Official title
ACCURACY of DIGITAL INTRAOCULAR PRESSURE MEASUREMENT AT the END of PARS PLANA VITRECTOMY SURGERY
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.
Interventions
- Diagnostic test Digital palpation
Digital palpation for IOP measurement - Diagnostic test Cotton-tipped applicator (CTA)
Cotton-tipped applicator (CTA) for IOP measurement
Primary outcome measures
- Intraocular pressure measurement [Time frame: From enrolment to end of treatment at 8 weeks]
Secondary outcome measures (1)
- Intraocular pressure measuring agreement [Time frame: From enrolment to end of treatment at 8 weeks]
Eligibility criteria
Inclusion criteria
- All patients undergoing Pars Plana Vitrectomy between June 25, 2024 - and December 30, 2024, will be included.
- Patients aged 18 years or older
- Patients able to give informed consent
Exclusion criteria
- Patients with complicated Pars Plana Vitrectomy (choroidal hemorrhage, retrobulbar hemorrhage)
- Patients with irregular cornea surface will be excluded (keratoconus, band keratopathy, corneal edema, corneal transplant, cornea scarring)
