What this Trial Is About

Researchers are evaluating new methods to measure eye pressure more objectively, reproducibly, and portably compared to the current clinical standards. The study focuses on comparing two investigational devices with Goldmann Applanation Tonometry (GAT) and pneumotonometer, which are standard methods used to check eye pressure. This research is important for patients undergoing eye exams, especially those suspected of glaucoma or with glaucoma, to improve measurement accuracy and convenience. Participants will undergo four types of intraocular pressure (IOP) measurements in random order: standard GAT, fixed force GAT, an upright applanating prototype, and pneumotonometer. Standard GAT and pneumotonometer are established clinical methods involving topical anesthetic and direct eye contact. The fixed force GAT and upright applanating prototype are investigational devices that use cameras to record mire images and calculate IOP based on these images. The upright prototype is portable and uses blue LED lights to simulate standard clinical illumination. During the study, participants will have their IOP measured by each method during their scheduled eye appointment after giving consent. Researchers will track and compare the pressure readings from each device. The primary outcomes include IOP values measured by all four methods at baseline. This prospective study will help assess the repeatability and portability of the new devices compared to standard clinical tools, with no masking or blinding involved.
