The aim of this study was to determine the relationships between lens opacity, vascular and lipid factors and retrobulbar blood flow parameters in type-1 diabetic (DM) adolescents.
MATERIAL/METHODS: Glycated haemoglobin (HbA1c), total cholesterol (TCH), high- and low-density cholesterol, triglycerides (TG) and apolipoprotein B (ApoB) were determined in 28 patients with (DM-1) and without (DM-0) lens opacity and 18 controls. In the ophthalmic, central retinal (CRA) and temporal posterior ciliary (TPCA) arteries, the systolic (PSV), end-diastolic and mean blood flow velocities as well as pulsatility and resistance (RI) indices were measured.
Ten (35.71%) diabetic patients exhibited lens opacification. Higher TG and TCH levels in the DM-1 group and HbA1c level in the DM-0 and DM-1 groups were observed (P≤0.05). Diabetic patients had lower PSV and higher RI within CRA and TPCA (P≤0.05). Significant correlations between biochemical and blood flow parameters were found.
Glycaemic and lipid factors may play a vasoconstrictive role in retrobulbar endotheliopathy.
本研究旨在确定1型糖尿病(DM)青少年晶状体混浊、血管和脂质因素与球后血流参数之间的关系。
材料/方法:对28例有(DM-1)和无(DM-0)晶状体混浊的患者以及18名对照者测定糖化血红蛋白(HbA1c)、总胆固醇(TCH)、高密度和低密度胆固醇、甘油三酯(TG)和载脂蛋白B(ApoB)。在眼动脉、视网膜中央动脉(CRA)和颞侧后睫状动脉(TPCA)中,测量收缩期(PSV)、舒张末期和平均血流速度以及搏动性和阻力(RI)指数。
10例(35.71%)糖尿病患者出现晶状体混浊。观察到DM-1组的TG和TCH水平较高,DM-0组和DM-1组的HbA1c水平较高(P≤0.05)。糖尿病患者CRA和TPCA内的PSV较低,RI较高(P≤0.05)。发现生化参数和血流参数之间存在显著相关性。
血糖和脂质因素可能在球后内皮病变中起血管收缩作用。
