About this study
Official title: VIPPSTAR-G2 Clinical Study: The Superiority of a Co-design in the Development of a Serious Game for Children With Cerebral Visual Impairment
The goal of this clinical trial is to evaluate the superiority of the through codesign redesigned game joyVision over the iVision game for children with a cognitive age between 3 and 12 with CVI.
The main question it aims to answer is:
- Does the joyVision game have a better adherence than the iVision game
Participants will play with both Ivision and joyVision for one month, in a randomized AB/BA sequence.
- Conditions
- Cerebral Visual Impairment
- Being tested
- serious game
- Medical subject headings
- Blindness, Cortical

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
play frequency (time frame: immediately after the intervention). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Oct 2026.
