Three out of every 100 children in the United States suffer from amblyopia, a condition where the brain fails to develop normal vision in one or both eyes. If left untreated, this leads to permanent monocular vision loss that cannot be corrected by glasses or contact lenses in adulthood.
Bridging the Specialist Gap
Recent workforce studies reveal a massive geographic imbalance in the distribution of pediatric optometrists and ophthalmologists across the U.S., with specialists clustering in specific states while leaving others with zero access. To counter this, the Pediatric Eye Disease Investigator Group (PEDIG) has launched the Amblyopia Navigator Decision-Support Instrument (ANDI).
Developed by an NIH-funded research network of over 400 investigators, ANDI functions as an open-access clinical decision-support tool. It is designed to guide general eye care clinicians—who may lack specialized pediatric training—through the diagnosis and management of amblyopia. The instrument draws on evidence from 147 published studies to provide individualized treatment advice.
From Diagnosis to Digital Treatment
Once a clinician identifies amblyopia, ANDI assists in determining the optimal glasses prescription and monitoring periods. For the roughly one-third of children who do not respond to glasses alone, the tool walks the provider through secondary interventions. These include patching the stronger eye, using atropine eye drops to temporarily blur vision, or implementing newer digital treatments delivered via specialized games and videos.
If a patient stops progressing, the tool provides specific logic for whether to increase treatment intensity, switch approaches, or refer the case to a specialist. This systematic approach aims to minimize the gaps in access to pediatric ophthalmic care by empowering local providers with high-level expertise.
By distilling complex clinical literature into actionable steps, ANDI enables more consistent outcomes for children regardless of their proximity to a major pediatric eye center.
