Abstract
A device for electrically exciting tissue in the uveal and periuveal areas of the eye includes a frame similar to an eyeglass frame in shape and construction. Two flat, disk-shaped electrodes are attached to the frame. When the frame is placed on the head of the patient, the electrodes are positioned adjacent the orbits of the patient's eyes. A voltage source and electronic circuitry is provided to establish a voltage differential between the electrodes thereby allowing electrical currents to flow from one electrode to the other, stimulating the tissue and other cells in the uveal and periuveal areas of the eyes. Alternatively, the patient's body can be isolated from ground and the voltage source used to place a negative charge on each electrode to thereby create beneficial negative ions in the uveal and periuveal areas of each eye.
