measuring the intraocular pressure (IOP), the fluid pressure inside the eye. It is an important test in the evaluation of patients with glaucoma, as damage to the optic nerve is more likely to occur in patients with high IOP. Most tonometers are calibrated to measure pressure in millimeters of mercury (mmHg). Goldmann tonometry is considered to be the gold standard test for IOP and is the most ...

متن کاملStandardized x-tonometers.
STANDARDIZED Schi6tz tonometers of the original (weighted) type have been on sale in the United States for more than 10 years, and a considerable amount of information has been collected which bears out the acceptability of the current specification. This knowledge was assembled in the First Decennial Report of the Committee on Standardization of Tonometers (1954). Following the American lead, ...
متن کاملTonometry and Care of Tonometers
Intraocular pressure (IOP) remains the only modifiable risk factor in the management of glaucoma. Hence, IOP and its appropriate measurement deserve our ongoing interest. Over the years, not only has our understanding of glaucoma changed but also has changed our approach to the measurement of the IOP. This review is an attempt to elucidate the commonly techniques of tonometry, and critically ev...
