Epidemiology of uncorrected refractive errors in type 2 diabetics aged 50 and above in Funing County, China: the Jiangsu Diabetic Eye Study

This study aimed to determine the prevalence of uncorrected refractive errors (URE) among individuals aged 50 and above in Funing county, Jiangsu province. Using cluster sampling, 1,910 participants were analyzed, revealing a URE prevalence of 25.63%. The study further categorized URE into myopia, hyperopia, astigmatism, myopia with astigmatism, and hyperopia with astigmatism. Older age, higher glycosylated hemoglobin levels, myopia, and lens status were identified as independent factors influencing URE. Participants aged 70-80 years and those above 80 years had higher odds of URE compared to those under 60 years. Similarly, individuals with glycosylated hemoglobin levels of 7.1-8.0% and over 10% had increased odds of URE. Myopia, especially moderate and high myopia, significantly increased the risk of URE, as did the presence of eye lens opacity. The study concludes that URE is a significant contributor to visual impairment in diabetic patients aged 50 and above in Funing county, Jiangsu province. Health departments should focus on promoting eye health among diabetic patients, including regular optometry and fundus examinations.
