Abstract:
Objective To explore the value of ocular fundus artery hemodynamics in diabetes by the correlation study between ocular fundus artery and glycosylated hemoglobin(GHb).Methods GHb was checked in 98 patients (196 eyes) in diabetes,including 49 cases (98 eyes) before treatment and 49 cases (98 eyes) after treatment,and normal group of 100 cases (200 eyes)An all cases,color Doppler ultrasonography was used for monitorind ophthalmic artery(OA),central retinal artery(CRA) and posterior ciliary artery (PCA).Finally,the differences of the parameters vauels of the the OA,CRA,and PCA between diabetic and normal group were studied in order to find out the relationship with GHb.Results Of 98 patients in diabetes,peak systolic velocity and end diastolic velocity of fundus artery decreased,resistance index increased(RI).There was significant difference between diabetic and normal group(P ＜0.05),and a significant difference was exited between diabetic group before and after treatment(P ＜0.05).GHb were negatively correlated with the velocity of fundus artery,and positively correlated with RI.Conclusions Evaluation of ocular fundus artery hemodynamics in diabetes can provide useful information for diabetic retinal perfusion and function change.For evaluation of diabetic retinal disease,it is of great value in clinical application.
