  • 摘要: 研究眼内房水流动有助于认识眼睛疾病(如青光眼)发生机理.该文利用计算流体力学计算了人眼睫状体分泌的房水由后房流经5μm和30μm虹膜-晶体间隙进入前房,再经小梁网排出这一过程,分析了平视、仰视、俯视不同体位以及不考虑浮力因素的眼内房水流场.结果表明不同情况的房水压力场类似,5μm虹膜-晶体间隙时后房眼压比前房约高30 Pa,而30μm时前后房压力基本相同,小梁网压力下降明显.前后房压差驱动房水从后房流经虹膜间隙到前房,而角膜与虹膜温差引起的自然对流为前房房水的主要流动.前房自然对流引起的压差变化在mPa量级,温度较高房水汇集区域压力稍高.平视时主要为前房虹膜侧房水上升、角膜侧下降的自然对流循环;仰视时瞳孔区房水沿前房中心轴上浮,然后沿角膜向周边下沉,从虹膜周边部回到瞳孔,形成轴对称的对流模式;对于俯视,流动模式与仰视正好相反,前房中心轴上房水从角膜运动到瞳孔处;不考虑浮力作用时,房水的平均速度比自然对流时小1~2个数量级.
