ABSTRACT:
A transducer, placed on an eye being tested, generates an analog signal representative of pressure. The analog signal is periodically converted to digital signals in binary coded decimal representation. Each test is carried out under control of a computer driven by a real time clock which is actuated in response to placing the tonometer in test position on an eye. The computer takes the tonometer measurements at predetermined times as determined by the real time clock, and stores the data in a random access memory, together with signals representative of other important test parameters. From this data, the computer calculates intraocular pressure, the coefficient of outflow value and the flow value, which are also stored in the memory. A visual display unit is associated with the memory for displaying the tonometer measurement data, test parameters and computed results. Test measurements and other test parameters may also be loaded into the system by a manually operated keyboard for computation and display. The computation takes into account many of the artifacts which previously has decreased accuracy. A pair of signal lights on the handpiece are energized by control logic for indicating to the clinician the exact status of the test whether the results being obtained are satisfactory, and whether current or old test data is stored in the memory, without having to divert his attention from the handpiece placed on the eye.
