Journal ArticleDOI
Retinal Prosthesis for the Blind
Eyal Margalit,Mauricio Maia,James D. Weiland,Robert J. Greenberg,Gildo Y. Fujii,Gustavo Torres,Duke V. Piyathaisere,Thomas M. O’Hearn,Wentai Liu,Gianluca Lazzi,Gislin Dagnelie,Dean A. Scribner,Eugene de Juan,Mark S. Humayun +13 more
TL;DR: Cortical prostheses will be described only because of their direct effect on the concept and technical development of the other prostheses, and this will be done in a more general and historic perspective.
Journal ArticleDOI
Visually Guided Performance of Simple Tasks Using Simulated Prosthetic Vision
Jasmine S. Hayes,Vivian T. Yin,Duke V. Piyathaisere,James D. Weiland,Mark S. Humayun,Gislin Dagnelie +5 more
TL;DR: To simulate the vision levels that recipients of retinal prostheses with 4 x 4, 6 x 10, and 16 x 16 electrode arrays may experience, and to test the functionality of this vision, a set of tasks including four-choice orientation discrimination of a Sloan letter E was designed.
Journal ArticleDOI
Visual and electrical evoked response recorded from subdural electrodes implanted above the visual cortex in normal dogs under two methods of anesthesia.
Eyal Margalit,James D. Weiland,R.E Clatterbuck,Gildo Y. Fujii,Mauricio Maia,M. Tameesh,Gustavo Torres,Salvatore A. D'Anna,S Desai,Duke V. Piyathaisere,A Olivi,E. de Juan,Mark S. Humayun +12 more
TL;DR: Subdural electrodes show promising results for recording visual and electrical evoked responses (EERs) and thus for evaluation of the retinal prosthesis in dogs under two methods of anesthesia-halothane and propofol.
Journal ArticleDOI
Comparison of electrical stimulation thresholds in normal and retinal degenerated mouse retina.
Satoshi Suzuki,Mark S. Humayun,James D. Weiland,Shih Jen Chen,Eyal Margalit,Duke V. Piyathaisere,Eugene de Juan +6 more
TL;DR: The amount of electrical charge required to elicit an action potential is dependent on the condition of the retina and the shape of the stimulus pulse used to deliver the charge.
Journal ArticleDOI
Bioadhesives for intraocular use.
Eyal Margalit,Gildo Y. Fujii,James C. Lai,Puneet Gupta,Shih Jen Chen,Jeng-Shyong Shyu,Duke V. Piyathaisere,James D. Weiland,Eugene deJuan,Mark S. Humayun +9 more
TL;DR: A safe, effective adhesive could be useful in the management of retinal holes or tears and selected complicated retinal detachments, as well as for attaching a small electronic device (retinal prosthesis) to the retina.
