Not Applicable

Completed

• Conditions: Intraocular Pressure

• Registration Number: NCT01786954
• Lead Sponsor: Duke University

Brief Summary

The purpose of the study is to compare the measurement of pressure inside the eye using three different FDA-approved devices (Icare, Tonopen, and Goldmann applanation).

Detailed Description

The three above devices will be used to measure intraocular pressure in patients one day following vitreoretinal surgery. The underlying reason for surgery is not being considered in this study. The measured pressures will be compared across devices in eyes filled with fluid, gas, and silicone oil.
