Visual Field Progression Rates and Intraocular Pressure Measurements with Different Tonometers

IOPcc explained more than two times the variance of rates of change in our sample compared to GAT, and this most likely represents the fact that IOPcc measurements are more closely related to the true IOP measurements in the eye.”

A new study that examines clinically relevant outcomes in glaucoma in relation to three different forms of tonometry has been published. Goldmann, Corneal Compensated IOP (IOPcc), and Rebound tonometry were examined in open-angle glaucoma patients. IOPcc had the strongest association with visual field loss (24.5%); more than double the association of Goldmann applanation tonometry (11.1%), and more than four times that of Rebound tonometry (5.8%). This indicates that IOPcc is a valuable measurement for glaucoma management.
