Summary
Parents can reliably screen preschool children's vision using the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) Vision Screening App. This app is a promising and user-friendly tool for vision screening in Malaysian preschoolers.
Area of Science:
- Ophthalmology
- Pediatrics
- Health Technology
Background:
- Early detection of vision impairments in preschool children is crucial for development.
- Traditional vision screening methods can be resource-intensive and may face challenges in accessibility.
- Mobile health applications offer potential solutions for improving vision screening accessibility and efficiency.
Purpose of the Study:
- To evaluate parental performance using the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) Vision Screening App for preschool children.
- To assess the reliability and accuracy of the AAPOS Vision Screening App as a vision screening tool.
Main Methods:
- 195 Malaysian preschoolers (5-6 years old) participated in the study.
- Parents and a screening doctor used the AAPOS app (Lea symbols) for visual acuity testing.
- Results were compared to each other and to a gold standard optometrist assessment.
Main Results:
- Parents demonstrated good agreement with optometrists (intraclass correlation coefficient P < 0.001).
- The app achieved high sensitivity and specificity in detecting visual acuity issues.
- 91.3% of parents found the app acceptable and easy to use, with screening taking approximately 3 minutes.
Conclusions:
- The AAPOS Vision Screening App is a reliable and promising tool for vision screening in Malaysian preschool children.
- Parental use of the app demonstrates good performance and high acceptability.
- This technology can enhance early detection of vision problems in young children.
