目的：探讨变性性近视(degenerative myopia)与糖尿病视网膜病变(diabetic retinopathy，DR)的相关性。
方法：2型糖尿病患者106例，按是否合并变性性近视分为变性性近视组(48例)和非近视组(58例)，均行眼底检查及眼底血管荧光造影(fluorescence fundus angiography，FFA)，明确DR分期，对两组DR患病率及分期进行比较分析。
结果：变性性近视组DR患病率70.8%，仅有Ⅰ期或Ⅱ期表现，无增殖期改变； 非近视组患者DR患病率93.1%，Ⅰ～Ⅴ期病变均有发生。
结论：变性性近视可以阻止DR的发生，可能是DR的保护性因素。

[Abstract]
AIM: To investigate the correlation between degenerative myopia and diabetic retinopathy(DR).
METHODS: Totally 106 cases with diabetes B were divided into the degenerative myopia group(48 cases)and the no degenerative myopia group(58 cases). Fundus examination and fluorescence fundus angiography(FFA)were performed on all cases. The occurrence and stage of DR were compared between the 2 groups.
RESULTS: The occurrence of DR of the no degenerative myopia group(93.1%)was much higher than that of the degenerative myopia group(70.8%). Only retinopathy of stageⅠor Ⅱ was observed in the degenerative myopia group without lesion in proliferating phase, while retinopathy of stageⅠto Ⅴ could be found in the no degenerative myopia group.
CONCLUSION: Degenerative myopia can prevent DR from occurrence and may be a protective factor for DR.
