Numerical simulation of suprachoroidal shunts for treatment of glaucoma

A numerical investigation of Aqueous Humor (AH) flow in SOLX® Gold Micro Shunt (GMS) and a novel Silicon Shunt Device (SSD) is presented, with the aim of reducing IntraOcular Pressure (IOP) for treatment of glaucoma. The generalised porous medium model is solved to simulate AH flow through the devices and the surrounding tissues. In the GMS, probable stagnation regions were found, due to very small AH velocity values and to the surrounding tissues, creating blockage and malfunction of the device. The simple microtubular geometry of the novel SSD allows to have a regular AH flow and facilitates surgeons in the choice of shunts with different diameter, based on patients needs, avoiding post-operative complications
