The effectiveness of an individualised and adaptive game-based rehabilitation, iVision, on visual perception in cerebral visual impairment: A triple-blind randomised controlled trial.

Background: Cerebral visual impairment (CVI) can negatively affect a child's functioning, emphasising the need for interventions to improve visual perception (VP), potentially translating into improved health-related quality of life (HRQOL).

Aims: Assessing the effectiveness of an adaptive individualised game-based rehabilitation, iVision, on VP, visual function, functional vision, and HRQOL.

Methods And Procedures: Seventy-three children with CVI (3-12 performance age) were randomised into the adaptive individualised or the non-adaptive non-individualised group (3 sessions/week; 12 weeks).

The relation between visual orienting functions, visual perception, and functional vision in children with (suspected) cerebral visual impairment.

Background: Brain-based impairments in visual perception (VP), termed cerebral visual impairment (CVI), are heterogeneous.

Aims: To investigate relations between functional vision and (1) visual orienting functions (VOF) and (2) VP.

Methods And Procedures: Forty-four children (Males = 20; Mean age = 9y11m) with (suspected) CVI were tested with an adapted virtual toy box (vTB) paradigm (eye tracking visual search task (VST) and a recognition/memory task), VP tests, a preferential looking eye tracking (PL-ET) paradigm, and the Flemish cerebral visual impairment questionnaire.
