Through a combination of gene therapy, eyeglass cameras, and visual cortex implantation, partial restoration of vision in those suffering from disorders such as age-related macular degeneration (AMD) may become a reality.
Researchers are attempting to bypass the damaged retina and create new photo-receptors in the visual cortex (through gene therapy). These new photo-receptors would receive stimulation through an implant powered by induction coils, similar to those found in cochlear implants.
The visual cortex implant receives its information through a pair of glasses equipped with cameras tracking eye position and what is in the person’s line of site. These glass would be similar to the body or ear-level processors of modern cochlear implants.
While clinical application is still a few years away, the future of vision implants is certainly bright.

What is listening fatigue? Fatigue in general refers to a “weariness” resulting from exertion. In many children who are Deaf and/or hard of hearing (D/HH), listening fatigue occurs due to their need for increased concentration and attention. In many situations, children who are D/HH often have to work harder and pay closer attention than their…
The impact of sound exposure in humans has been the subject of thousands of research studies. Of course, animal models have been used in these studies primarily to infer how exposure might affect the human auditory system. Far fewer studies have looked at how noise affects the other members of the animal kingdom. Increased interest in…
David Friedmann, MD, has a Veterans Affairs (VA) Health Service Research and Development (HSR&D) grant (PPO 19-397) ending this month that may be of interest to audiologists. Dr. Friedmann is a neurotologist and skull-base surgeon at the Manhattan New York Harbor VA Medical Center and an associate professor in the Department of Otolaryngology-Head and Neck…
