Non-contact Tonometry Versus Pachymetry Corrected

WebHowever, the basis of any linear correction of IOP is unfounded, because the positive correlation between IOP measured with Goldmann applanation tonometry (Haag-Streit, Bern, Switzerland) and central pachymetry is very weak (R2≈0.17). Corneal biomechanics reflects more than central pachymetry. For example, IOP, as measured by Goldmann ... Web22 jun. 2024 · IOP is a dynamic parameter that can fluctuate 4-5 mmHg in healthy individuals and even more variably in glaucoma patients.
