ABSTRACT:
A method and apparatus for adjusting a visual image provided to a patient. In one embodiment, an image may be presented to the patient to obtain the patient's subjective perception of the image, and the patient may either manipulate the image to obtain a desired adjustment, or guide a clinician performing the adjustment. In another embodiment, the clinician may make objective observations of, for example, the position of an electrode array on the patient's retina, and make adjustments accordingly. The adjustment may be a spatial adjustment comprising a re-mapping performed to decreases image distortion resulting from differences in the patient's perception of stimulation of different areas of the retina. Such distortion may result from differences between the patient's perception of stimulation falling within the macula, and stimulation falling within the periphery surrounding the macula. The adjustment may also compensate for translations or rotations of the electrode array on the retina.
