Visual Screening with Welch Allyn Spot

Rom J Ophthalmol. 2024 Apr-Jun;68(2):122-127. doi: 10.22336/rjo.2024.23.

Abstract

Objective: Analysis of refractive errors and strabismus deviations following the visual screening of patients with the Welch Allyn Spot device. Material and Methods: This paper is a prospective cross-sectional study of 4281 patients examined with the Welch Allyn Spot device acquired by Lions Club Romania - District 124. The study was conducted between May 2019 and August 2021 and was performed with the help of Lions Club Romania. Results: In the present study, 4281 patients were evaluated and divided into 5 age groups (6-12 months, 12-36 months, 3-6 years, 6-20 years, and 20-100 years). The most frequent age group was 6-20 years, being identified in 51,97% of participants. We found that the most common refractive error was astigmatism, followed by hyperopia and myopia. Thus, (RE) the refractive errors found in the right eye were: astigmatism 93.23%, hyperopia 4.63%, and myopia 1.05%, and in the left eye (LE): astigmatism 90.40%, hyperopia 6.68%, and myopia 0.84%. Of all participants, 8.81% had horizontal strabismus, esotropia being found in the RE in 4.56% of the participants and the LE in 4.74% of them. Conclusions: The pediatric population was the most affected by astigmatism and esotropia. Abbreviations: RE = right eye, LE = left eye, SD = strabismus deviation.

Keywords: autorefractometry; refractive errors; strabismus; visual screening.
