Intraocular Pressure Monitoring Using an Intraocular Sensor Before and After Glaucoma Surgery

Abstract

Purpose: Intraocular pressure (IOP) is the only modifiable risk factor for glaucoma, with evidence from landmark randomized controlled trials demonstrating visual field preservation with IOP reduction. Over recent years, the use of remote sensors has formed an increasingly important component of the management of chronic diseases. During the coronavirus disease 2019 pandemic, the ability to remotely monitor IOP proved particularly useful when public stay at home orders have been in place.Patients and Methods: This report describes the first case of glaucoma surgery in a patient who had previously received an EYE-MATE-IO implant. The EYEMATE-IO is an implant for IOP monitoring placed in the ciliary sulcus during cataract surgery.Results: Remote IOP monitoring enabled the clinician to identify sustained high IOP readings and the need for glaucoma surgery. Postoperatively, response to treatment could be monitored to ensure sufficient long-term IOP control. Conclusion:The EYEMATE-IO implanted during cataract surgery in this patient provided valuable remote continuous IOP information that guided timely glaucoma surgical interventions for poorly controlled IOP.

Real-Time Monitoring of Intraocular Pressure in Glaucoma Patients Using Wearable Mobile Medicine Devices

“…The intraocular pressure signal is obtained by measuring the phase frequency shift of the external coil impedance. The transmission distance between the sensor implanted in vivo and the signal received in vitro can reach 6 mm, the relative sensitivity of the sensor in air can reach 7035 ppm/mmHg, and the relative sensitivity in normal saline can reach 3770 ppm/mmHg [ 19 ].…”

Micro-/Nano-Structured Biodegradable Pressure Sensors for Biomedical Applications

“…Despite of the recent development in biodegradable pressure sensors, there are still some issues, such as sensitivity, operating range, and controllability of biodegradability, essentially to be improved for accurate pressure monitoring of various tissues and organs. In other words, regarding there are huge recent demands for healthcare and diagnosis of diseases in early stage through the pressure sensing of diverse tissues and organs, such as intracranial pressure [ 152 , 153 , 154 , 155 , 156 , 157 ], intraocular pressure [ 158 , 159 , 160 , 161 , 162 , 163 ], heartbeat [ 164 , 165 , 166 ], and bladder pressure [ 167 , 168 , 169 , 170 ], we expect that the high-performance biodegradable pressure sensors will be much more important for diverse biomedical applications in the future.…”
