目的对糖尿病视网膜病变与高度近视相关性进行探讨。方法选取22例2型糖尿病患者作为研究对象,眼科检查一眼屈光度≥-6 D,另眼为正视眼,行眼镜眼底检查和眼底彩色照相,以及光相干断层扫描(OCT)、荧光素眼底血管造影(FFA)检查。结果分布于全阶段的是正视眼组糖尿病视网膜病变,发生率明显降低的是高度近视眼组糖尿病视网膜病变,特别是在病程的增殖期中未见改变。高度近视眼和对侧正视眼黄斑囊样水肿发生率之间比较,差异有统计学意义(χ2=15.65,P<0.05)。结论患者既往高度近视与其患糖尿病导致双眼视网膜病变的严重程度不对称有明显相关性,糖尿病患者既往高度近视对其视网膜病变的保护作用非常明显,且近视度数与其保护程度正相关。
Objective To investigate the correlation between diabetic retinopathy and high myopia. Methods Twenty-two patients with type 2 diabetes mellitus (T2DM) were enrolled in this study. One eye was examined with diopter≥-6 D, the other with eyelid eye examination, fundus examination and fundus color photography, as well as optical coherence tomography (OCT), fluorescein angiography (FFA) examination. The results distributed in all stages of the eyelid eye diabetic retinopathy, the incidence was significantly lower in the high myopia group diabetic retinopathy, especially in the duration of the proliferative phase was not changed. There was significant difference between the incidence of macular cystoid edema in high myopia and contralateral eyes (χ2 = 15.65, P <0.05). Conclusions There is a significant correlation between the degree of myopia and the degree of asymmetry of binocular retinopathy in patients with previous high myopia. The high degree of myopia in diabetic patients has a very significant protective effect on the retinopathy, and the degree of myopia is positively correlated with the degree of protection.
