Intraocular Pressure Accuracy and Variability of the Barraquer Tonometer
May 6, 2008 updated by: Barnes Retina Institute
Study to Compare the Accuracy and Variability of the Barraquer Tonometer With Other Methods of Tonometry
To determine if the Barraquer tonometer provides an accurate and reliable measurement of intraocular pressure.
The Barraquer tonometer is a device used to safely and painlessly measure intraocular pressure.

Detailed Description
Intraocular pressure will be checked using four different methods of tonometry.
These four methods will include Tonopen, Goldmann applanation tonometry, Schiotz tonometry, and Barraquer tonometer.
The data will then be compared to determine the reliability and accuracy of the Barraquer tonometer.
