INTRAOCULAR PRESSURE MEASUREMENT AT the END of PARS PLANA VITRECTOMY

Sunnybrook Health Sciences Centre30 enrolled

Overview

Intraocular pressure is measured regularly at any and all visits with your eye doctor or optometrist. The purpose of this study is to compare measurements of eye pressure at the end of the surgery, comparing the ability of a gloved finger or sterile cotton-tipped applicator ("Q-tip") to accurately measure intraocular pressure against a standardized instrument designed for this purpose.
