Abstract:
AIM:To observe the clinical efficacy of modified Buyang Huanwu Decoction in treating non-proliferative diabetic retinopathy(NPDR)of qi and yin deficiency and stagnation of collaterals, and to quantitatively analyze the changes in peripapillary vessel density before and after treatment using optical coherence tomography angiography(OCTA).METHODS:A randomized controlled trial was used to collect a total of 58 patients(99 eyes)with qi and yin deficiency and stagnation of collaterals NPDR who visited our hospital from June 2022 to November 2022, and patients were randomly divided into an observation group(n=29, 51 eyes)and a control group(n=29, 48 eyes). The control group received basic treatment according to the recommendations for DR published by the American Academy of Ophthalmology in 2019(blood glucose control, diabetes health education, and regular follow-up for patients with mild NPDR; and add local/grid-like laser photocoagulation if necessary for patients with moderate NPDR), while the observation group received modified Buyang Huanwu Decoction in addition to the basic treatment for 1mo. The best-corrected visual acuity(BCVA), traditional Chinese medicine(TCM)efficacy, peripapillary telangiectasia vessel density(ppVD), and changes in peripapillary retinal nerve fiber layer(pRNFL)thickness were compared between the two groups before and after treatment.RESULTS:The BCVA(LogMAR)of the observation group was 0.20(0.10, 0.30)after 1mo of treatment, which was significantly improved compared with that of the control group of 0.30(0.20, 0.40; P<0.05). The TCM efficacy in the observation group after 1mo of treatment was better than that in the control group(P<0.05). The ppVD in all quadrants of the observation group showed a significant improvement at 1mo after treatment, and the ppVD in all quadrants of the observation group was higher than that of the control group(P<0.05). The pRNFL thickness in the superior, temporal, and average peripapillary areas of the observation group increased after 1mo of treatment, and the pRNFL thickness in the superior, temporal, inferior quadrants, and average peripapillary area of the observation group was higher than that of the control group(P<0.05).CONCLUSION:Modified Buyang Huanwu Decoction can improve visual acuity and enhance TCM efficacy in patients with NPDR of qi and yin deficiency and stagnation of collaterals. It may be related to its ability to improve ppVD and reduce damage to the pRNFL.
