Screen-based methods for measuring acuity in young children using a preferential-looking paradigm have also been trialed and have shown high correlation with gold-standard clinic measures.…”

Background. Cerebral Visual Impairment (CVI) is the most common cause of low vision in children. Standardized, quantifiable measures of visual function are needed. Objective. This study developed and evaluated a new method for quantifying visual function in young and medically complex children with CVI using remote videoconferencing. Methods. Children diagnosed with CVI who had been unable to complete clinic-based recognition acuity tests were recruited from a low-vision rehabilitation clinic(n=22)Video-based Visual Function Assessment (VFA) was implemented using videoconference technology. Three low-vision rehabilitation clinicians independently scored recordings of each childs VFA. Interclass correlations for inter-rater reliability was analyzed using intraclass correlations (ICC). Correlations were estimated between the video-based VFA scores and both clinically obtained acuity measures and childrens cognitive age equivalence. Results: Inter-rater reliability was analyzed using intraclass correlations (ICC). Correlations were estimated between the VFA scores, clinically obtained acuity measures, and cognitive age equivalence. ICCs showed good agreement (ICC and 95% CI 0.835 (0.701-0.916)) on VFA scores across raters and agreement was comparable to that from previous, similar studies. VFA scores strongly correlated (r= -0.706, p=0.002) with clinically obtained acuity measures. VFA scores and the cognitive age equivalence were moderately correlated (r= 0.518, p=0.005), with notable variation in VFA scores for participants below a ten month cognitive age-equivalence. The variability in VFA scores among children with lowest cognitive age-equivalence may have been an artifact of the studys scoring method, or may represent existent variability in visual function for children with the lowest cognitive age-equivalence. Conclusions: Our new VFA is a reliable, quantitative measure of visual function for young and medically complex children with CVI. Future study of the VFA intrarater reliability and validity is warranted.

“…Higher order visual perceptual functions associated with the dorsal and ventral networks should also be quantitatively investigated. Eye tracking technology may be useful in cases where conventional neuropsychological methods are challenging due to comorbid cognitive and/or communication difficulties (Ben Itzhak et al, 2023; Bennett et al, 2018; Good et al, 1994; Huo et al, 1999; Kooiker et al, 2016; Mayer et al, 2020; Mooney et al, 2021; Tanke et al, 2021). Additionally, screening for infants and toddlers at risk for CVI needs to be implemented as early as possible with follow up and monitoring over time.…”

Cerebral visual impairment (CVI) is a leading cause of pediatric visual impairment worldwide. Despite the ramifications on multiple developmental domains and quality of life factors, substantial barriers remain for evaluation, diagnosis, treatment, and education of this growing population of children and adults. At the root is a lack of consensus on the definition and diagnostic criteria of CVI and a narrow ocular/acuity-based classification of visual impairment. This article covers four main issues that need to be urgently addressed to make strides toward removing current barriers. These challenges highlight the need for policy change at multiple levels to help ensure that individuals with CVI will have access to appropriate (re)habilitation and education services regardless of their acuity or visual function. Suggested solutions include the implementation of a globally accepted definition of CVI and increased multidisciplinary training programs. These will support international efforts to develop and implement quantitative interdisciplinary assessment methods, identify meaningful and effective intervention approaches, and monitor long-term outcomes for those with CVI. Additionally, sensitive and specific markers can be identified for differentiating CVI from other related developmental conditions, such as autism spectrum disorder and developmental coordination disorder. Ultimately, these proposed changes will lead toward improved quality of life for individuals with CVI and their caregivers.
