Optical intraocular pressure measurement system for glaucoma management

Abstract

This paper reports on ex-vivo studies with rabbit eyes using an optical intraocular pressure (IOP) measurement system. The system consists of an optical reader and a miniaturized interferometric pressure sensor integrated onto a standard intraocular lens. The results show that the measurement sensitivity of the sensor is on the order of 22 nm/mmHg with an accuracy of ±0.5 mmHg post implantation. The optical method developed is a promising approach for monitoring intraocular pressure for glaucoma patients. The portability of the measurement system may allow patients and physicians to conveniently obtain measurements in a patient point-of-care setting or a clinical environment.
