糖尿病视网膜病变患者视网膜中央动脉血流与术后视力改善的关系

Relationship between blood flow of central retinal artery and postoperative visual outcomes in patients with diabetic retinopathy

目的探讨糖尿病视网膜病变玻璃体切除术后患者视力与术前视网膜中央动脉血流之间的关系。方法选取增殖性糖尿病视网膜病变患者53例(53只眼),分析术后视力与术前视力、年龄、视网膜中央动脉管径、血流速度及阻力指数的关系。结果 53例患者术后1个月的视力较术前视力平均提高0.93±0.61,差异有统计学意义(t=7.72,P=0.00)。术后视力仅与术前视力相关(t=2.11,P=0.04),与年龄、视网膜中央动脉管径、血流速度及阻力指数均无关。结论糖尿病视网膜病变玻璃体切除术后视力主要与术前视力相关,与年龄、视网膜中央动脉管径、血流速度及阻力指数均无关。

Objective To explore the relationship between blood flow of central retinal artery and postoperative visual outcomes in patients with diabetic retinopathy.Methods A total of 53 patients with prolife diabetic retinopathy were involved in the study.The postoperative vision was analyzed with age,preoperative vision and radius,blood flow velocity,resistant index(RI)of central retinal artery.Results Compared with preoperative results,the vision of all 53 patients significantly increased 0.93 ±0.61 in average one month postoperatively(t=7.72,P=0.00).The postoperative vision was only related to preoperative vision(t=2.11,P =0.04),not related to age,the radius,flow velocity and RI of central retinal artery.Conclusion The postoperative vision of diabetic retinopathy patients mainly related to its preoperative visual acuity,and not relate to age and radius,velocity,RI of central retinal artery.
