About this study

In plain language

This study compares two new ways to measure eye pressure with two standard tests. The goal is to develop tests that give more consistent results, rely less on personal judgment, and are easier to carry. It is for adults coming in for a routine eye exam.

Goldmann Applanation Tonometry (GAT) is considered the clinical gold standard for eye pressure measurements and yet it is known to be a subjective measurement with limited repeatability and limited portability. Another clinical standard for checking eye pressure is known as the pneumotonometer. This method is more objective but not portable. The purpose of this study is to develop new methods of measuring eye pressure that are more objective, reproducible and portable. In this study, the investigators will be comparing the eye pressure measurements using 2 investigational methods to GAT and pneuumotonometer.

Compensation is read from the study's own description and may be missing — always confirm with the study team.
