Abstract
BACKGROUND Retinoscopy is arguably the most important method in the eye clinic for diagnosing and managing refractive errors. Advantages of retinoscopy include its non-invasive nature, ability to assess patients of all ages, and usefulness in patients with limited cooperation or communication skills.
AIM To discuss the history of retinoscopes and examine current literature on the subject.
METHODS A search was conducted on the PubMed and with the reference citation analysis (https://www.referencecitationanalysis.com) database using the term “Retinoscopy,” with a range restricted to the last 10 years (2013-2023). The search string algorithm was: "Retinoscopy" (MeSH Terms) OR "Retinoscopy" (All Fields) OR "Retinoscopes" (All Fields) AND [(All Fields) AND 2013: 2023 (pdat)].
RESULTS This systematic review included a total of 286 records. Publications reviewed iterations of the retinoscope into autorefractors, infrared photo retinoscope, television retinoscopy, and the Wifi enabled digital retinoscope.
CONCLUSION The retinoscope has evolved significantly since its discovery, with a significant improvement in its diagnostic capabilities. While it has advantages such as non-invasiveness and broad applicability, limitations exist, and the need for skilled interpretation remains. With ongoing research, including the integration of artificial intelligence, retinoscopy is expected to continue advancing and playing a vital role in eye care.

Nutritional blindness from avoidant-restrictive food intake disorder - recommendations for the early diagnosis and multidisciplinary management of children at risk from restrictive eating. Arch Dis Child 2024; 109:181-187. [PMID: 37414514 DOI: 10.1136/archdischild-2022-325189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Accepted: 06/15/2023] [Indexed: 07/08/2023]
Abstract
Avoidant-restrictive food intake disorder (ARFID) is an eating disorder characterised by limited consumption or the avoidance of certain foods, leading to the persistent failure to meet the individual's nutritional and/or energy needs. The disordered eating is not explained by the lack of available food or cultural beliefs. ARFID is often associated with a heightened sensitivity to the sensory features of different types of food and may be more prevalent among children with autism spectrum disorder (ASD) for this reason. Sight loss from malnutrition is one of the most devastating and life-changing complications of ARFID, but difficult to diagnose in young children and those with ASD who have more difficulty with communicating their visual problems to carers and clinicians, leading to delayed treatment and greater probability of irreversible vision loss. In this article, we highlight the importance of diet and nutrition to vision and the diagnostic and therapeutic challenges that clinicians and families may face in looking after children with ARFID who are at risk of sight loss. We recommend a scaled multidisciplinary approach to the early identification, investigation, referral and management of children at risk of nutritional blindness from ARFID.

Abstract
Purpose Autistic people face significant barriers when accessing healthcare services. Eye examinations present unique challenges. Accessibility of this healthcare sector for autistic people has not been investigated previously. The aim of this research was to investigate eye examination accessibility for autistic adults and produce recommendations for autism‐friendly eyecare. Methods Two qualitative studies were conducted. In Study 1, 18 autistic adults took part in focus groups to elicit their eye examination experiences. Transcripts of the recorded discussions were thematically analysed. Study 1 findings were used to design autism‐friendly eye examinations for autistic adults. These were conducted in Study 2. Twenty‐four autistic adults participated in these examinations, during which they were interviewed about their experience and how it might be improved by reasonable modifications. Audio recordings of the interviews were content analysed. Results Knowledge of what to expect, in advance of the eye examination, could greatly reduce anxiety. Participants liked the logical structure of the examination, and the interesting instrumentation used. However, the examination and practice environment did include sensory challenges, due to lights, sound and touch. Changes in practice layout, and interacting with multiple staff members, was anxiety provoking. Participants expressed a need for thorough explanations from the optometrist that outlined the significance of each test, and what the patient was expected to do. Conclusion A number of accessiblity barriers were identified. These suggested that UK eye examinations are not very accessible for autistic adults. Barriers began at the point of booking the appointment and continued through to the dispensing of spectacles. These caused anxiety and stress for this population, but could be reduced with easy‐to‐implement adaptations. Based on the findings, recommendations are presented here for the whole eyecare team which suggest how more autism‐friendly eye examinations can be provided.

