The objective of this study is to analyze subretinal liquid dynamics by means of numerical simulations in patients with retinal detachment after insertion of intussusception. The main parameter being analyzed is the outflow velocity of subretinal fluid through the hole in the retina. All calculations were performed using FEM and the results were evaluated in relation to the velocity of outflow when considering parameters such as; i) speed of eyeball movement, ii) shift of intussusception in relation to the center of the hole in the retina, iii) viscosity of the subretinal fluid. Results obtained suggest an optimal speed of eyeball movement for patients to achieve maximal speed of outflow of subretinal fluid. This is a significant factor in achieving improved clinical outcomes for patients.
