To evaluate the long-term course of intraocular pressure (IOP) after 20 gauge pars plana vitrectomy (PPV).
Retrospective, consecutive, interventional case series. One hundred and six eyes of 106 patients with idiopathic macular hole (n=46) or idiopathic epiretinal membrane (n=60) who underwent 20 gauge PPV between December 2001 and March 2005 were enrolled. The IOP profile in vitrectmized and fellow control eyes was compared at postoperative at 3, 6, 12, 24, 36, 48 and 60 months.
All patients were followed up for more than 12 months. There was no significant difference in postoperative IOP at any time between the virectmized and fellow eyes. Two vitrectomized eyes had an elevation of IOP exceeding 21 mmHg at 6 and 12 months. There was no glaucomatous optic disc and retinal appearance at any time in all patients.
A 20 gauge PPV did not have an apparent effect on the postoperative IOP.
