Amblyopia

Affects 1-3% of the population

Is the most common cause of unilateral blindness in adults1

Amblyopia is treatable

Glasses

Patching

Research Focus on Access to Care

Phone Follow up After Vision Screening

Geoinformatics for driving distances to care

Geoinformatics for targeting at risk children

Conclusions:

Astigmatism readings prompting referral with the SPOT

photoscreener are stable between annual screenings.

Compliance with follow up should be emphasized in children

with cylindrical error who fail repeat vision screening

Improving follow up after vision

working with geo-data for better understanding and interpretation of human

interaction” –IGI Global

A Dream for the Future

Parents Understand Amblyopia like Bike Helmets!

Conclusions

Community-based photoscreening is an efficient way to reach children

Educating parents regarding the importance of follow up may require several

phone calls

Most of the communities in our area have providers close to screening sites.

Follow-up with providers in the local community helps at-risk children to

develop a relationship with a provider near their home

Geoinformatics is a tool that can help screening programs to reach the most

vulnerable children efficiently
