Computational fluid dynamics (CFD) simulation analysis on retinal gas cover rates using computational eye models

Abstract We investigated the change in the retinal gas cover rates due to intraocular gas volume and positions using computational eye models and demonstrated the appropriate position after pars plana vitrectomy (PPV) with gas tamponade for rhegmatogenous retinal detachments (RRDs). Computational fl...
