Correlation Of Retinal Vein Occlusion With Blood Lipids And Carotid Artery Changes

BackgroundRetinal vein occlusion is second only to diabetic retinopathy of the second most common retinal vascular disease, if not treated, will damage to visual function, cause vision loss.RVO occurs mostly in the elderly, men and women all can come on, often for monocular involvement, around eyes no difference. As people living standard rise, the incidence of retinal vein occlusion is on the rise in recent years, as well as the occurrence and development of RVO risk factors have a deeper understanding, including systemic disease, cardiovascular disease, systemic disease, ocular factors, such as age, living habits, drug, As well as a variety of causes systemic disease are related to vessel wall, blood composition and hemodynamic changes. Discover the risk factors of RVO happened and make related prevention to high-risk groups, is particularly important in the modern medicine.ObjectiveTo investigate the correlation of retinal vein occlusion (RVO) with blood lipids and carotid artery changes.Methods40 cases (40 eyes) with RVO who presented to Eye Hospital of Xinxiang Medical University between May 2013 and April 2014 were selected as the research object. Proceeded blood lipids and color doppler ultrasonography examination, including total cholesterol(TC), triglycerides(TG), high-density lipoprotein cholesterol(HDL-C), low density lipoprotein cholesterol(LDL-C), Common carotid artery intima-media thickness, carotid plaques, internal carotid artery blood flow mechanics parameters were detected.30 eyes (30 cases) were enrolled as control.ResultsTC, TG, LDL-C of RVO group was obviously higher than that of the control group(P<0.05), while HDL-C level was obviously lower than that of the control group (P<0.05. incidence of carotid artery plaque formation in RVO group was obviously higher than that in the control group. Entima-media thickness(IMT) of common carotid artery was obviously increased in RVO group (P< 0.05). Both peak systolic velocity (PSV) and end diastolic velocity (EDV) of internal carotid artery reduced (P< 0.05), and Resistance index(RI) increased (P<0.05). The eyes of the sick side and the contralateral carotid artery measured value had no statistical difference (P> 0.05). There were also no statistical difference between ipsilateral and contralateral carotid artery measured value of control group (P>0.05).There were no differences in age, sex between RVO group and control group(P>0.05).ConclusionsLipid metabolism disorder, carotid artery changes is closely related to the pathogenesis of RVO.
