Summary

In adult patients, intraocular pression readings are often taken with an air puff tonometer or goldmann tonometer. The current gold standard for IOP measurement is the Goldmann Applanation Tonometry (GAT). In some patients, measurement of intraocular pressure taken by applanation or by air puff may prove to be impossible for various reasons (obesity, handicap, mental disorder, blindness for Air Puff Tonometry, Anxiety, etc).

There are also many other devices that can be used to measure IOP, including those using rebound tonometry like the Icare 200.

The rebound tonometer would systematize IOP screening because of its ease of use, provided its measurements are reliable. In this prospective study, investigators will be measuring participant's IOP with Goldmann Applanation Tonometry, Icare 200 Tonometer and Air Puff Tonometry to see if there is an agreement in IOP between the different devices. Investigators will also look if there is a concordance between central corneal thickness and IOP. Moreover, investigators will look if there is a IOP concordance between the 3 different devices for hight BMI people. Indeed, higher body mass index tend to have difficulties with proper positioning at the slit lamp that may lead to inaccurate GAT measurements. Additionally, stress level of the patients with different tonometry devices will be recorded using a visual analog scale.
