Performance of real-world functional vision tasks by blind subjects improves after implantation with the Argus® II retinal prosthesis system.

ABSTRACT:

Background

The main objective of this study was to test Argus II subjects on three real-world functional vision tasks.

Design

The study was designed to be randomized and prospective. Testing was conducted in a hospital/research laboratory setting at the various participating centres.

Participants

Twenty eight Argus II subjects, all profoundly blind, participated in this study.

Methods

Subjects were tested on the three real-world functional vision tasks: Sock Sorting, Sidewalk Tracking and Walking Direction Discrimination task MAIN OUTCOME MEASURES: For the Sock Sorting task, percentage correct was computed based on how accurately subjects sorted the piles on a cloth-covered table and on a bare table. In the Sidewalk Tracking task, an 'out of bounds' count was r
