| 20080242965 | Reflective non-contact ocular pulse analyzer for clinical diagnosis of eye and cerebrovascular disease - An instrument has been designed to study the pulsatile motion of the eye by analysis of a beam of light reflected from the corneal surface. A laser light beam probe of small spot size and low divergence strikes the cornea apex and the reflected movement is recorded by a sensor. Analysis of the beam movement reveals the energy in the eye pulse without the necessity of physically touching the eye. The value of the intraocular pressure is determined from the calculated power spectrum.

| 20160015266 | SYSTEMS AND METHODS FOR SENSING INTRAOCULAR PRESSURE - Systems and methods of sensing intraocular pressure are described. An example miniaturized intraocular pressure (IOP) monitoring system is provided using a nanophotonics-based implantable IOP sensor with remote optical readout that can be adapted for both patient and research use. A handheld detector optically excites the pressure-sensitive nanophotonic structure of the IOP-sensing implant placed in the anterior chamber and detects the reflected light, whose optical signature changes as a function of IOP. Optical detection eliminates the need for large, complex LC structures and simplifies sensor design. The use of nanophotonic components improves the sensor's resolution and sensitivity, increases optical readout distance, and reduces its size by a factor of 10-30 over previous implants. Its small size and convenient optical readout allows frequent and accurate self-tracking of IOP by patients in home settings. | 01-21-2016 |
