Performance of Real-world Functional Tasks Using an Updated Oral Electronic Vision Device in Persons Blinded by Trauma.

Unlabelled: There is an immediate need for noninvasive therapies to improve the functional abilities of persons blinded by traumatic injury. The BrainPort Vision Pro, an updated hands-free oral electronic vision device, enables perception of visual information using the tongue as a substitute for the eye.

Purpose: The purpose of this study was to evaluate the impact of the BrainPort Vision Pro on real-world functional task performance in persons who are profoundly blind (light perception or worse) due to traumatic injury (ocular or cortical).
