Patients who are found to have elevated IOP on non-contact tonometry testing are expected to have Goldman or Perkins applanation tonometry pressure refinement carried out at the same visit.
The IOP measured by the gold standard method, Goldmann Applanation Tonometry (GAT) is based on the assumption that CCT is 520 [micro]m.
27 mm/min, and mean intraocular pressure measured via applanation tonometry was 10.
All of the participants had a detailed ophthalmological examination including tonometry using Goldmann applanation tonometry and RNFL analysis using optical coherence tomography (RTVue-100 5.
The following data were extracted from medical records: age, sex, type of glaucoma, visual acuity measurements when available (before and after surgery), details of slit lamp examination or under the operating microscope (before and after surgery), IOP measurement obtained with Perkins or Goldmann applanation tonometry (before and after surgery), optic disk and fundus evaluation, and axial length measurements when available (before and after surgery).
Pre-operatively, a complete ophthalmic examination including a Fluorescein dye test, Schirmer's tear test (STT), applanation tonometry, tests of blindness, direct and indirect ophthalmoscopy were performed in all dogs of both groups.
During the exit visit, subjects underwent anthropometric measurements, office blood pressure measurements, and indicators of arterial stiffness and applanation tonometry.
Parameters of arterial stiffness and wave reflection were assessed by applanation tonometry (SphygmoCor, AtCor Medical, version 8.
of medical history, Snellen visual acuity testing, slit-lamp biomicroscopy, Goldman applanation tonometry, and cornea topography.
New techniques such as radial artery applanation tonometry [9] are also promising.
In order to diagnose POAG Intra ocular pressure (IOP) was measured by means of Applanation tonometry and then was confirmed through perimetry and ophthalmoscopes.
