Three in every 100 U.S. children suffer amblyopia, yet only a fraction reach a pediatric ophthalmologist.
How ANDI Works
ANDI, the Amblyopia Navigator Decision‑Support Instrument, is a browser‑based wizard that starts with a simple eye‑exam input. It then calculates the optimal glasses prescription, decides whether glasses alone can suffice, and if not, walks the clinician through patching schedules, atropine dosing, or newer game‑based therapies. When a child stalls, the tool suggests intensifying treatment, re‑evaluating the prescription, or referring to a specialist. Follow‑up visits and recurrence alerts are built in, so the entire care pathway stays on track.
Evidence Base and Reach
The algorithm draws on 147 peer‑reviewed studies and is the product of PEDIG, an NIH‑funded network of over 400 investigators. By publishing the tool at https://public.jaeb.org/pedig, the team has made it free and open‑access, allowing clinicians in rural or underserved areas to tap the same evidence that a pediatric ophthalmologist would use. The design also accommodates offline use: clinicians can print the embedded figures as quick reference sheets.
Implications for the Care Gap
Geographic studies show pediatric optometrists and ophthalmologists cluster in a handful of states, leaving many children without local expertise. ANDI mitigates this by democratizing decision‑making. A non‑specialist eye doctor can now prescribe patching for a third of children who improve with glasses alone, or advance to atropine or digital therapy when needed. The tool’s step‑by‑step guidance reduces variability in care and ensures that treatment intensity escalates only when evidence warrants.
With ANDI, clinicians in underserved regions can now prescribe evidence‑based patching or digital therapy with the confidence of a specialist, potentially halving the untreated amblyopia burden.
