目的:探讨灯盏细辛注射液联合视网膜激光光凝术治疗糖尿病视网膜病变的临床效果。 方法:糖尿病视网膜病变患者50例用灯盏细辛注射液联合视网膜激光光凝术治疗，对照组患者50例单纯采用羟苯磺酸胶囊口服，观察治疗前后的眼底改善和视力提高情况及血液流变学的改变。 结果:糖尿病视网膜病变患者用灯盏细辛注射液联合视网膜激光光凝术治疗后，能明显提高糖尿病视网膜病变患者的视力，明显改善患者眼部微循环，总有效率达90％，与对照组相比，差异有统计学意义（P<0.05）。 结论:灯盏细辛注射液联合视网膜激光光凝术治疗糖尿病视网膜病变，具有良好的临床疗效，能更好改善糖尿病视网膜病变的微循环状态，并延缓和改善糖尿病视网膜病变。

AIM:To study clinical effects of Erigeron Breviscapus injection combined with retinal laser photocoagulation in the treatment of diabetic retinopathy. METHODS: Totally 50 cases of diabetic retinopathy were treated with Erigeron Breviscapus injection and retinal laser photocoagulation, control group of 50 cases used simple hydroxybenzene sulfonic acid capsules orally. Fundus, visual acuity and blood rheology changes were observed before and after treatment. RESULTS:Erigeron Breviscapus injection and retinal laser photocoagulation therapy could significantly improve vision in patients with diabetic retinopathy, eye microcirculation in patients was markedly improved.Total effective rate was 90%,the differences were statistically significant (P<0.05). CONCLUSION:Erigeron Breviscapus injection combined with retinal laser photocoagulation in the treatment of diabetic retinopathy has good efficacy, to better improve the microcirculation status of diabetic retinopathy, and delays and improves diabetic retinopathy.
