Insights

Early detection of visual impairment in young children is challenging. A new smartphone system, Apollo Infant Sight (AIS), analyzes gazing and facial features to identify over 16 ophthalmic disorders, improving screening accessibility.

Area of Science:

  • Ophthalmology
  • Pediatrics
  • Mobile Health (mHealth)

Background:

  • Early detection of visual impairment in young children is critical but hindered by limited cooperation with standard tests.
  • Traditional screening methods struggle with real-world application, despite observable features in visually impaired children.
  • Existing challenges necessitate innovative, accessible screening tools for early identification of pediatric visual disorders.

Purpose of the Study:

  • To develop and validate a mobile health (mHealth) system for early detection of visual impairment in infants and young children.
  • To assess the efficacy of the smartphone-based Apollo Infant Sight (AIS) system in identifying children with ophthalmic disorders.
  • To evaluate the system's performance in both clinical settings and at-home use by untrained caregivers.

Main Methods:

  • Development and validation of the Apollo Infant Sight (AIS) system using videos from 3,652 children (≤48 months).
  • AIS records and analyzes gazing behaviors and facial features under visual stimuli to detect visual impairment.
  • Prospective data collection for internal and external validation, including at-home implementation tests.

Main Results:

  • AIS achieved an area under the receiver operating curve (AUC) of 0.940 in internal validation and 0.843 in external validation.
  • The system demonstrated strong performance in at-home use by untrained parents/caregivers, achieving an AUC of 0.859.
  • AIS successfully identified children with a wide range of 16 ophthalmic disorders, adapting to diverse testing conditions.

Conclusions:

  • The smartphone-based Apollo Infant Sight (AIS) system offers a promising mHealth solution for early detection of visual impairment in young children.
  • AIS has the potential to significantly improve screening accessibility and accuracy for pediatric ophthalmic disorders.
  • The system empowers healthcare professionals, parents, and caregivers with a tool for identifying visual impairment across various settings.
