Claims17
A conductive electrode assembly for the measurement of corneal electroretinographic (ERG) signals, the electrode assembly comprising:
- a bead shaped electrode adapted to contact a subject's eye;
- and
- a flexible wire supporting the bead shaped electrode, wherein the wire is configured to be mounted to enable the bead shaped electrode to make contact with a junction between a cornea and sclera of the subject's eye.
An electrode assembly for measuring electroretinographic (ERG) signals from a subject's eye, the electrode assembly comprising:
- an electrode adapted to contact a subject's eye;
- and
- a wire supporting the electrode between first and second ends of the wire, wherein the first and second ends of the wire are configured to be mounted to enable the electrode to make contact with a junction between a cornea and sclera of the subject's eye.
A method of applying an electrode to a patient's eye, the method comprising:
- providing an electrode assembly for contacting a subject's eye, the electrode assembly including an electrode and a wire supporting the electrode between first and second ends of the wire;
- and
- mounting the electrode assembly to enable the electrode to make contact with a junction between a cornea and sclera of the subject's eye.
