If you are looking for a tonometry ppt, you have come to the right place. This article will go over the different types of tonometry ppts, as well as how to use them. This information is essential for your professional development. To get started with tonometry, read the following tips:
A PPT is an instrument used to measure intraocular pressure (IOP). A PPT is a device that is placed on the superior nasal portion of the eyelid with the surface tangential to the eyeball. It is applied to the patient’s eyelid with a gradual increase in force. The endpoint was when the patient’s eyelid appeared well-formed and had a central dark spot or a glowing outer rim.
The PPT is a good tool for measuring IOP in patients, but it’s important to remember that it cannot detect IOP higher than twenty-one mmHg. This makes it vital that patients seek ophthalmic care if the reading is greater than that. The PPT is portable, inexpensive, and requires no topical anesthesia. Moreover, it does not need direct contact with the eyeball and does not require a technician to perform the test.
Another important aspect of tonometry is the central corneal thickness (CCT). The central corneal thickness was estimated to be 520 microns by Goldmann in 1898, but there is a wide range in individual corneal thickness. A thick CCT can give an artificially high IOP reading, while a thin CCT can be misleading. There is still no perfect tonometer that will measure IOP.
