糖尿病眼底病变主要是因为血糖长期增高对视网膜血管产生的影响,它是糖尿病的一个特异性并发症,即由高血糖引起的器官损害,这与糖尿病大血管病变(如心血管疾病)不太一样,心血管疾病除了与高血糖有关,还和高血压、血脂异常等密切相关。糖尿病患者如果血糖控制不好,相当一部分人会发生视网膜病变,一部分人还会进展到增殖期视网膜病变,影响视力甚至导致失明,严重影响患者生活质量。 Diabetic retinopathy is mainly due to the long-term effects of elevated blood glucose on the retinal vasculature, which is a specific complication of diabetes mellitus, organ damage caused by hyperglycemia, which is not the same as diabetic macroangiopathy (such as cardiovascular disease) In addition to cardiovascular disease and hyperglycemia, but also with high blood pressure, dyslipidemia are closely related. If the blood glucose control in patients with diabetes is not good, a considerable number of people will develop retinopathy, some people will progress to proliferative retinopathy, affecting vision and even lead to blindness, seriously affecting the quality of life of patients.
