Retinal arteriosclerosis in type 2 diabetes mellitus and its relationship with cardiovascular and cerebrovascular diseases

AIM: To investigate the relationship between retinal arteriosclerosisand cardiovascular and cerebrovascular diseases in type 2 diabetes mellitus. METHODS:Totally 85 patients with type 2 diabetes mellitus in our hospital from January 2016 to January 2017 were selected as the research subjects. Fundus examination was carried out to determine the classification of ophthalmic arteriosclerosis. The blood glucose level of the patients was detected and the glycosylated hemoglobin,fasting blood glucose and postprandial blood glucose levels were measured. All patients were followed up for at least 1 and a half years, and the cardiovascular and cerebrovascular diseases rate was statistically analyzed during the follow up period. The blood glucose level and cardiovascular and cerebrovascular diseases rate in patients with different ocular fundus arteriosclerosis grades were compared, meanwhile the relationship between ocular fundus arteriosclerosis grades with the blood glucose levels and cardiovascular and cerebrovascular diseases rate were analyzed. RESULTS: Among the 85 patients, 15%(13/85), 52%(44/85)and 33%(28/85)of the patients were classified asocular fundus arteriosclerosis grades Ⅰ, Ⅱ and Ⅲ respectively. The cardiovascular and cerebrovascular diseases rate during the follow up period was 27%(23/85). The glycosylated hemoglobin,fasting blood glucose, postprandial blood glucose and cardiovascular and cerebrovascular diseases rates were all increased with the elevation of ophthalmic arteriosclerosis(Prs=0.875, 0.792, 0.835, 0.878; PCONCLUSION:Type 2 diabetes mellitus patients has severe fundus arteriosclerosis, which is closely related to blood glucose level and cardiovascular and cerebrovascular diseases.
