Detailed intraocular pressure curve by telemetric tonometry with an implanted pressure sensor before and after PreserFlo ® MicroShunt implantation: a case report.

Continuous control of intraocular pressure (IOP) is crucial to preventing long-term damage to the optic nerve in glaucoma. Recently, a novel telemetric IOP sensor (EYEMATE-IO™, Implandata Ophthalmic Products GmbH, Hannover, Germany) has been developed that continuously records IOP. The patient can read the IOP measurements wirelessly using a hand-held reading device. We present the case of a 70-year-old patient with primary open-angle glaucoma who had been implanted with an EYEMATE-IO™ and recently underwent minimally invasive bleb-filtering surgery with the PreserFlo ® MicroShunt (Santen, Osaka, Japan). This case demonstrates both the benefits of continuous pressure measurement with EYEMATE-IO™ and the ability of the PreserFlo ® MicroShunt to significantly reduce IOP fluctuations.
