Title: A Study on the Relationship Between Diabetic Retinopathy and Blood Stasis Syndrome
Abstract: Objective:To investigate the characteristics of blood stasis syndrome and its role on the pathogenesis of diabetic retinopathy (DR) by studying the relationship between DR and blood stasis syndrome. Methods:185 patients (283 eyes) with diabetes mellitus (DM) were subjected to DR group and non-DR group.Three types of TCM syndrome were observed, i.e.,Qi and Yin deficiency (QYD), Yin and Yang deficiency (YYD) and blood stasis and Qi stagnation (BSQS). The fundi of DR were divided into simple pre-proliferative and proliferative stages. The fundus fluorescein angiography(FFA) and blood rheology were also analyzed. Results:(1) The arm-to-retina circulation time(t A-RC ) of DM Patients was significantly different from that of normal control group (P 0.001 ).(2)Blood viscosity, hematocrit and plasma viscosity of DR patients were significantly different from that of normal control group (P 0.05 ). These differences were more prominent in the cases of BSQS syndrome which was seen in most cases of DR in proliferative stage. Conclusions: The changes of FFA and blood rheology are the most important characteristics in the whole course of DR. Elimination of blood stasis is the key of treatment, and the TCM syndrome differentiation should be combined with the fundus examination.
