| Diabetic retinopathy is one of common complications of diabetics, featured of microangioma, bleeding and exudation of fundus and decrease of eyesight. With high rate of morbidity and blinding, diabetic retinopathy not only brings seriously negative affect to the healthy and life of patients, but also leads heavy load to the patients’families and society. Without knowing the real mechanism, diabetic retinopathy is hard to treat effectively.Recently, some physicians found that even suffered from long term disease, highly myopia type2diabetic patients have lower rate of diabetic retinopathy than those normal sighted ones. It is said that high myopia is negatively related to diabetic retinopathy.Objective:To investigate the correlation between high myopia retinopathy and diabetic retinopathy.Methods:We studied402cases of diabetic retinopathy,201with high myopia and201without myopia. All patients were treated in Wangjing Hospital of China Academy of Chinese Medical Sciences, Guang’anmen Hospital of China Academy of Chinese Medical Sciences, Peking University People’s Hospital and Teaching Hospital of Chengdu University of Traditional Chinses Medicine diabetic department and ophthalmologic department in last10years. This subject adopts retrospective cohort study. The medical records data of fundus change, eyesight, diopter, retinal detachment and diabetes conditions were observed contrastively. All data were analyzed statistically by SPSS software.Results:①The clinical stage of diabetic retinopathy between high myopia group and emmetropia group had a statistically significant difference(P<0.01).②In high myopia group, the course of type2diabetes mellitus between each clinical stage of diabetic retinopathy had no significant difference (P>0.05).In emmetropia group, the course of type2diabetes mellitus between each clinical stage of diabetic retinopathy had no significant difference (P>0.05).In the same clinical stage of diabetic retinopathy, the course of type2diabetes mellitus between high myopia group and emmetropia group had no significant difference (P>0.05).In proliferative diabetic retinopathy, the course of type2diabetes mellitus between high myopia group and emmetropia group had no significant difference (P>0.05).③The retinal detachment between high myopia group and emmetropia group had no significant difference (P>0.05).Conclusion:①High myopia retinopathy has effect on the severity of diabetic retinopathy,②High myopia retinopathy has no effect on the rate of diabetic retinopathy progression,③High myopia retinopathy has no effect on the retinal detachment. |
