In this review, we present a summary of behavioral tests employed for assessing visual function and functional vision, including traditional techniques as well as innovative approaches incorporating virtual reality (vr) environments and eye tracking methodologies.
Retinal Physician Pentavision The objective of this feasibility study is to evaluate the safety and utility of the argus ii retinal stimulation system in providing visual function to blind subjects with retinitis pigmentosa. In this review, we present a summary of behavioral tests employed for assessing visual function and functional vision, including traditional techniques as well as innovative approaches incorporating vr environments and eye tracking methodologies.
