Modeling of Transpalpebral Tonometry System for Parameters Optimization of the Measuring Sensor

摘要

This paper presents the method of intraocular pressure (IOP) determination by transpalpebral tonometry (TPT), especially for the diagnosis and the control of glaucoma. TPT can be preferred method for determining IOP in terms of minimizing the contact of the measuring device with the surface of the eye. The biomechanical basis of transpalpebral tonometry is briefly discussed. The two possible schemes of TPT technique which includes a stem with springs as measuring sensor are presented. Modeling of TPT system for parameters optimization of the measuring sensor in case the dynamic measurement method is described. The researches conducted with various combinations of stem weight and diameters are presented for IOP in the range from 10 to 30 mmHg.
