Acoustic excitation of the eye for measuring the intraocular pressure

Measuring intraocular pressure can be helpful in the early detection of glaucoma, as elevated pressure is a risk factor. However, diurnal fluctuations often go undetected with conventional tonometers. For this reason, a tonometer is being developed, that measures the pressure contactless through acoustic excitation and optical oscillation measurement, allowing those affected to take measurements themselves several times a day.

The aim of this work is to investigate the acoustic excitation for generating a signal suitable for analysing oscillation parameters such as amplitude and frequency. For that, research should be carried out to identify a suitable eye model and the acoustic excitation should be optimised.
