We are testing the accuracy of Reichert's Tono-Vera tonometer by comparing measurements of IOP with this device and measurements with other commonly-used tonometers, including Goldmann Applanation and iCare.
Ability to provide signed and dated informed consent form. Patients willing to comply with all study procedures and be available for the duration of the study.
Patients age less than 18 years Patients unable or unwilling to provide informed consent to participate in the study Patients for which an accurate tonometry reading cannot be performed. This may include those with blepharospasm (lid squeezers), nystagmus, extensive corneal pathology, or contact lens wearers who cannot remove their contact lens.Patients with significant scleral thinning Patients with a known allergy to proparacaine or fluorescein as these are used to anesthetize and allow measurement respectively of the eye when used with the Goldmann tonometer.
Single group
Tono-Vera tonometer
DeviceThe tonometer measures intraocular pressure with a small rebound probe, similar to those used with other tonometers currently on the market, such as the iCare.
Goldman Applanation Tonometry
DeviceThis is the current gold standard for measuring eye pressure.
Intraocular Pressure
pressure inside the eye