Abstract
SIGNIFICANCE Clinicians can better diagnose and manage vision problems of autism spectrum disorder (ASD) children by establishing a standard of care for this population. Results also reinforce the importance of a comprehensive binocular vision evaluation in all patients with ASD. PURPOSE The purposes of this study were to compare near-point and ocular motility test findings in ASD children and typically developing (TD) peers and to compare findings among ASD children by level of verbal communication. METHODS Sixty-one children and adolescents (ASD, 34; TD, 27) aged 9 to 17 years completed an eye examination protocol including tests of distance and near phoria, near point of convergence, near fusional convergence and divergence, accommodative response, and Northeastern State University College of Optometry oculomotor testing. Testing was completed through refractive correction. Parents of ASD children provided information regarding subjects' verbal communication level (nonverbal, uses short words, verbal). RESULTS Distance phoria did not differ significantly between groups. Near phoria of ASD subjects was more exophoric (difference, 2.8 prism diopters). Mean near point of convergence break and recovery were 7.0 and 8.02 cm, respectively, in ASD subjects and 2.19 and 3.99 cm in TD subjects. Near fusional divergence and convergence showed no significant difference. Autism spectrum disorder subjects had significantly poorer stereoacuity (P < .0001) and, on Northeastern State University College of Optometry Oculomotor Testing, reduced fixation, poorer accuracy and stamina/ability, and increased head and body movement. Monocular estimation method retinoscopy results did not differ significantly between ASD and TD subjects. No significant differences in phoria, near point of convergence, and near fusional divergence or convergence were observed between ASD subgroups (nonverbal, uses short words, verbal). CONCLUSIONS Autism spectrum disorder children are more likely to show receded near point of convergence, poor fixation, inaccurate saccades, erratic pursuits, and exophoric posture. These differences occur, regardless of reported verbal communication level.

Abstract
SIGNIFICANCE Vision problems occur at higher rates in children with autism spectrum disorder (ASD) than in the general population. Some professional organizations recommend that children with neurodevelopmental disorders need comprehensive assessment by eye care professionals rather than vision screening. METHODS Data from the 2011 to 2012 National Survey of Children's Health (NSCH) were accessed. Logistic regression was used to evaluate differences between vision screening rates in eye care professionals' offices and other screening locations among children with and without ASD. RESULTS Overall, 82.21% (95% confidence interval [CI], 78.35 to 86.06%) of children with ASD were reported to have had a vision screening as defined by the NSCH criteria. Among children younger than 5 years with ASD, 8.87% (95% CI, 1.27 to 16.5%) had a vision screening at a pediatrician's office, 41.1% (95% CI, 20.54 to 61.70%) were screened at school, and 37.62% (95% CI, 9.80 to 55.45%) were examined by an eye care professionals. Among children with ASD older than 5 years, 24.84% (95% CI, 18.42 to 31.26%) were screened at school, 22.24% (95% CI, 17.26 to 27.21%) were screened at the pediatricians' office, and 50.15% (95% CI, 44.22 to 56.08%) were examined by eye care professionals. Based on estimates from NSCH, no children in the U.S. population younger than 5 years with ASD screened in a pediatrician's office were also seen by an eye care provider. CONCLUSIONS If the public health goal is to have all children with ASD assessed in an eye care professional's office, data from the NSCH indicate that we as a nation are falling far short of that target.

