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 کاملcorrelation of hand dominancy and eye dominancy with visual acuity and refractive errors
purpose: to determine the correlation between hand dominancy and eye dominancy with visual acuity and refraction in subjects with refractive errors. methods: this cross-sectional study includes 620 patients undergoing lasik. their refractive error (dry and cycloplegic), hand dominancy, eye dominancy (by hole-in-the-hand method) and visual acuity were determined. exclusion criteria were monocula...
متن کاملCase finding for refractive errors: assessment of refractive error and visual impairment in children.
The World Health Organization informal planning meeting, in July 2000, clearly indicated that detailed comparisons of refractive error prevalence across study reports are generally not possible because of different measurement methods and definitions. Further, because most studies are carried out using samples of unknown representativeness, interpretation of the findings in a population-based c...

متن کاملVisual Acuity Before and After Occlusion Therapy in Children and Adolescents (Aged 5-13 years) Amblyopia
Purpose: To evaluate the effect of occlusion therapy on visual acuity in children and adolescents (aged 5-13 years) with amblyopia. Methods: This experimental study followed a pretest-posttest design. Totally, 72 people with amblyopic eyes (visual acuity between 20/100 and 20/25) were selected through convenient sampling. The visual acuity was assessed at 1, 3, and 6 months after starting occlu...
