Australian researchers are undertaking world-class research towards
the development of bionic visual prostheses. Teams based at Monash
University and the University of Melbourne are developing
direct-to-brain and retinal-based devices respectively, that elicit the
perception of small spots of light called phosphenes. These phosphenes
will then be assembled to produce a basic form of imagery akin to early
computer games, albeit with the advantage of modern computer processing
power to ensure they display only the most relevant details about the
user's environment.
In this paper the authors review
the latest advances in retinal and visual cortex stimulation and
discusse the surgical and functional outcomes reported to date for
retinal and cortical prostheses. They conclude with a brief discussion of
advances in the field and an outlook for the future.
