Abstract:
1. A method of monitoring optic function comprising: providing at least one sensor and at least one visual evoked potential stimulator; disposing the at least one sensor and at least one visual evoked potential stimulator in stimulating relation with at least one eye of a patient, and the at least one sensor in monitoring relation with the patient; activating the stimulator to stimulate at least two portions of the at least one eye selected from the group consisting of the optic nerve, optic chiasma and the optic cortex to produce signals, said signals forming a visual evoked potential, the visual evoked potential being characterized by a waveform; collecting the waveform of the visual evoked potential in the at least one sensor; providing a data processor in signal communication with the at least one sensor to collect the waveform from the at least one sensor; and processing the measured waveform in the data processor such that changes in the waveform of the visual evoked potential over time are monitored for an adverse change in optic function to provide a real-time gauge of the health of the optic nerve of the patient, wherein the processing includes an analysis of at least the temporal interval (TL1) between the onset of stimulation (t
