validity of uncorrected visual acuity measured in vision screening programs for detecting refractive errors
purpose: uncorrected visual acuity is the only variable measured in vision screening programs in many countries worldwide. the aim of this study was to calculate the sensitivity, specificity, and predictive value of the uncorrected visual acuity in the screening programs for the diagnosis of refractive errors. methods: in this cross-sectional study, of 4,157 students in the first year of primar...
متن کاملChart for visual acuity screening.
SIR, -I read with great interest the paper by Wong and Kaye on a suggested chart for visual acuity screening.' However, I was surprised to find that they recommended widespread clinical use of this chart without any clinical data to confirm its suitability. The statistical argument they use is compelling, but surely a comparison with other methods of acuity testing should be undertaken to confi...
متن کاملLearner-to-learner visual acuity screening: a solution for early identification of visual acuity disabilities.
BACKGROUND The National School Health Policy guidelines (2002) stipulate that primary school learners should have their vision, speech, hearing, mental health, teeth, nutrition and development screened annually. In reality, especially in under-resourced areas such as the Eastern Cape, many learners with disabilities are not identified, with profound consequences for their ability to learn. ME...

متن کاملScreening for Significant Refractive Error Using a Combination of Distance Visual Acuity and Near Visual Acuity
PURPOSE To explore the effectiveness of using a series of tests combining near visual acuity (NVA) and distance visual acuity (DVA) for large-scale screenings for significant refractive error (SRE) in primary school children. METHOD Each participant underwent DVA, NVA and cycloplegic autorefraction measurements. SREs, including high myopia, high hyperopia and high astigmatism were analyzed. C...
