Abstract:
Purpose. To evaluate the intraocular pressure (IOP) with three different instruments, Goldmann applanation tonometer (GAT), noncontact tonometer, and Tono-Pen after photorefractive keratectomy (PRK) for myopia.

Comparison of intraocular pressure measured by non-contact air puff versus Goldmann applanation tonometers in gas-filled vitrect

Submitted by dave on Fri, 12/15/2006 - 3:43pm

OBJECTIVE: To compare intraocular pressure (IOP) measured by two different instruments, air puff tonometer (NCT) versus Goldmann applanation tonometer (GAT), in gas-filled vitrectomized eyes.

DESIGN: Three-month, prospective, comparative trial.

Assessment of the accuracy and reliability of the Topcon CT80 non-contact tonometer.

Submitted by dave on Fri, 12/15/2006 - 2:18pm

BACKGROUND: The reliability of non-contact tonometers has been reported extensively in the literature. This study was designed to assess reliability of the new Topcon CT80 non-contact tonometer in normotensive subjects, using the Goldmann tonometer as the standard.

Comparison of the ICare((R)) rebound tonometer with the Goldmann applanation tonometer by experienced and inexperienced tonometr

Submitted by dave on Fri, 12/15/2006 - 2:15pm

 

Purpose: To assess the agreement between ICare((R)) rebound tonometer and Goldmann applanation tonometer in the hands of experienced and inexperienced tonometrists.

Patients and methods: Two tonometrists, experienced with both Goldmann applanation tonometry (GAT) and ICare(R) Tonometry (ICT) measured intraocular pressure (IOP), in a masked fashion, in 100 patients. In another series of 58 patients, ICT was performed by an inexperienced tonometrist and GAT by an experienced tonometrist.

Inter-instrument agreement and influence of central corneal thickness on measurements with Goldmann, pneumotonometer and noncont

Submitted by dave on Fri, 12/15/2006 - 2:11pm

PURPOSE: This study was conducted to compare the intraocular pressure (IOP) measurements by the Goldman applanation tonometer (GAT), non contact tonometer (NCT) and the ocular blood flow (OBF) pneumotonometer in different IOP ranges in glaucomatous eyes. The effect of central corneal thickness (CCT) on IOP measurement in chronic glaucomatous eyes using the three different tonometers was also evaluated.

Reproducibility of dynamic contour tonometry. Comparison with TonoPenXL and Goldmann applanation tonometry - a clinical study on

Submitted by dave on Fri, 12/15/2006 - 2:09pm

BACKGROUND: The PASCAL Dynamic Contour Tonometer (DCT) is a new diagnostic approach for the digital measurement of intraocular pressure (IOP) in eyes with glaucoma. The aim of this study was to evaluate the reproducibility of DCT in normal eyes and to compare DCT with Goldmann applanation tonometry (GAT) and TonoPenXL.

Breathing "Right" Lowers IOP In Study

Submitted by dave on Sat, 12/09/2006 - 8:59pm

As I understand this study, the researchers had subjects with primary open angle glaucoma (POAG) breathe through their right nostril only (by closing off their left nostril). There is a common breathing technique in Yoga know as "alternate nostril breathing" or Nadi Shodhana in sanskrit. The aim of alternating the open nostrils is to create balance in the physiology. The idea behind the method used in this study is to correct a (perceived) imbalance by breathing through the right nostril only.
