Abstract
A system and method analyzes tonosignals and other electrical signals such as those representative of force-displacement information from applanating probes initially to determine the presence of an acceptable waveform or tonosignal. Once an acceptable waveform is found, that waveform is analyzed further to locate the point of applanation. The level of the waveform at that point may be converted to a digital signal and displayed to indicate the pressure within the eye or other objects to which the probe is applied.
