Abstract: Objective To investigate the status of visual impairment in patients with type 2 diabetes mellitus （T2DM） in Enshi City and analyze its related factors, to provide a reference for the prevention of visual impairment in patients with T2DM. Methods The patients with T2DM in Enshi from January 2019 to December 2021 were selected as the research objects. The descriptive epidemiological analysis method was used to analyze the status of visual impairment in patients with T2DM. The personal related data of the patients with T2DM were obtained, and the influencing factors of visual impairment were analyzed by univariate and multivariate Logistic regression analysis. Results A total of 2 986 patients with T2DM were included in the effective study, and 679 cases of visual impairment were detected, with a detection rate of 22.74%. There were 265 cases of monocular visual impairment and 414 cases of binocular visual impairment. Among them, 187 cases were ametropia, 93 cases were cataracts, 308 cases were retinopathy, and 91 cases were other. Multivariate Logistic regression analysis showed that the older the patients with T2DM were （OR=1.439）, the longer the course of disease （OR=2.143）, unfulfilled blood glucose control （OR=2.366）, poor drug compliance （OR=2.956）, the worse their diet health （OR=1.937）, unfulfilled physical exercise （OR=1.783）, anxiety （OR=1.318）, and depression （OR=1.990） in Enshi, the higher the possibility of visual impairment. Conclusions The visual impairment of patients with T2DM in Enshi is more common in terms of binocular impairment, retinopathy, and ametropia, which are affected by many factors. We should pay attention to the relevant population and effectively intervene against such changeable factors as blood glucose control, drug compliance, diet health, physical exercise, and psychological health, to help patients with T2DM control blood glucose, and prevent and reduce visual impairment.
