Editors Keywords: visual impairment children rehabilitation review functioning participation a b s t r a c t Visual impairment in childhood often has life-long implications. To aim for the highest levels of functioning, participation, and quality of life and to ensure children's well-being, children should be entitled to the most effective rehabilitation programs. We review evidence for the effectiveness of rehabilitation interventions for children with visual impairment to improve skills and behavior, thereby improving participation and quality of life as an ultimate goal. Of the 441 potentially relevant articles identified, 66 studies met our inclusion criteria (i.e., 28 randomized controlled trials, 18 nonrandomized controlled trials, and 20 before-after comparisons). The results suggest that sports camps, prescription and training in the use of low vision devices, and oral hygiene programs might be effective in improving functioning and elements of participation and quality of life in children with visual impairment. Other interventions showed mixed or negative results. The results should be interpreted with caution because of moderate to high risk of bias and suboptimal reporting. Heterogeneity of results and the use of over 50 different outcome measures prevented a meta-analysis. Future studies should focus on promising interventions for which effectiveness is still unclear (e.g., mobility, social skills), with adequately designed methodology.

Background The prevalence of visual impairments in people with severe and profound multiple disabilities (SPMD) is the subject of considerable debate and is difficult to assess. Methods In a typical Dutch care organization, all clients with SPMD ( n =  ) participated in the study and specific instruments adapted to these clients (requiring a minimum of cooperation) were used to measure visual acuity, the visual field, binocular vision, contrast sensitivity, refractive errors and visual functioning behaviour. Results We found an unexpected  % of clients with SPMD to have visual impairments. Previously, only  % were known to have visual problems. None of the persons observed had normal visual acuity. Subnormal visual acuity was the best result. The severity of the visual impairment was related to the severity of the intellectual disability. In addition to the problem of acuity, impairments in the visual field, impaired contrast sensibility and impaired binocular functioning were found, as well as impaired visual attention, fixation and following. In  % of the

Secure parent-child attachment may help children to overcome the challenges of growing up with a visual or visual-and-intellectual impairment. A large literature exists that provides a blueprint for interventions that promote parental sensitivity and secure attachment. The Video-feedback Intervention to promote Positive Parenting (VIPP) is based on that blueprint. While it has been adapted to several specific at risk populations, children with visual impairment may require additional adjustments. This study aimed to identify the themes that should be addressed in adapting VIPP and similar interventions. A Delphi-consultation was conducted with 13 professionals in the field of visual impairment to select the themes for relationship-focused intervention. These themes informed a systematic literature search. Interaction, intersubjectivity, joint attention, exploration, play and specific behavior were the themes mentioned in the Delphi-group. Paired with visual impairment or vision disorders, infants or young children (and their parents) the search yielded 74 articles, making the six themes for intervention adaptation more specific and concrete. The rich literature on six visual impairment specific themes was dominated by the themes interaction, intersubjectivity, and joint attention. These themes need to be addressed in adapting intervention programs developed for other populations, such as VIPP which currently focuses on higher order constructs of sensitivity and attachment.
