OKKO Space Academy to Check Children's Vision at Home

OKKO Space Academy App: Families Checking Their Child's Vision at Home During Amblyopia Treatment

The purpose of this study is to determine the feasibility of the OKKO Space Academy app as a vision measuring and home-monitoring tool for children aged 3-8 years undergoing amblyopia treatment.

There are three objectives to this work:

1. Determine the feasibility of the OKKO Space Academy app for use between clinic visits from the child's and family perspective (i.e., acceptability, usability and engagement).
2. Assess the variability in day-to-day OKKO Health measurements between clinic visits (e.g., do the interim OKKO home vision measurements predict improvements in visual acuity?)
3. Explore agreement between the OKKO Space Academy measures of visual acuity against in-clinic measurements (usual standard of care), including an exploration of intra- and inter-session repeatability.
