An implantable intraocular pressure transducer: initial safety outcomes.
IMPORTANCE To our knowledge, this is a report of the first implantation of a wireless intraocular pressure transducer (WIT) in a human eye. OBJECTIVE To report preliminary safety data on the WIT. DESIGN, SETTING, AND PARTICIPANT In an institutional setting, a patient with open-angle glaucoma consented to be the recipient of the WIT in one eye in an interventional study design. INTERVENTIO...
متن کاملImplementation of an implantable joint-angle transducer.
An implantable joint-angle transducer (IJAT) was implemented to provide command-control information from the wrist for functional neuromuscular stimulation (FNS) neuroprostheses. The IJAT uses the Hall effect to sense joint angle. The objectives of this study were to evaluate (1) chronic functionality, (2) safety and biocompatibility, (3) repeatability of the implantation procedure, and (4) cli...
متن کاملNanoarray-enhanced Implantable Intraocular Pressure Sensor with Remote Optical Readout
We demonstrate a compact implantable intraocular pressure sensor with remote optical readout for glaucoma research and patient management. Using broadband white light between 7801150nm, we excite the sensor’s pressure-sensitive optomechanical cavity and detect the reflected light, whose optical signature changes as a function of intraocular pressure. When measured inside an artificial pressure ...
متن کاملDetermination of Central Venous Pressure from Intraocular Pressure
Background: In many clinical situations, knowledge of central venous pressure (CVP) is important. Measurement of CVP is not always possible. Objective: To determine if intraocular pressure (IOP) can be used as an estimate for CVP. Methods: IOP and CVP were measured concurrently in 30 candidates of coronary artery bypass graft surgery. Those with carotid artery or jugular venous diseases as we...
متن کاملIntraocular pressure
The tissue pressure of the intraocular contents is called the intraocular pressure (IOP). The normal range for IOP is 10–20 mm Hg and is maintained at this level throughout life and between the sexes, though there is some diurnal and seasonal variation. Control of IOP within the correct physiological range is necessary to maintain the anatomical conditions necessary for optimal refraction and t...
