A lot of strategies have been proposed since the development of the 1st tonometer in 1863 by von Graefe.[9] These quite a few methods are depending on distinctive ideas of physics to get an estimate of your correct IOP, which all purpose for being exact, particular, and consultant of the particular you can find out more IOP that is of utmost relevance in the management of clients in a program medical placing.
