Intraocular Pressure Telemetry for Managing Glaucoma During the COVID-19 Pandemic

December 2020
IOP measurements acquired by the patients during the lockdown period were collected by physicians who were located remotely.
A questionnaire was sent to 10 participating study centers to evaluate the clinical impact of remote monitoring of IOP via the IOP sensor system.

The results show the feasibility of patient acquired measurement of IOP in conjunction with remote IOP monitoring by physicians as feasible with an implantable sensor.
The data obtained had an impact on clinical decision-making, including adjustment of ocular hypotensive therapy and avoiding unnecessary office visits during the COVID-19 pandemic.

Influence of electromagnetic radiation emitted by daily-use electronic devices on the Eyemate® system in-vitro: a feasibility study

September 2020
Background: Eyemate® is a system for the continual monitoring of intraocular pressure (IOP), composed of an intraocular sensor, and a hand-held reader device. As the eyemate®-IO sensor communicates with the hand-held reader telemetrically, some patients might fear that the electronic devices that they use on a daily basis might somehow interfere with this communication, leading to unreliable measurements of IOP….

Short-Term and Long-Term Variability of Intraocular Pressure measured with an Intraocular Telemetry Sensor in Patients with Glaucoma

July 2020
Continual IOP monitoring shows that IOP has moderate short-term and high long-term variability in glaucoma patients. These findings demonstrate that single IOP measurements do not characterize day to day variations in IOP. Moreover, they show the importance of continual IOP monitoring in glaucoma patients.

Using sensors to estimate intraocular pressure: a review of intraocular pressure telemetry in clinical practice

July 2020
With regards to the intraocular Eyemate monitor, its implantable nature reserves it for patients in more advanced stages of the disease. Less of a diagnostic test and more of monitoring tool, it is clear that simple and accurate self- monitoring of IOP has a strong potential to improve the care and follow-up of glaucoma patients…

Influence of electromagnetic radiation emitted by daily-use electronic devices on the Eyemate® System.

November 2019
Conclusion: Measurements made by the eyemate® system showed no apparent signal drift or evidence of being influenced by external electromagnetic radiation produced by the devices that we tested. Patients who already have the eyemate®-IO sensor implanted, and those who are considering to have one, should be informed that the electromagnetic radiation emitted by their daily-use electronic devices does not interfere with IOP measurements made by the eyemate® system.

Influence of physiological Parameters on IOP during physical activity - a Pilot study with the EYEMATE-IO™

June 2019
Accurate measurements of intraocular pressure by clinically available methods is typically limited to static situations in standard body positions. The aim of this pilot study was to employ a novel telemetric intraocular pressure sensor (EYEMATE-IO™, Implandata Ophthalmic Products GmbH, Hannover, Germany)for recording IOP during different body positions and physical activities.
Correlation between blood pressure, intraocular pressure and intracranial pressure – a pilot study

June 2019
To simultaneously measure intraocular pressure (IOP), intracranial pressure (ICP) and blood pressure (BP) variations in glaucoma patients previously provided with an implantable intraocular sensor (EYEMATE-IOTM), while inducing controlled
orthostatic pressure variations with the use of a tilt table.
