The second-generation University of Alabama at Birmingham IOP telemetry implant. (A) Photograph of enhanced second-generation Konigsberg Instruments T27G total implant system for continuous monitoring of bilateral IOP, bilateral electrooculogram (EOG), aortic blood pressure, and body temperature. (B) A 23-gauge silicone tube delivers aqueous from the anterior chamber to a fluid reservoir on the intraorbital side of the transducer; the tube (with appropriate slack to allow for eye movement) is trimmed, inserted into the anterior chamber, sutured to the sclera using the integral scleral anchor plate, and covered with a corneal patchgraft (not shown).