Abstract
PURPOSE Eye pathology could be related to atypical visual behaviours and impaired social communication through visual cues in children with autism spectrum disorder (ASD). The main purpose of this prospective study was to assess ophthalmological disorders in children with ASD and to investigate the relationships with intellectual disability (ID) and ASD severity. METHODS In this prospective study, comprehensive ophthalmological and oculomotor examinations were performed. ASD severity and verbal and performance intelligence quotients were determined using adapted scales. These clinical data were compared between groups of children based on the presence or absence of ophthalmological disorders and the achievement or not of visual acuity (VA) testing by using non-parametric statistical tests. RESULTS Amongst a sample of 51 children, ophthalmological disorders were found in 39% of cases, with 35% having significant refractive errors and 10% presenting with strabismus. Children with ASD and ophthalmological disorders had significantly lower verbal (29.8 ± 14.7 compared with 44.3 ± 21.5; p = 0.010) and performance quotients (57.8 ± 18.3 compared with 67.59 ± 20; p = 0.049) but no significant result was found between the presence of ophthalmological disorders and ASD severity, level of communication and social contact, or modulating behaviour when changes occur. Children who did not achieve monocular VA testing (39%) had significantly lower verbal (25.1 ± 9.7 compared with 46.1 ± 20.9; p < 0.001) and performance quotients (52.7 ± 17 compared with 69.8 ± 18.8; p = 0.001), also presented higher social interaction impairment (p = 0.002), and expressed more important behavioural signs (p = 0.007). CONCLUSIONS Ophthalmological disorders are frequently found in children with ASD, especially in those with ID. Ophthalmologists and child psychiatrists should pay attention to perform ophthalmological examination in children with ASD since eye disorders might remain undetected. A comprehensive examination by a paediatric ophthalmologist would help to improve the individual clinical description and the global intervention.

Abstract
PURPOSE To evaluate the ability of the PDI Check (PDI Check LLC, Anchorage, AK) near vision screening game to assess monocular acuity, stereopsis, suppression, and color. METHODS Children and adults consented to perform the PDI Check Quick Screening game following conventional near testing of patched Rosenbaum acuity, Titmus Fly stereo, Worth 4-dot, and Ishihara color. Time to complete each test and preferred method were recorded. RESULTS A total of 77 patients (5 to 63 years old) attempted all tests. There was a positive correlation between the PDI Check and conventional tests for all visual tasks. Using previously determined instrument referral criteria, sensitivity/specificity was determined for right acuity (67%/91%), left acuity (55%/94%), stereopsis (87%/95%), red-green color (80%/99%), and ocular suppression (58%/98%). Screening time was 202 ± 96 versus 99 ± 42 seconds for the PDI Check and the game was preferred by 87%. CONCLUSIONS The PDI Check provided a valid assessment of near vision in less than half the time of conventional testing without patches or goggles. This Quick Screening version may help eye technicians and physicians with time efficiency in the frequent task of near visual assessment. [J Pediatr Ophthalmol Strabismus. 2019;56(4):234-237.].

Abstract
PURPOSE To assess functional vision in children with autism spectrum disorder (ASD) with a cognitive visual function battery in addition to standard ophthalmic examinations. METHODS Subjects were recruited from a school for children with ASD. In addition to a comprehensive ophthalmic examination, all children underwent cognitive vision assessment at a tertiary ophthalmological care center in India. RESULTS A total of 30 children were included. The distribution of the number of children with mild to moderate versus severe ASD was nearly equal based on CARS autism scores. The majority of subjects had normal color vision (16/18), contrast (24), shape discrimination (26), and perception of directionality (28). Most were not able to identify optical illusions or differentiate tests of emotions. Ocular pursuits, saccades, and recognition of size differences were often abnormal. Poor visual closure was noted in (11) subjects. The duration of fixation to Heidi face target was inversely proportional to the severity of ASD. The study further established that cognitive visual impairment was present in children with ASD irrespective of their severity of ASD. CONCLUSIONS All subjects had some form of cognitive visual impairment independent of ASD severity.

