    摘要: Applicant has proposed a combination of the subretinal and epiretinal methods by placing the electronics external to the eye, entering the eye through the pars plana and the piercing the retina (retinotomy) from inside the eye to stimulate subreintally.The present invention is an improved electrode array for subretinal stimulation. A hard polymer such as polyimide is biocompatible and strong for supporting an electrode array and supporting traces in a thin flex circuit array. In the present invention applicant takes advantage of the sharp nature of thin polyimide making a point on the end of the electrode array. This allows the flexible circuit electrode array to be both electrode array and surgical tool to cut the retinal and slide the array under the retina in a single action.

    摘要: 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.

    摘要: A method and apparatus for improving visual acuity when providing a visual image from a “high” resolution input device to a “low” resolution output device. The described invention is of particular use when the output device is an array of electrodes as part of a retinal prosthesis used to restore vision to a visually-impaired patient. In that various limitations may, within the foreseeable future, limit the density of such an electrode array (and thus the resolution of the output image), the present invention teaches techniques to assign processed pixel subsets of a higher resolution image to a single electrode. By varying the pixel subsets, e.g., by jittering, and/or altering the processing criteria, the perceived visual acuity may be further improved. Alternatively and additionally, such processing may be further extended to drive neighboring electrodes in combination to thus stimulate virtual electrode sites and thus further enhance visual acuity.
