Abstract: The risk factors of high intraocular pressure (IOP) after pars plana vitrectomy(PPV) are various, mainly related to the complexity of disease and intraocular tamponade. So we need to control the high IOP after vitrectomy according to the high risk factors and the pathogenesis. Moreover, screening high-risk population before operation, choosing appropriate surgical procedure, and monitoring IOP after operation will be helpful to reduce the occurrence of high IOP. Once high IOP after vitrectomy happens, symptomatic treatment, anti-glaucoma medication or surgery should be performed as soon as possible in order to protect optic nerve and visual function.
