Tonometry

In an adult subject, the ocular pressure normally ranges between 15 and 16 mm of mercury; values between 12 and 19 mm of mercury are still considered in the normality range. The measurement of intraocular pressure is a simple and quick diagnostic technique which is absolutely not traumatic for the patient. Usually, this examination is performed with an applanation tonometer that touches briefly the apex of the cornea after instillation of a drop of anaesthetic. We recommend completing tonometry with “pachymetry” of the cornea for maximum reliability of the examination.

Our centre is also equipped with portable tonometers and with a tonometer that, where appropriate, can be used at home by the patient himself for a correct evaluation of the pressure changes during the day. The data stored will then be evaluated by our doctors.
