Abstract

Abstract: Objective To investigate the relationship between BRVO (branch retinal vein occlusion) and internal carotid artery elasticity. Methods For patients with BRVO who presented to Beijing Friendship Hospital between January 2014 and November 2014, 92 eyes of 92 patients were assigned as the participants,56 patients with BRVO were assigned as the BRVO group,36 patients were enrolled as control.All the participants were examined with color Doppler ultrasonography, these indexes were systolic diameter(Ds),diastolic diameter(Dd), peak systolic velocity(Vs), end diastolic velocity(Vd),mean velocity(Vm),intima-media thickness(IMT) and plaque formation.These values were calculated:the internal carotid artery elastic parameters by relevant formula; wall motion degree(ΔD),arterial tension,arterial expansion,pressure-strain elastic modulus(Eρ),stiffness index(β),arterial compliance(AC)and resistance index(RI), internal carotid artery elasticity parameters and other index.Results Carotid plaque detection rate,internal carotid artery stenosis rate and intima-media thickness(IMT)of BRVO group were significantly higher than those of control group(P<0.05),wall motion degree(ΔD),arterial tension,arterial expansion,pressure-strain elastic modulus(Eρ),and arterial compliance(AC)of BRVO group had significant differences compared with control group(P<0.05), resistance index(RI), mean velocity(Vm) and stiffness index (β) of BRVO group have no significant differences compared with control group(P>0.05).Conclusion The detection of carotid artery hemodynamic parameters for patients with branch retinal vein occlusion is important, there is a relationship between BRVO and internal carotid artery elasticity.

Key words: branch retinal vein occlusion, internal carotid artery, artery elasticity parameter
