Abstract
A composite ocular blood flow analyzer uses pneumatic tonometric techniques and structures to produce accurate, stable, and repeatable readings of intraocular pressure. A computer processes the intraocular pressure readings to produce data relating to various aspects of ocular blood flow that can be used diagnostically to identify abnormalities in the eye and other parts of the body.
Claims119
A composite ocular blood flow analyzer, comprising:
- a pressure probe adapted to be placed in contact with a human eye;
- and
- a pneumatic fluid supply adapted to supply pneumatic fluid to the probe at a controlled substantially constant flow rate.
A method of measuring composite ocular blood flow, comprising the steps of:
- applying force to an eye with a pressure probe supplied with fluid from a pressure compensated flow regulated pump driven by a brushless DC electric motor;
- and
- detecting pressure fluctuations in the probe in response to contact of the probe with an eye.
