An Analysis of Visual Outcomes in the Community-Based Vision Screening Programs

Abstract

Introduction: A community vision screening is a quick eye examination that searches for potential vision problems. Screening helps to detect visual disorders early. This study intended to determine the outcomes of the vision screening. The association between demographic variables, vision testing, and vision screening outcomes was also investigated. Methods: Vision screening data conducted from 2017 to 2020 were obtained. Demographic data (age, gender, and location) and optometric findings (distance visual acuity (DVA), near visual acuity (NVA), refractive errors, intraocular pressure (IOP), and retina abnormalities) were extracted and analyzed. The pass or fail vision screening and causes were determined. Results: Thirty-five percent (35%) were failed the vision screening. The elderly was the most likely to fail (17%). The females and males showed an equal proportion of failure rate. Those who failed screening in urban areas (27%) were greater than in rural areas (8%). Reduced DVA was the most common reason for failed vision screening, followed by reduced NVA. Age (p<0.001) and location (p<0.001) was significantly linked with the outcome of vision screening. DVA (p<0.001), NVA (p<0.001), IOP measurement (p=0.006) and ophthalmoscopy findings (p<0.001) demonstrated significant association with vision screening results. Conclusion: The failure rate in community vision screening was high. Age, location, DVA, NVA, IOP measurement, and fundus evaluation were associated with vision screening outcomes. Outreach initiatives help identify potential vision problems in the community. This evidence is vital for determining the need for treatment and management of optometry services and planning for targeted vision screening programs, thereby preventing vision loss.
