OBJECTIVES Radial artery applanation tonometry allows completely noninvasive continuous cardiac output estimation. The aim of the present study was to compare cardiac output measurements obtained with applanation tonometry (AT-CO) using the T-Line system (Tensys Medical, San Diego, CA) with cardiac output measured by intermittent pulmonary artery thermodilution using a pulmonary artery catheter...

A tonography device, based on the MacKay-Marg tonometer, has been constructed which will applanate the cornea to a preselected area of 5.0 to 6.0 mm diameter and maintain that applanation area. The pressure decrease with time should resemble the pressure decrease following bolus injection of fluid into the eye. In most cases the pressure decreased in a linear slope, abruptly terminating in a pr...

BACKGROUND An accurate assessment of Intraocular pressure (IOP) is vital in establishing diagnosis of Glaucoma and decision making regarding various treatment modalities available. The purpose of this study is to compare Goldmann Applanation Tonometer (GAT) with Air puff tonometer. METHODS Cross-sectional comparative study conducted. 73 eyes from 73 patients were included in this study and in...

BACKGROUND: Introduction and use of various tonometry methods can lead to misinterpretation intraocular pressure results influence the choice treating approaches by ophthalmologist in a glaucoma patient.
 AIM: To compare pneumotonometry rebound with Maklakovs applanation develop corrections for their comparability.
 MATERIALS AND METHODS: The study included 75 patients. All subjects u...

OBJECTIVE WE AIMED TO COMPARE INTRAOCULAR PRESSURE (IOP) MEASUREMENTS VIA THREE DIFFERENT TONOMETERS: the Goldmann applanation tonometer (GAT), the Tono-Pen(®) XL (TPXL), and a non-contact airpuff tonometer (NCT). METHODS This was a cross-sectional study of 200 eyes from 200 patients. Right eyes of all patients were included in this study. IOP was measured via GAT, NCT, and TPXL by three phys...

The utility of Goldmann applanation tonometry (GAT) for monitoring intraocular pressure (IOP) in open-angle glaucoma (OAG) patients with a history of laser refractive surgery was investigated by comparing IOP fluctuations measured using GAT and dynamic contour tonometry (DCT) on the same day. In this retrospective study, patients were divided into one of two subgroups according to IOP fluctuati...

We prospectively compared dynamic contour tonometry (DCT) to Goldmann (GAT) and hand-held tonometry (HHT) in normal, ocular hypertension, and glaucoma populations. Both measurements were made on each patient within a 5-minute period during routine office exams over 4 months. While DCT is in good overall agreement with GAT and HTT, there is some systematic deviation at different pressure ranges ...
