Comparison of Intraocular Pressure Measurements Between Icare PRO, Icare ic200, and Goldmann Applanation Tonometer
In Brief
An observational study evaluating Icare Tonometer for Intraocular Pressure. Completed, enrolled 101 participants across 1 site.
Detailed Summary
Intraocular pressure measurement (IOP) is part of a routine eye examination. High and low eye pressure may be linked to certain eye conditions such as glaucoma. The current gold standard for IOP measurement is a technique called Goldmann Applanation Tonometry (GAT). GAT requires the use of a Goldmann applanation tonometer mounted on a slit lamp. Apart from GAT, there are many other devices that can be used to measure IOP, including the iCare tonometers. In this prospective study, investigators will be measuring participant's IOP with GAT, Icare PRO, and Icare ic200 tonometers to see if there is an agreement in IOP between the different devices. Investigator will also look if there is a concordance between different tonometers in low, moderate and high IOP range. Given the postural requirements for performing GAT, patients with higher body mass index (BMI) tend to have difficulties with proper positioning at the slit lamp that may lead to inaccurate GAT measurements. To this end, investigators will analyze the effect of BMI on IOP measurements with different devices. Additionally, comfort level of the patients with different tonometry devices will be recorded using a visual analog scale.

Interventions
Icare tonometers are a new class of rebound tonometers for IOP measurements. The Icare series of tonometers are hand-held tonometers, which are easy to operate and generally do not require topical anaesthesia for IOP measurements.
