摘要

摘要: 眼科中治疗孔源性视网膜脱离(RRD)的玻璃体切割联合硅油填充术中，预测术后硅油乳化情况，并根据其确定术中适宜硅油填充量和最终取出时间是手术成功的关键。然而手术流程中医生无法直接观察眼球内部结构，很难对填充物质进行定量分析，手术完成后亦对硅油乳化状态缺乏可视化认知。该文提出一种基于光滑粒子流体动力学的体积不可压缩多相流体计算框架，结合表面张力模型对眼内环境中硅油和水的耦合进行数值计算；构建以力平衡散体动力学模型为基础的多相流体互溶扩散模拟方法，对硅油乳化过程进行可视量化分析。实验表明，该方法可以稳定模拟强表面张力作用下多相流体耦合以及可混溶多相流体相间交互效果，从而有效辅助医生判定所需硅油填充量，并预测评估硅油乳化状态对手术预后的影响。

Abstract: In vitrectomy combined with silicone oil tamponade for the treatment of Rhegmatogenous Retinal Detachment(RRD) in ophthalmology, the prediction of postoperative silicone oil emulsification, the appropriate amount of silicone oil filling and the final removal time are the key to the success of the operation. However, doctors can not directly observe the internal structure of the eyeball during the operation process, and it is difficult to analyze quantitatively the filling materials. After the operation, there is also a lack of visual cognition of the emulsification state of silicone oil. In this paper, a volume incompressible multiphase fluid computational framework based on Smooth Particle Hydrodynamics is proposed to calculate numerically the coupling of silicone oil and water in intraocular environment, combined with the surface tension model. A multiphase fluid miscible diffusion simulation method based on the force-balanced dispersion dynamics model is constructed to analyze visually and quantitatively the silicone oil emulsification process. Experiments show that this method can simulate the multiphase fluid coupling under strong surface tension and interphase interaction of miscible multiphase fluid stably, so as to assist effectively the doctors to determine the amount of silicone oil required before operation, and predict and evaluate the influence of silicone oil emulsification state on the prognosis of operation.
