“…Studies included children with a range of motor and visual impairments (ocular and cerebral). Many of the included studies recruited participants from sites providing services to children known or suspected to have visual impairments, such as from vision clinics …”

“…The Functional Visual Questionnaire, Visual Assessment Procedure – Capacity, Attention and Processing, and Visual Skills Inventory used factor analysis and principal components analysis to confirm dimensionality; however, these factors were not incorporated into the scoring schema or used to aid interpretability of the measures. Internal consistency, test–retest, or interrater reliability were reported for six measures . Clinicians in reliability studies for the CVI Range and Erhardt Developmental Visual Assessment had undergone training programmes in the administration and scoring of the measure, before testing.…”

“…The methodological quality of 10 studies reporting psychometric properties was evaluated using the COSMIN . The results of this analysis can be found in Table SIII (online supporting information).…”

“…Finally, measures included in this review with evidence of construct validity relied heavily on correlations with, or discrimination from, Body Functions or Impairment‐level measures . This was done in the absence of specific hypotheses for evidence of construct validity.…”

A pilot study regarding basic knowledge of “cortical visual impairment in children” among ophthalmologists

“…Similarly, we searched the PubMed with the keywords “knowledge” and “CVI” and “ophthalmologist.” This search retrieved 8 articles, but none of them was related to the assessment of knowledge among ophthalmologists. [ 10 15 16 17 18 19 20 21 ]…”
