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 during early childhood, this vision loss becomes permanent and cannot be corrected by glasses or contact lenses in adulthood.
Bridging the specialist gap with ANDI
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 coverage. To address 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 doctors—who may lack specialized pediatric training—through the entire diagnostic and management lifecycle of amblyopia. The instrument draws on evidence from 147 published studies to provide individualized treatment advice.
From prescription optimization to digital therapeutics
Managing amblyopia requires precise, iterative adjustments. ANDI assists clinicians in determining the optimal glasses prescription based on specific clinical findings and helps decide how long to monitor whether glasses alone can improve vision—a strategy that works for up to one-third of children.
When glasses are insufficient, the tool walks the clinician through a hierarchy of escalating interventions. This includes patching the stronger eye, using atropine eye drops to temporarily blur vision in the stronger eye, or implementing newer digital treatments delivered via specially designed games and videos. If a patient stops progressing, the tool provides specific logic for whether to increase treatment intensity, switch approaches, or refer the patient to a specialist.
By distilling complex ophthalmic literature into actionable steps, ANDI enables more consistent care in regions currently underserved by pediatric specialists. This deployment of evidence-based decision support marks a significant step in reducing the long-term societal burden of preventable monocular vision loss.
