| 摘要: |
| 目的：研究行玻璃体切除的糖尿病视网膜病变患者的术后视力与视网膜中央动脉血流之间的关系。
方法：回顾性非随机临床病例研究，共收集增殖性糖尿病视网膜病变患者53例53只眼纳入研究，分析手术后患者的视力与术前视力、视网膜中央动脉管径、血流速度、阻力指数、年龄、性别之间的关系。
结果：患者术后一个月的视力与术前视力相比，平均提高1.125±0.90，差异有统计学意义。经过多重线性回归分析及散点图分析，术后视力仅与术前视力相关，与视网膜中央动脉血流之间无明确相关关系。
结论：行玻璃体切除的糖尿病视网膜病变患者的术后视力主要与其术前视力相关，而与视网膜中央动脉血流之间没有明确的相关关系。 |

| Abstract: |
| Objective To study the relationship between blood flow of central retinal artery and visual outcomes in diabetic patients with vitrectomy. Methods This is a retrospective nonrandomized clinical case study. A total collection of 53 eyes of 53 patients（from May 2014 to October 2016） with prolife diabetic retinopathy (PDR) had been involved in the study. The relationship between blood flow of central retinal artery and visual outcomes were observed. Results All patients have increased best corrected visual acuity by 1.125 +/- 0.90 in one month postoperation averagely. Through multiple linear regression analysis and scatter diagram analysis, postoperative vision is only related to preoperative visual acuity, with no clear relationship between the central retinal artery blood flow and postoperative vision. Conclusion The postoperative vision of diabetic retinopathy patients mainly related to its preoperative visual acuity, and there is no clear relationship between the central retinal artery blood flow and the postoperative vision . |
