What do blind people “see” with retinal prostheses? Observations and qualitative reports of epiretinal implant users

open access: yesbioRxiv, 2020
Introduction: Retinal implants have now been approved and commercially available for certain clinical populations for over 5 years, with hundreds of individuals implanted, scores of them closely followed in research trials. Despite these numbers, however,

Global activity shaping strategies for a retinal implant

open access: yesJournal of Neural Engineering, 2019
Objective. Retinal prostheses provide visual perception via electrical stimulation of the retina using an implanted array of electrodes. The retinal activation resulting from each electrode is not point-like; instead each electrode introduces a spread of

History of Retinal Implants

open access: yesTexas Journal of Medical Science, 2023
Vision is the ability to perceive light stimuli through the eyes, transport information to the brain, which subsequently interprets it in order to relate to the world around us. In this way we can correctly distinguish between colors, shapes, movements and distances.
