Influence of pars plana vitrectomy for macular surgery on the medium term intraocular pressure.

ABSTRACT:

Purpose

To evaluate the long-term effect of 20 and 23 gauge pars plana vitrectomy (PPV) on intraocular pressure (IOP).

Methods

Study type: Monocentric retrospective cohort study. 249 eyes of 249 patients undergoing PPV due to epiretinal membrane (EM), idiopathic macular hole (IMH) or vitreoretinal traction (VT) were included. The fellow eye served as control. Exclusion criteria were factors known to influence the IOP, such as cataract surgery during follow-up, extended use of steroids, cryotherapy and silicone oil endotamponade. The relative change of IOP (operated vs. fellow eye) at 6-12 months after surgery was defined as primary endpoint. Secondary endpoints were the relative change of IOP at 3-6 and 12-24 months. Possible influencing cofactors were analysed using ANCOVA.
