“…A previous study, including children with unilateral CP aged between 5 years and 18 years, reported that visual-perceptual functions (measured according to the TVPS-3) did not differ between those with different levels of manual ability (measured according to the MACS). 6 On the contrary, we found a significant difference in visual-perceptual functions (visual figure-ground subtest of the TVPS-4 and the visual perception subtest of the Beery-VMI) between children in MACS levels I and III. The study by Berelowitz and Franzsen 6 included different subtypes of CP, a different age range, and a different version of the TVPS, which might account for the differences from our results.…”

“…This is in contrast with previous studies reporting that children with left-sided unilateral CP showed lower performance compared with right-sided unilateral CP or NTD. 6,7 This was explained by the fact that the right hemisphere of the brain processes visuospatial function. Differences with our findings could be explained by more widespread (bilateral) lesions in our cohort.…”

“…3,[6][7][8][9] Additionally, two studies showed that children with left-sided unilateral CP have worse performance on visual-perceptual tests than children with neurotypical development (NTD) or right-sided unilateral CP. 6,7 Despite the importance of these findings, 3,[6][7][8] sample sizes were relatively small (n < 20) and a comparison group was not included 3,6,8 or not matched. 7 Furthermore, previous studies demonstrated that decreased visual-perceptual abilities affect motor performance 10,11 and quality of life 12 in children with CP, emphasizing the importance of investigating the use of vision in everyday activities (i.e.…”

“…Specifically, cerebral visual impairment (CVI), a ‘verifiable visual dysfunction not attributed to disorders of the anterior visual pathways or any potentially co‐occurring ocular impairment’, 4 is reported in 60% to 70% of children with CP 5 . The prevalence of visual impairments varies depending on the CP subtypes 6 . Particularly, in children with spastic unilateral CP, in whom predominantly one side of the body is affected, 1 previous studies reported on oculomotor impairment, reduction in visual acuity, visual field constrictions and hemianopia, altered stereoacuity, and visual–perceptual functions 3,6–9 .…”

AimTo investigate visual (perceptual) function and functional vision in children with unilateral cerebral palsy (CP) and children with neurotypical development (NTD).MethodFifty children with unilateral CP (mean age 11 years 11 months, SD 2 years 10 months, range 7–15 years; 27 males; 26 left‐sided unilateral CP; Manual Ability Classification System [MACS] levels: I, 27; II, 16; III, 7) and 50 age‐ and sex‐matched children with NTD participated in a cross‐sectional study. Visual acuity, stereoacuity, and visual–perceptual functions were measured with standardized clinical tests. Functional vision was assessed in children with unilateral CP with the Flemish cerebral visual impairment questionnaire (FCVIQ). Group differences were investigated with Mann–Whitney U tests, Kruskal–Wallis tests, and the relative effect sizes r, η2 respectively. Correlations between visual assessments and the FCVIQ were investigated with Spearman's rank correlations.ResultsThe total group of children with unilateral CP showed reduced visual acuity compared with children with NTD (p = 0.02, r = 0.23). Only children with left‐sided unilateral CP scored lower than those with NTD on stereoacuity (p < 0.01, r = 0.36). Children with right/left‐sided unilateral CP scored significantly lower than those with NTD on visual–perceptual functions (p = 0.001–0.02), with large effect sizes on visuomotor integration and visual closure (both r = 0.57). Children with unilateral CP classified in MACS level III showed significantly lower scores on visual–perceptual assessments than children classified in MACS level I. Stereoacuity and visual–perceptual functions negatively correlated with the FCVIQ, with the highest association with visual (dis)interest and anxiety‐related behaviours.InterpretationMulti‐level visual profiling is warranted in the clinical intake of children with unilateral CP to detect visual impairments that further compromise their level of functioning.
