Abstract:Objective: To explore the effects of tetramethylpyrazine hydrochloride on visual acuity and vascular endothelial function in patients with non-prolifertive diabetic retinopathy (NPDR). Methods: A total of 142 patients with NPDR admitted to our hospital from October 2016 to October 2018 were selected and divided into two groups according to the simple random grouping. The two groups were given basic treatment, and 71 patients in control group were treated with calcium dobesilate tablets, and 71 patients in observation group were given tetramethylpyrazine hydrochloride tablets on the basis of control group. The treatment efficacy, and visual acuity, intraocular pressure, macular edema and macular thickness, and plasma vascular endothelial growth factor (VEGF), endothelin-1 (ET-1) and endothelium-dependent flow-mediated dilatation (FMD) before and after treatment were compared between the two groups. Results: The total effective rate of treatment in observation group was significantly higher than that in control group (92.96% vs 81.69%) (P<0.05). After treatment, the visual acuity in observation group was significantly better than that in control group (P<0.05), and the macular edema score was significantly lower than that in control group, and the macular thickness was significantly lower than that in control group (P<0.05). The levels of VEGF and ET-1 in observation group were significantly lower than those in control group while the FMD value was significantly higher than that in control group (P<0.05). However, there was no significant change in intraocular pressure between the two groups before and after treatment (P>0.05). Conclusion: Teramethylpyrazine hydrochloride can effectively improve the vision of NPDR patients, reduce macular edema and improve vascular endothelial function.
