Abstract
Apparatus for the assessment of electrophysiological signals obtained from a patient, the apparatus comprising: a housing; a support arch pivotally mounted to the housing, the support arch comprising a plurality of facial contact point supports for supporting contact points on the face of the patient relative to the support arch without supporting the chin of the patient; at least one display screen for presenting a stimulus to a single eye of the patient, the at least one display screen being movable relative to the support arch; and control electronics disposed within the housing for driving the at least one display screen and for amplifying electrophysiological signals obtained from the patient.
Claims24
An apparatus for an assessment of electrophysiological signals obtained from a patient, the apparatus comprising:
- a support for supporting a head of the patient;
- a first electrode configured to be mounted to a first eye of the patient, and a second electrode configured to be mounted to a second eye of the patient;
- a ground electrode configured to be mounted to the patient;
- a first display screen disposed before the first eye of the patient for selectively presenting a visual stimulus to the first eye of the patient, and a second display screen disposed before the second eye of the patient for selectively presenting a visual stimulus to the second eye of the patient, the first display screen and the second display screen being movable relative to the support, and the first display screen and the second display screen being configured such that none of the visual stimulus presented to the first eye of the patient by the first display screen is perceived by the second eye of the patient, and none of the visual stimulus presented to the second eye of the patient by the second display screen is perceived by the first eye of the patient;
- and
- control electronics for selectively driving the first display screen and the second display screen, and for amplifying electrophysiological signals obtained from the first electrode and the second electrode;
- wherein the control electronics are configured to (i) drive the first display screen so as to present a visual stimulus to the first eye of the patient while not driving the second display screen, or to (ii) drive the second display screen so as to present a visual stimulus to the second eye of the patient while not driving the first display screen;
- and
- wherein the control electronics are configured to (i) use the first electrode as an active electrode and to use the second electrode as a reference electrode when the first eye is stimulated by the first display screen, and (ii) use the second electrode as an active electrode and to use the first electrode as a reference electrode when the second eye is stimulated by the second display screen.

A method for an assessment of electrophysiological signals obtained from a patient, the method comprising:
- providing an apparatus comprising:
- a support for supporting a head of the patient;
- a first electrode configured to be mounted to a first eye of the patient, and a second electrode configured to be mounted to a second eye of the patient;
- a ground electrode configured to be mounted to a body of the patient;
- a first display screen disposed before the first eye of the patient for selectively presenting a visual stimulus to the first eye of the patient, and a second display screen disposed before the second eye of the patient for selectively presenting a visual stimulus to the second eye of the patient, the first display screen and the second display screen being movable relative to the support, and the first display screen and the second display screen being configured such that none of the visual stimulus presented to the first eye of the patient by the first display screen is perceived by the second eye of the patient, and none of the visual stimulus presented to the second eye of the patient by the second display screen is perceived by the first eye of the patient;
- and
- control electronics for selectively driving the first display screen and the second display screen, and for amplifying electrophysiological signals obtained from the first electrode and the second electrode;
- wherein the control electronics are configured to (i) drive the first display screen so as to present a visual stimulus to the first eye of the patient while not driving the second display screen, or to (ii) drive the second display screen so as to present a visual stimulus to the second eye of the patient while not driving the first display screen;
- and
- wherein the control electronics are configured to (i) use the first electrode as an active electrode and to use the second electrode as a reference electrode when the first eye is stimulated by the first display screen, and (ii) use the second electrode as an active electrode and to use the first electrode as a reference electrode when the second eye is stimulated by the second display screen;
- adjusting the support so as to properly support the head of the patient, and adjusting the first display screen and the second display screen relative to the support;
- mounting the first electrode to the first eye of the patient, mounting the second electrode to the second eye of the patient, and mounting the ground electrode to the body of the patient;
- and
- providing a visual stimulus to one of the first eye of the patient or the second an eye of the patient with the first display screen or the second display screen, respectively, such that (i) if the first eye of the patient is stimulated by the first display screen, an electrophysiological signal is obtained by using the first electrode as the active electrode and the second electrode as the reference electrode, and (ii) if the second eye of the patient is stimulated by the second display screen, an electrophysiological signal is obtained by using the second electrode as the active electrode and the first electrode as the reference electrode.
