Global magnitude of visual impairment caused by uncorrected refractive errors in 2004.
Estimates of the prevalence of visual impairment caused by uncorrected refractive errors in 2004 have been determined at regional and global levels for people aged 5 years and over from recent published and unpublished surveys. The estimates were based on the prevalence of visual acuity of less than 6/18 in the better eye with the currently available refractive correction that could be improved...
متن کاملValidity 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 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...
متن کاملInvestigation of visual acuity and residual refractive error after cataract surgery in patients with senile cataract by phacoemulsification
Background and Aim: Vision improvement and reduction of refractive errors are considered as important goals of cataract surgery. The purpose of this study was to evaluate residual refractive errors after cataract surgery in the patients with senile cataract in Shahid Rahimi Hospital in Khorramabad City between 2017 and 2018. Material and Methods: This cross-sectional study included 178 patients...
