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 has been published that examines clinically relevant outcomes in glaucoma in relation to three different forms of tonometry. Goldmann, Corneal Compensated IOP (IOPcc), and Rebound tonometry were evaluated in open-angle glaucoma patients. This study showed that not all IOP readings are equivalent. 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%). These results indicate that IOPcc readings may be a better risk factor for glaucoma.
