Influence of PTGS1, PTGFR, and MRP4 genetic variants on intraocular pressure response to latanoprost in Chinese primary open-angle glaucoma patients

Purpose The purpose of this study is to evaluate the association between variants in prostaglandin-endoperoxide synthase 1 (PTGS1), prostaglandin F (2α) receptor (PTGFR), and multidrug resistance protein 4 (MRP4) genes and intraocular pressure (IOP) response to latanoprost in Chinese patients with primary open-angle glaucoma (POAG).
