Journal ArticleDOI

Mark S. Humayun,James D. Weiland,Gildo Y. Fujii,Robert J. Greenberg,Richard Williamson,James Singleton Little,Brian V. Mech,Valerie Cimmarusti,Gretchen B. Van Boemel,Gislin Dagnelie,Eugene de Juan +10 more
TL;DR: A retinal prosthesis was permanently implanted in the eye of a completely blind test subject and the subject was able to see perceptions of light (spots) on all 16 electrodes of the array.
Journal ArticleDOI
A new 25-gauge instrument system for transconjunctival sutureless vitrectomy surgery.
Gildo Y. Fujii,Eugene de Juan,Mark S. Humayun,Dante J. Pieramici,Tom S. Chang,Eugene Ng,Aaron Barnes,Sue Lynn Wu,Drew N. Sommerville +8 more
TL;DR: The 25-gauge transconjunctival sutureless vitrectomy system (TSV) was evaluated in vitro using balanced saline solution and porcine vitreous for several levels of aspiration power and bottle height.
Journal ArticleDOI
Pattern electrical stimulation of the human retina
Mark S. Humayun,Eugene de Juan,James D. Weiland,Gislin Dagnelie,Steve Katona,Robert J. Greenberg,Satoshi Suzuki +6 more
TL;DR: Experiments were conducted to study if electrical stimulation of the retinal surface can elicit visual sensation in individuals blind from end-stage retinitis pigmentosa (RP) or age-related macular degeneration (AMD).
Journal ArticleDOI
Preservation of the Inner Retina in Retinitis Pigmentosa: A Morphometric Analysis
Arturo Santos,Mark S. Humayun,E. de Juan,R. J. Greenburg,Marta J. Marsh,Ingrid B. Klock,Ann H. Milam +6 more
TL;DR: In this paper, the extent of preservation in the inner retina in retinitis pigmentosa (RP) was determined by counting cell nuclei in the outer nuclear, inner nuclear, and ganglion cell layers within thirty 100-μm intervals from the foveola to 1500μm eccentricity.
Journal ArticleDOI
Interim Results from the International Trial of Second Sight's Visual Prosthesis
Mark S. Humayun,Jessy D. Dorn,Lyndon da Cruz,Gislin Dagnelie,José-Alain Sahel,Paulo E. Stanga,Artur V. Cideciyan,Jacque L. Duncan,Dean Eliott,Eugene Filley,Allen C. Ho,Arturo Santos,Avinoam B. Safran,Aries Arditi,Lucian V. Del Priore,Lucian V. Del Priore,Robert J. Greenberg +16 more
TL;DR: The long-term safety results of Second Sight's retinal prosthesis system are acceptable, and most subjects with profound visual loss perform better on visual tasks with system than without it.
