Visual prosthesis fitting

1. A computer-operated system for visual stimulation comprising a display component, the display component having a graphical user interface configured to display a visual representation of an image to a visual field of a patient, and wherein the graphical user interface is suitable for providing user feedback and suitable for supporting a method for fitting a visual prosthesis having a plurality of electrodes the graphical user interface comprising:

a first screen including means for selecting electrodes for visual stimulation, wherein selected electrodes for the visual stimulation create the visual representation displayed to the visual field of the patient; and

a second screen including a plurality of representations of threshold values within the visual representation of the visual field of the patient;

wherein the visual representation is displayed to the visual field of the patient and the plurality of electrodes are suitable to elicit perception of light.

2. The system of claim 1 , wherein the first screen comprises an electrode window for selecting one or more electrodes to be activated.

3. The system of claim 1 , wherein the first screen comprises a stimulation screen.

4. The system of claim 1 , wherein the second screen provides one or more buttons that indicate which electrodes of the plurality of electrodes are activated.

5. A graphical user interface, the graphical user interface adapted to be displayed on a display component and used with a computer-operated system, the computer-operated system adapted for visual stimulation of a visual prosthesis having a plurality of electrodes, the graphical user interface configured to display a visual representation of an image to a visual field of a patient, the graphical user interface comprising:

a first screen, wherein the first screen comprises a plurality of stimulation selection buttons for visual stimulation, configured for selecting an electrode by pressing one of said plurality of stimulation selection buttons corresponding to the selected electrode;

a second screen including a plurality of representations of threshold values within the visual representation of the visual field of the patient;

wherein:

the visual representation is configured to be displayed to the visual field of the patient and is created by selecting the plurality of stimulation selection buttons based on the image, and

the plurality of electrodes are suitable to elicit perception of light.

6. The graphical user interface of claim 5 , wherein the first screen is further configured to display a plurality of windows, and wherein the plurality of windows are configured for assigning values to stimulation parameters.

7. The graphical user interface of claim 6 , wherein the stimulation parameters are at least one of stimulation amplitude of a particular electrode from the plurality of electrodes, time between successive stimulations by the particular electrode, and time differences between stimulations by one electrode in the plurality of electrodes and stimulation by another electrode in the plurality of electrodes.

8. The graphical user interface of claim 5 , wherein the second screen is further configured to display a plurality of windows, and wherein the plurality of windows are configured for configuration of a pre-set experiment on the patient by use of the visual prosthesis.

9. The graphical user interface of claim 8 , wherein the pre-set experiment is based on selection of at least one of: duration of time of an experiment, one or more electrodes from the plurality of electrodes to stimulate in the experiment, stimulation amplitude of the one or more electrodes at any given moment in time in the duration of time, and number of times to stimulate the one or more electrodes.
