mental health and substance use challenges, beginning early in life and extending throughout adulthood. Proactive intervention can help to mitigate some of these negative experiences. Although the literature on FASD intervention is growing, there is currently a lack of consolidated evidence on interventions that may improve mental health and substance use outcomes in this population. Informed by a life course perspective, we undertook a systematic review of the literature to identify interventions that improve mental wellness through all developmental stages for people with prenatal alcohol exposure (PAE) and FASD. A total of 33 articles were identified, most of which were focused on building skills or strategies that underlie the well‐being of children with PAE and FASD and their families. Other interventions were geared toward supporting child and family wellness and responding to risk or reducing harm. There was a notable lack of interventions that directly targeted mental health and substance use challenges, and a major gap was also noted in terms of interventions for adolescents and adults. Combined, these studies provide preliminary and emerging evidence for a range of intervention approaches that may support positive outcomes for individuals with FASD across the life course.

Alcohol use in pregnancy and its impact on the mother and child

AIMS

To review the impact of prenatal alcohol exposure on the outcomes of the mother and child.

DESIGN

Narrative review.

SETTING

Review of literature.

PARTICIPANTS

Mothers and infants affected by prenatal alcohol use.

MEASUREMENTS

Outcomes of mothers and children.

FINDINGS

Prenatal alcohol exposure is one of the most important causes of preventable cognitive impairment in the world. The developing neurological system is exquisitely sensitive to harm from alcohol and there is now also substantial evidence that alcohol-related harm can extend beyond the individual person, leading to epigenetic changes and intergenerational vulnerability and disadvantage. There is no known safe level or timing of drinking for pregnant or lactating women and binge drinking (> four drinks within 2 hours for women) is the most harmful. Alcohol-exposure increases the risk of congenital problems, including Fetal Alcohol Spectrum Disorder (FASD) and its most severe form, Fetal Alcohol Syndrome (FAS).

CONCLUSION

The impact of FASD and FAS is enduring and life-long with no current treatment or cure. Emerging therapeutic options may mitigate the worst impact of alcohol exposure but significant knowledge gaps remain. This review discusses the history, epidemiology and clinical presentations of prenatal alcohol exposure, focusing on FASD and FAS, and the impact of evidence on future research, practice and policy directions.

Thinner retinal nerve fibre layer in young adults with foetal alcohol spectrum disorders

BACKGROUND/AIMS

Ophthalmological abnormalities such as ptosis, strabismus, refractive errors and optic nerve hypoplasia have been reported in foetal alcohol spectrum disorders (FASD). The purpose of this study was to investigate whether retinal thickness, retinal nerve fibre layer (RNFL) and optic disc area (ODA) differ between individuals with FASD and healthy controls.

METHODS

Best-corrected visual acuity (BCVA) in terms of logarithm of the minimum angle of resolution (logMAR), refraction, and fundus variables measured by optical coherence tomography were obtained from 26 young adults with FASD (12 women, median age 23 years) and 27 controls (18 women, median age 25 years).

RESULTS

The total thickness of the peripapillary RNFL was significantly lower in the FASD group than in controls; median (range) in the right/left eye was 96.5 (60-109)/96 (59-107) µm in the FASD group and 105 (95-117)/103 (91-120) µm among controls (p=0.001 and p=0.0001). Macular RNFL and retinal thickness measurements from the FASD group were also lower in most of the nine ETDRS areas, except for the central parts. Median (range) BCVA in the best eye was 0.00 (-0.1-0.3) logMAR in the FASD group and 0.00 (-0.2-0.0) logMAR in controls (p=0.001). No significant differences between the groups were found regarding ODA or refraction.

CONCLUSION

Significant differences in peripapillary and macular RNFL, retinal thickness and BCVA were found in this group of young adults with FASD compared with healthy controls. However, there were no differences in the size of the optic disc.

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.
