To measure intraocular pressure on your own, you need to go through the finger-prick method, which is not a very accurate method of checking, but only estimates whether there is any abnormality in intraocular pressure by feeling. It can be detected by non-contact tonometer, pressure-induced tonometer and pressure-flat tonometer. 1. Non-contact tonometer: Non-contact tonometer tests do not require contact with the eyes and utilize pneumatic principles to detect intraocular pressure. 2. Sunken tonometer: The area to be tested needs to be anesthetized before the test, and the meter is placed in the central area of the cornea to detect the level of intraocular pressure. 3. Piezometric tonometer: Piezometric tonometer is the most accurate method of detecting intraocular pressure, which is called the gold standard of intraocular pressure. However, the process of detection is more cumbersome, and it is suitable for glaucoma patients to do 24-hour intraocular pressure monitoring. If you feel that there is a problem with your intraocular pressure, it is recommended that you consult a doctor in a timely manner and follow the doctor’s instructions.
