Amblyopia Elimination Project: Pediatric Medical Home-Based Community Vision Screening
Insights
Providing pediatric medical homes with vision screening equipment significantly increased high-quality screenings for preschoolers. This initiative aims to reduce preventable vision loss in children through accessible screening tools.
Area of Science:
- Public health initiatives
- Pediatric ophthalmology
- Vision screening technology
Background:
- Early detection of vision impairments in preschoolers is crucial for preventing long-term vision loss.
- Access to specialized screening equipment in pediatric settings can be a barrier to comprehensive eye care.
- The Naples Lions Amblyopia Elimination Project aimed to address this gap.
Purpose of the Study:
- To determine if improved access to instrument-based screening equipment increases the number of high-quality, age-appropriate vision screenings for preschool-aged children.
- To evaluate the effectiveness of a community-based program in enhancing vision screening provision.
Main Methods:
- The Naples Lions Amblyopia Elimination Project distributed SPOT Vision Screeners to pediatric medical homes.
- Participating clinics provided data on screening numbers, referrals, and outcomes.
- The study tracked the adoption of screening equipment in pediatric practices over time.
Main Results:
- Instrument-based vision screening equipment use in pediatric medical homes increased from 4 in 2012 to 19 by 2017.
- The percentage of pediatric medical homes utilizing SPOT Vision Screeners rose to 76% in 2017.
- In 2017, 6,052 preschool children received screenings through this program.
Conclusions:
- Facilitating access to vision screening equipment demonstrably increased the provision of essential eye care services for young children.
- This philanthropic model represents an innovative approach to eliminating preventable vision loss in the pediatric population.
- The project highlights the success of community-based efforts in improving child vision health outcomes.
Purpose:
To examine whether facilitating access to instrument-based screening equipment will increase the total number of high-quality, age-appropriate vision screenings provided to the preschool aged population.
Methods:
The goal of the Naples Lions Amblyopia Elimination Project was to place a SPOT Vision Screener (Welch Allyn, Skaneateles Falls, NY) in every pediatric medical home using philanthropic dollars. Participating medical homes agreed to provide data on the number of children screened, number of referrals made, criteria for referral, and follow-up notes regarding examination outcomes.
Results:
In 2012, only 4 of the 23 pediatric medical homes in Collier County were using instrument-based vision screening equipment. By 2017, 19 of the 25 pediatric medical homes (76%) used SPOT Vision Screeners. In 2017, 6,052 preschool children were screened in these 19 pediatric medial homes.
Conclusions:
The concept for this community-based philanthropic effort is original in its design and implementation and is a significant step forward in the goal to eliminate preventable permanent vision loss in children. [J Pediatr Ophthalmol Strabismus. 2019;56(3):146-150.].
