Automated applanation tonometry to measure eye pressure

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective comparison of two investigational applanation methods against Goldmann applanation tonometry (GAT) and pneumotonometer readings in adults presenting for routine eye care. After informed consent, intraocular pressure measurements will be taken by standard GAT, a pneumotonometer, a fixed-force GAT with a CMOS camera recording the mire diameter, and an upright applanating prototype. The fixed-force approach uses a preset GAT force while video captures mire size for automated calculation of IOP, and the study will compare reproducibility and agreement across methods. The goal is to determine whether the investigational methods deliver more objective, repeatable, and portable IOP measurements than current clinical standards.