Abstract
Autism spectrum disorder (ASD) is a common neurodevelopmental condition with approximately 1-2 per cent prevalence in the population. The condition has lifelong effects for the individual and family, and early intervention and management helps maximise quality of life and outcomes. Many studies of vision in ASD have attempted to link the behavioural and sensory deficits in ASD with underlying visual processing. From this work, it is clear that individuals with ASD 'see' and process the world differently, but there remain gaps in our understanding. This review will summarise our current knowledge of key aspects of visual functions and the optometric profile of ASD. This includes findings regarding visual acuity and contrast sensitivity, refractive error, eye movements, binocular vision, near visual functions and retinal structure in ASD. From this, a pattern of knowledge emerges for children with ASD: we should expect normal visual acuity; there will likely be atypical eye movements and susceptibility for subtle visuo-motor deficits, there is an increased prevalence of strabismus; an increased likelihood of astigmatism and possibly other refractive errors; attention, crowding and task complexity will likely be problematic; and retinal structure and function may be compromised. Bringing this together, these findings highlight that further work is necessary, not only to understand how higher-level functions link to behaviours, but also to ensure there is a sound understanding of the building-blocks of vision to fully grasp the profile of visual processing as a whole in ASD. This review will give a translational viewpoint for clinicians, and underline the benefits of comprehensive vision care in ASD.

Abstract
Studies have shown considerable evidence of visual dysfunction in autism spectrum disorders. Anomalies in visual information processing can have a major effect on the life quality of individuals with autism spectrum disorders. We summarise the hypotheses and theories underlying neural aetiologies and genetic factors that cause these disorders, as well as the possible influences of unusual sensory processing on the communications and behaviour characterised by the autistics. In particular, we review the impact of these dysfunctions on visual performance.

Abstract
Anomalous visual processing has been described in individuals with autism spectrum disorder (ASD) but relatively few studies have profiled visual acuity (VA) in this population. The present study describes presenting VA in children with ASD (n = 113) compared to typically developing controls (n = 206) and best corrected visual acuity (BCVA) in a sub-group of children with ASD (n = 29). There was no statistically significant difference in presenting VA between groups (z = -1.75, p = 0.08); ASD group median VA (interquartile range, IQR) -0.05 logMAR (IQR: -0.125 to 0.025 logMAR) and typically developing control group -0.075 logMAR (IQR: -0.150 to -0.025 logMAR). Median BCVA was -0.175 logMAR (IQR: -0.200 to -0.125 logMAR) for the ASD sub-group. Clinicians should not anticipate reduced VA when assessing children with ASD.

Abstract
Children with autism spectrum disorders (ASD) frequently have ophthalmologic disorders. Due to poor cooperation with ophthalmological examination, ocular abnormalities in such children may be overlooked. We retrospectively studied the records of 324 patients diagnosed as ASD that underwent ophthalmological examination between January 2011 and November 2014 at Dr. Sami Ulus Maternity and Children Research and Training Hospital, Ankara, Turkey. Ophthalmic pathology was noted in 26.9% of patients with ASD, of which 22% had significant refractive errors and 8.6% had strabismus. Comprehensive eye examination by a pediatric ophthalmologist is recommended for all children diagnosed as ASD.

Abstract
OBJECTIVES To determine detailed oculo-visual characteristics of children with intellectual disability studying in special schools and explore the burden of visual impairment. DESIGN OF THE STUDY Detailed ophthalmic examination was carried out in all pupils studying at the seven special needs schools of Kathmandu valley, Nepal. Ophthalmic examination included case history, presenting distance visual acuity, cycloplegic refraction, binocular vision examination, contrast sensitivity and anterior and posterior segment evaluation. MAIN OUTCOME MEASURES Ocular and visual status of children. RESULTS Refractive errors (40%) and strabismus (17%) were the commonest visual disorders in our study children. Ninety-five per cent of the children who had clinically significant refractive errors presented without any correction. Visual impairment was present in 25% of the children. Severe visual impairment or worse was present in 3% of the children. Other common ocular findings were conjunctivitis, blepharitis, chalazion and ectropion. CONCLUSIONS High prevalence of preventable visual impairment in this population requires immediate attention. It is hoped that the formulation of proper vision care guidelines at a national level may help in early detection and management of visual disorders in this special population and enhance their quality of life.
