Abstract
An integrated device for improving the visual system of a human subject includes a computer having a timer and in data communication with a display, a current source and a housing that contains the current source in addition to at least one of the display and the computer. The computer and display are adapted to present optical stimuli to a targeted region of an eye. The current source has at least one terminal for connection of at least one electrode assembly. The timer measures a time relationship. The current source provides electrical stimulation to the subject's brain and the display provides optical stimulation to the subject's eye in a time relationship determined by the timer
Claims28
An integrated device for improving the visual system of a human subject having an eye, a head, and a skull the device comprising:
- a computer in data communication with a display, the computer and display adapted to present optical stimuli to a targeted region of an eye, the computer including a timer for measuring a time relationship;
- a current source having at least one connector for connection of at least one electrode assembly;
- and
- a housing adapted to contain the current source in combination with at least one of the display and the computer,
- wherein the current source provides electrical stimulation to the subject's brain and the display provides optical stimulation to the subject's visual system in the time relationship.
A method for visual therapy comprising:
- applying an first orbital electrode around the eye of a patient;
- applying a second electrode to the patient, the orbital electrode and second electrode defining a current path through a target structure of the visual system of the patient;
- identifying a desired zone for optical stimulation based on a visual field map of the patient;
- presenting an optical stimulus to the zone;
- measuring a response of the patient to the optical stimuli;
- and
- administering a galvanic current to the target structure via the current path, wherein the administering a galvanic current is synchronized with the optical stimulus.
A method for visual therapy comprising:
- applying a cathodic electrode and an anodic electrode to the patient, the cathodic electrode and anodic electrode defining a current path through a target structure of the visual system of the patient, wherein the anodic electrode is applied to be external and in contact with the skin of a patient;
- identifying a desired zone for optical stimulation based on a visual field map of the patient;
- presenting an optical stimulus to the zone;
- measuring a response of the patient to the optical stimuli;
- and
- administering a galvanic current to the target visual structure via the current path, wherein the administering a galvanic current is synchronized with the optical stimulus.
