Refractive errors in an urban population in Southern India: the Andhra Pradesh Eye Disease Study.

摘要: PURPOSE, To assess the prevalence, distribution, and demographic associations of refractive error in an urban population southern India. METHODS. Two thousand five hundred twenty-two subjects all ages, representative Hyderabad population, were examined population-based Andhra Pradesh Eye Disease Study. Objective subjective refraction was attempted on >15 years age with presenting distance and/or near visual acuity worse than 20/20 either eye. Refraction under cycloplegia ≤ 15 age. Spherical equivalent >0.50 D eye considered as error. Data objective analyzed for RESULTS. available 2,321 (92.0%) subjects. In age, age-gender-adjusted prevalence myopia 4.44% (95% confidence interval [CI], 2.14%-6.75%), which higher those 10 to (odds ratio, 2.75; 95% CI, 1.25-6.02), hyperopia 59.37% Cl, 44.65%-74.09%), astigmatism 6.93% 4.90%-8.97%). 19.39% 16.54%-22.24%), 9.83% 6.21%-13.45%), 12.94% 10.80%-15.07%). With multivariate analysis, significantly Lens Opacity Classification System III nuclear cataract grade ≥3.5 9.10; 5.15-16.09), education class 11 or 1.80; 1.18-2.74); ≥30 compared 16 29 37.26; 11.84-117.19), females 1.86; 1.33-2.61), belonging middle upper socioeconomic strata 2.10; 1.09-4.03); ≥40 3.00; 2.23-4.03) college level 1.73; 1.07-2.81). CONCLUSIONS. These data distribution could enable planning eye-care services reduce impairment caused by If these are extrapolated 255 million India, among estimated 30 people would have myopia, 15.2 hyperopia, 4.1 not concurrent hyperopia; addition, based cycloplegia, 4.4 children 2.5 hyperopia.
