Summary
The Amblyopia tracker app shows promising feasibility for parents monitoring their child's vision at home during amblyopia treatment. While results are comparable to clinical tests, some variability suggests further app improvements are needed for reliable clinical use.
Area of Science:
- Ophthalmology
- Pediatric Vision Care
- Digital Health Tools
Background:
- Amblyopia, or 'lazy eye', is a common cause of reduced vision in children.
- Effective monitoring during treatment is crucial for successful outcomes.
- Home-based tools can potentially improve treatment adherence and accessibility.
Purpose of the Study:
- To evaluate the feasibility and repeatability of the Amblyopia tracker app for home vision testing by parents.
- To compare home-based test results with in-clinic assessments by orthoptists.
Main Methods:
- Children under 18 with amblyopia used the app for home testing three times over two weeks.
- Parents completed usability questionnaires.
- Home tests were compared to measurements taken by an orthoptist within 48 hours.
Main Results:
- No statistically significant differences were found between repeated home tests or between home and clinical measurements.
- 29% of repeated home tests showed interocular acuity difference (IAD) variability exceeding 0.1 logMAR.
- 97% of parents found the app usable and would recommend its availability.
Conclusions:
- The Amblyopia tracker app demonstrates feasibility and comparable results to clinical assessments for home-based amblyopia monitoring.
- While generally reliable, observed variability in repeated home testing indicates a need for further refinement.
- The app shows potential as a supplementary tool for parents in managing amblyopia treatment.
