Objective: To determine the accuracy of the EYEMATE-SC suprachoroidal tracer for telemetric tonometry in canine and equine globes.
Procedures: The EYEMATE-SC sensor (7.8 mm × 3.

Objective: To investigate short- and long-term intraocular pressure (IOP) fluctuations in patients with primary open-angle glaucoma (POAG) after successful nonpenetrating glaucoma surgery (NPGS).
Design: Prospective, open-label, multicenter interventional study.
Subjects: A total of 20 patients with POAG who underwent NPGS combined with permanent implantation of a suprachoroidal telemetric IOP sensor (EyeMate-SC, Implandata Ophthalmic Products GmbH, Hanover, Germany).

Background: Due to technical limitations of commonly used tonometry devices, the effects of physical exercise on intraocular pressure (IOP) have never been studied during exercise. This study continuously monitored IOP variations in patients with glaucoma during physical exercise using an implanted IOP microsensor.
Methods: In total, 10 participants (six male and four female) with open-angle glaucoma (age range: 67-79), previously implanted with an IOP sensor, were included.

Purpose: To evaluate the long-term safety and performance of the EYEMATE-SC sensor system, a suprachoroidal implantable diagnostic medical device designed for measuring intraocular pressure (IOP) in patients with glaucoma that offers direct digitized IOP readings in millimeters of mercury.
Design: This study is part of the prospective, open-label, multicenter interventional EYEMATE-SC trial.
Participants: Twenty-two eyes of 22 patients with open-angle glaucoma who received the implant in conjunction with nonpenetrating glaucoma surgery (NPGS) were included in the study.

Intraocular pressure (IOP) and cerebrospinal fluid pressure (CSFP) telemetry in large animal models can be used to determine the exact IOP, CSFP, translaminar pressure, and translaminar pressure gradient exposure that each normal and treated eye is subjected to relative to its fellow eye. In this way, it is possible to determine the independent contributions of each of these parameters (mean and/or transient fluctuations) to the risk of both the onset and rate of progression of glaucoma. Importantly, we have shown that IOP and CSFP fluctuate continuously by up to 100% over the course of the day, so snapshot cage-side IOP measurements are unable to adequately capture the pressure in the eye; CSFP is not measurable noninvasively at all.
