ABSTRACT
Objective To investigate the association between arterial compliance and fundus oculi arteriosclerosis in elderly people. Methods A total of 73 elderly subjects,including 61 elderly patients with fundus oculi arteriosclerosis and 12 healthy volunteers were recruited into the study.Capacitive arterial compliance(C1)and oscillatory arterial compliance(C2)were measured by DO2020 Cardiovascular Profiling Instrument.Moreover,fundus photographs were measured using Canon figure fundus camera. Results There were significant differences in systolic blood pressure(SBP),diastolic blood pressure(DBP),mean artery pressure,pulse pressure,capacitive arterial compliance (C1),and oscillatory arterial compliance(C2)between patients with fundus oculi arteriosclerosis and healthy volunteers(all P<0.05).In multiple regression analysis,the grade of fundus oculi arteriosclerosis was significantly correlated with SBP,DBP,mean artery pressure and pulse pressure (r=0.357,0.261,0.342,0.280,all P<0.05).Moreover,there were significant correlations between the grade of fundus oculi arteriosclerosis and Cl(r=-0.281,P<:0.05),and C2(r=-0.308,P<0.01). Conclusions These findings underscore the efficacy of C1 and C2 in identifying patients with fundus oculi arteriosclerosis.
