intraocular pressure measurement

Increased intraocular pressure is one of the causes of glaucoma. Conventional intraocular pressure measurement devices are difficult to use on a daily basis because they involve physical contact with the eyeball, such as deformation of the cornea. Therefore, we proposed a method to more easily measure intraocular pressure and designed a measurement circuit. Focusing on the correlation between corneal displacement associated with eye pulsation and intraocular pressure values, we measure corneal displacement using triangulation to achieve non-contact, non-applanation intraocular pressure measurement. In the lecture, we will report on the details of the measurement method and measurement circuit.
