目的：探讨糖尿病视网膜病变(DR)继发毛细血管异常扩张的影响因素。 方法：前瞻性研究。选取2021-01/2023-01于我院就诊的DR患者153例240眼，分析DR继发毛细血管异常扩张的影响因素。结果：根据是否继发毛细血管异常扩张将纳入患者分为扩张组(40例77眼)和非扩张组(113例163眼)，两组患者合并糖尿病性黄斑水肿情况、硬性渗出分级及空腹血糖水平具有显著差异(P<0.05)。Logistic回归分析结果显示，合并糖尿病性黄斑水肿、硬性渗出分级较高、高血糖水平是DR继发毛细血管异常扩张的危险因素(P<0.05)。结论：DR继发毛细血管异常扩张的发生可能与合并糖尿病性黄斑水肿、3级硬性渗出及高血糖水平有关。

AIM:To investigate the influencing factors of abnormal telangiectasia secondary to diabetic retinopathy(DR).METHODS: Prospective studies. A total of 153 cases(240 eyes)with DR treated in our hospital from January 2021 to January 2023 were selected to analyze the risk factors of abnormal telangiectasia secondary to DR and its predictive efficacy.RESULTS: The patients were divided into dilated group(77 eyes of 40 cases)and non-dilated group(163 eyes of 113 cases)according to whether they had secondary abnormal telangiectasia. There were significant differences in diabetic macular edema, hard exudates grade and fasting blood glucose level between the two groups(P<0.05). Logistic regression analysis showed that diabetic macular edema, high hard exudates grade and high blood glucose level were the risk factors for abnormal telangiectasia secondary to DR(P<0.05).CONCLUSION: The occurrence of telangiectasia secondary to DR may be related to diabetic macular edema, grade 3 hard exudates and high blood glucose level.
