Device for the measurement of electrical potentials of the eye
First Claim
1. A device for the measurement of electrical potentials appearing on the cornea of the human or aninal eye in response to a light stimulation of said eye and so as to establish an electroretinogram (ERG), which consists in a corneal lens provided with a measurement electrode, at least a portion of said electrode being flush with the concave surface of the lens or protruding from said surface so as to be in service position directly in contact with the cornea of the eye, and the convex surface of the lens comprising means for maintaining in service position the eyelids opened.
