Not Applicable

Not yet recruiting

• Conditions: Pars Plana Vitrectomy

• Registration Number: NCT06707168
• Lead Sponsor: Sunnybrook Health Sciences Centre

Brief Summary

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.
