Psychophysical Evaluation for Visual Prosthesis
Annual Review of Biomedical Engineering, 2008Vision restoration through retinal, optic nerve, and cortical implants is no longer just the stuff of fantasy. The design and development of visual prostheses rapidly move from the engineering phase toward preclinical and clinical trials, yet the benchmarks to determine their efficacy in blind research subjects have received very little attention, and

An Efficient Microcontroller for Visual Cortical Prosthesis
2021 3rd Novel Intelligent and Leading Emerging Sciences Conference (NILES), 2021Medical implant devices (MID) are becoming increasingly used as a means of treating human disorders. Among such MIDs, the visual cortical prosthesis (VCP) is one of the treatments for blind people who want to restore their vision. The visual cortex stimulator (VCS) is a device that requires a reliable power source as well as quick data transfer ...

Simulated phosphene model for visual prosthesis
2012 5th International Conference on BioMedical Engineering and Informatics, 2012Two simulated phosphene models were proposed in this paper. Model I was based on uniform or Gaussian round or square spots which arranged in rectangle or hexagonal arrays. Model II was based on partial clinical experiment data of one optic nerve prosthesis research. Numbers, letters and Chinese characters were pixelated by these models. The feasibility

Stability of a Suprachoroidal Visual Prosthesis
2014Background: In 2012, Bionic Vision Australia implanted three patients with end-stage retinitis pigmentosa with a prototype suprachoroidal visual prosthesis implant. The suprachoroidal implant location was chosen, in part, for the hypothesised improved device stability. This paper will detail the initial[for full text, please go to the a.m. URL]

[Review of visual prosthesis (I)--retinal prosthesis].
Sheng wu yi xue gong cheng xue za zhi = Journal of biomedical engineering = Shengwu yixue gongchengxue zazhi, 2009Research on how to totally or partially restore the vision has attracted more attention in the fields of neural engineering and tissue engineering. Neural interface and visual prosthesis offer alternative ways for partially repairing the visual impairment. The most widely used visual prosthetics are based on retinal stimulation. This article is a state-

Electrophysiology Techniques in Visual Prosthesis
2018Research in the field of visual prosthesis is advancing quickly with several groups around the world joining efforts to produce more effective and safe implants. In particular, new stimulation strategies are being investigated to elicit more meaningful percepts of light and to safely increase the visual acuity achieved by these devices.
