Background

To report the prevalence of refractive error, amblyopia, strabismus, and other ocular pathology in children participating in a vision screening program in American Samoa, a population under-represented in the ophthalmologic literature.

Purpose

To report the prevalence of refractive error, amblyopia, strabismus, and other ocular pathology in children participating in a vision screening program in American Samoa, a population under-represented in the ophthalmologic literature.

Methods

We performed a retrospective chart review of school-based vision screenings using a PlusOptix S12 photoscreener in children 3-18 years of age in American Samoa over a period of 13 months.

n = 743 children

Results

when the eye scan flagged a risk, it was truly there less than half the time

PPV 42 (95% CI 33 to 51)

null 0

33

51

CI excludes the null - significant

More results

The program screened 743 children (mean age, 7.6 ± 2.8 years).

Of these, 122 children failed the vision screening.

Seventy-seven children (63%) met the threshold for spectacle correction.

Conclusion · 1 of 2

In American Samoa, the PlusOptix photoscreener performed similarly to other vision screening programs in the detection of amblyogenic risk factors.

Conclusion · 2 of 2

The participants in this program had a high rate of astigmatism and need for prescription glasses; however, the rate of strabismus and ocular pathology was lower than expected compared to other vision screening programs.

Post

Pediatric eye conditions detected by a school-based photoscreening in American Samoa.

School photoscreening had 42% positive predictive value for amblyopia risk factors.
