“…Also, the use of several other neuropsychological (sub)tests have been studied, but evidence for the diagnostic value of individual tests is lacking and most tests seem involved in multiple visual perceptive dimensions ( Ben Itzhak et al, 2021b ). Since performance differences on the DVTP were found between American and Asian children ( Chan and Chow, 2005 ; Cheung et al, 2005 ), adaptation of normative data to local populations seems required. In addition, disorders in visual organization, in recognition in reduced circumstances and recognition in noise are likely typical disorders of visual processing in CVI ( Stiers et al, 2001 ).…”

IntroductionCerebral visual impairment (CVI) is an important cause of visual impairment in western countries. Perinatal hypoxic-ischemic damage is the most frequent cause of CVI but CVI can also be the result of a genetic disorder. The majority of children with CVI have cerebral palsy and/or developmental delay. Early diagnosis is crucial; however, there is a need for consensus on evidence based diagnostic tools and referral criteria. The aim of this study is to develop guidelines for diagnosis and referral in CVI according to the grade method.Patients and MethodsWe developed the guidelines according to the GRADE method 5 searches on CVI (children, developmental age ≤ 18 years) were performed in the databases Medline, Embase, and Psychinfo, each with a distinct topic.ResultsBased on evidence articles were selected on five topics: 1. Medical history and CVI-questionnaires 23 (out of 1,007). 2. Ophthalmological and orthoptic assessment 37 (out of 816). 3. Neuropsychological assessment 5 (out of 716). 4. Neuroradiological evaluation and magnetic resonance imaging (MRI) 9 (out of 723). 5. Genetic assessment 5 (out of 458).ConclusionIn medical history taking, prematurity low birth weight and APGAR (Appearance, Pulse, Grimace, Activity, Respiration) Scores (<5) are important. Different questionnaires are advised for children under the age of 3 years, older children and for specific risk groups (extremely preterm). In ophthalmological examination, eye movements, specially saccades, accommodation, crowding, contrast sensitivity and visual fields should be evaluated. OCT can show objective signs of trans-synaptic degeneration and abnormalities in fixation and saccades can be measured with eye tracking. Screening of visual perceptive functioning is recommended and can be directive for further assessment. MRI findings in CVI in Cerebral Palsy can be structured in five groups: Brain maldevelopment, white and gray matter lesions, postnatal lesions and a normal MRI. In children with CVI and periventricular leukomalacia, brain lesion severity correlates with visual function impairment. A differentiation can be made between cortical and subcortical damage and related visual function impairment. Additional assessments (neurological or genetic) can be necessary to complete the diagnosis of CVI and/or to reveal the etiology.

“…The DTVP-2 includes a battery of eight subscales that measure different but interrelated motor-reduced visual perceptual and motor-enhanced visual-motor abilities (Brown, Rodger, & Davis, 2008;Cheung, Poon, Leung, & Wong, 2005). The four DTVP-2 subscales that measure visual perceptual abilities with minimal motor involvement are Position-in-Space, FigureeGround, Visual Closure, and Form Constancy (Hammill et al, 1993).…”

Background: Theoretical perspectives vary in considering whether visual perceptual skills and visual-motor integration (VMI) skills are related, interdependent skill sets, or two discrete skill constructs. Objective: This study investigated whether motor-reduced/free visual perceptual skill constructs were predictive of motor-enhanced VMI skill constructs. Method: A total of 45 typically developing children aged 6e12 years completed the Developmental Test of Visual Perception-Second Edition (DTVP-2) and the Test of Visual Perceptual Skills-Third Edition (TVPS-3). Four multiple linear regression analyses were completed with the four DTVP-2 motor-enhanced VMI subscales being the dependent (criterion) variables and the seven TVPS-3 motor-reduced subscales being the independent variables. Results: The total variance accounted for in the four DTVP-2 VMI skill constructs by all the seven TVPS-3 skill constructs ranged from 29.3% to 60.10%. In the first regression analysis, the TVPS-3 Visual Sequential Memory and TVPS-3 Visual FigureeGround constructs explained 5.40% and 4.90%, respectively, of the variance in the DTVP-2 EyeeHand Coordination construct. In the second regression, the TVPS-3 Visual Sequential Memory and TVPS-3 Visual FigureeGround constructs accounted for 5.60% and 3.10%, respectively, of the DTVP-2 Copying construct's variance. The third analysis revealed that the TVPS-3 Visual Memory and TVPS-3 Visual Form Constancy constructs represented 6.20% and 7.90%, respectively, of the DTVP-2 Spatial Relations construct's variance. In the fourth and final regression analysis, the TVPS-3 Visual Sequential Memory and TVPS-3 Visual FigureeGround construct explained 14.60% and 4.90%, respectively, of the variance in the DTVP-2 Visual-Motor Speed construct.

“…There were many local studies on the performance differences in visual perception and fine motor aspects for children in Hong Kong. In the study by Cheung, Poon, Leung, and Wong (2005), it was noted that there was ceiling effect for 6e7-year-old children in EyeeHand Coordination, Position in Space, and Spatial Relations subtests among the eight different subtests of the Developmental Test of Visual Perception Version 2. Chui, Ng, Fong, Lin, and Ng (2007) found that children aged 6e10 years in Hong Kong performed significantly better in the subtests of Visual-Motor Control and Upper Limb Speed and Dexterity in the BruininkseOseretsky Test of Motor Proficiency than those in the United States.…”

KEYWORDSBeeryeBuktenica Developmental Test of Visual-Motor Integration; local reference in Hong Kong; preschool children; Rasch Measurement Model Summary Objective/Background: The BeeryeBuktenica Developmental Test of Visual-Motor Integration (VMI) is an important assessment tool used by occupational therapists working with children. The aims of this study were (a) to identify performance differences in the VMI between Hong Kong preschool children and their counterparts in the United States; (b) to develop local references for the VMI (fifth edition) for the preschool children in Hong Kong; and (c) to examine the dimensionality and the hierarchical ordering of the VMI items using the Rasch Measurement Model (RMM).Methods: A total of 288 healthy children aged between 3 years and 6 months and 5 years and 11 months were recruited from 54 local preschools in Hong Kong using the multistage sampling method. VMI was administered to the children individually at their preschools. Results: Hong Kong preschool children were significantly better than those in the United States in VMI performance (p < .001). The results of the RMM showed that the VMI fell within the acceptable levels of unidimensionality. Most items were found to be hierarchically ordered, although a few items were found to have the same level of difficulty. Conclusion: The local reference developed in this study yielded additional insights for occupational therapists and psychologists with regard to the application of the VMI (fifth edition) for Hong Kong children aged between 3 years and 6 months and 5 years and 11 months.
