Abstract

PURPOSE: To review visual stimulation (VS) strategies in patients with cerebral visual impairment (CVI) and to design a new VS application (app).

MATERIAL AND METHODS: 394 studies searched with terms “visual stimulation” and “cortical/cerebral visual impairment” were identified, through a search using the PubMed® database from inception to January 9, 2021. From those, 40 were selected. Regarding the development of the VS app, new strategies were applied in a mobile app that is named Steve. The platform was developed in Adobe Phonegap tool, using Javascript, HyperText Markup Language, and Cascading Style Sheets, being compatible with iOS and Android devices and also by other devices using a website. The app allows practicing with innovative animations and geometric shapes with different purposes. The system supports modifiable settings to change the size and velocity of content, to provide personalized learning.

RESULTS: Training with individual objectives, programs and methods of VS have to be adapted for each type of CVI. Stimulation with everyday objects, bright colors and high contrast patterns with smooth movement were the most effective strategies and were inserted into our suggestion of VS app.

CONCLUSION: Our proposal of VS app was created based on previously reported programs to stimulate the children more intensively in a familiar environment. We believe that this project could help the visual rehabilitation process in children, which requires persistence and other behavioral interventions.
