METHOD AND SYSTEM FOR EYE TREATMENT

Methods and systems including a first electrode substrate having one or more stimulation electrodes that are configured to apply electrical stimulation signals to a patient's first eye; a plurality of sensor electrodes configured to detect electrical activity from neural cells of the patient during delivery of an electrical-stimulation therapy, wherein the plurality of sensor electrodes includes a first sensor electrode and a second sensor electrode; a first return electrode configured to be placed in a location on the patient such that an electrical current is formed between at least one of the one or more stimulation electrodes and the first return electrode; and a stimulation controller configured to control the electrical current formed between the at least one of the one or more stimulation electrodes and the first return electrode such that the electrical current passes through a retina of the patient's first eye and delivers the electrical-stimulation therapy.
