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.
Claims94
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 pressure probe at a controlled constant fluid flow rate, in which the pneumatic fluid supply comprises:
- a pump having an output adapted to provide a pressurized flow of pneumatic fluid to the pressure probe for applying force to the surface of the eye;
- and
- a pressure compensated fluid flow rate regulator having an input and an output, the input of the pressure compensated fluid flow rate regulator connected to the output of the pump and the output of the pressure compensated fluid flow rate regulator connected to the probe, the pressure compensated fluid flow rate regulator adapted to provide a controlled constant fluid flow rate from its output to the probe regardless of pressure fluctuations.
