Interventions

All participants will receive training that will consist of playing the computer game for approximately 20-30 minutes to complete one session, and completing five sessions per week for 6 weeks (30 tra

Eligibility

Sex/Gender

All

Inclusion criteria

Inclusion criteria: Current inclusion criteria as of 18/07/2018: Young people (7-25 years old, male and female) with bilateral visual field loss caused by a lesion of the post-geniculate optic pathway or visual cortex Previous inclusion criteria: Young people (8-25 years old, male and female) with bilateral visual field loss caused by a lesion of the post-geniculate optic pathway or visual cortex

Exclusion criteria

Exclusion criteria: 1. Cognitive or physical impairments which cause a formal assessment of the visual field (standard automated perimetry) to be impractical 2. The inability to use either a mouse, keyboard or touch screen to access the game

Design outcomes

Primary

Measure	Time frame
The speed at which participants perform 'activities of daily living' (ADLs), measured one month before the rehabilitation programme begins, immediately before and immediately after the rehabilitation, and one month after the rehabilitation ends.	—

Secondary

Measure	Time frame
Current secondary outcome measures as of 18/07/2018: 1. Scores on two patient-reported outcome questionnaires: 1.1. The Impact of Vision Impairment for Children (IVI_C) and 1.2. The Cardiff Visual Ability Questionnaire for Children (CVAQC) Measured one month before the rehabilitation programme begins, immediately before and immediately after the rehabilitation, and one month after the rehabilitation ends. Previous secondary outcome measures: 1. Perimeter and size of the visual field border 2. Scores on two patient-reported outcome questionnaires: 2.1. The Impact of Vision Impairment for Children (IVI_C) and 2.2. The Cardiff Visual Ability Questionnaire for Children (CVAQC) 3. Speed at which participants perform a mobility course and the percentage of brightly coloured cards found that are placed along the route. Measured one month before the rehabilitation programme begins, immediately before and immediately after the rehabilitation, and one month after the rehabilitation ends.	—
