Abstract:
1. An electrode array for electroretinography comprising: a contact lens body having an outer periphery, an inner surface facing a patient's eye and an opposing outer surface; an array of a plurality of conductive members carried on the inner surface of the contact lens body so as to be integral therewith; multiple groups of linear conductive members being positioned about the contact lens body with different groups pointing in different directions so that at least a portion of the conductive members contacts the patient's cornea; the array of conductive members being spaced apart from one another so as to be substantially transparent to full-field stimulation of the patient's eye; the conductive members extending to the outer periphery of the contact lens body; and connections for electrically connecting the conductive members to electrical circuitry external to the electrode for monitoring the array of conductive members at multiple locations, simultaneously, for the distribution of electrical activity of the retina as recorded at multiple locations across the cornea in response to the full-field stimulation, each connection being provided at the outer periphery so as to be integral with the contact lens body.
