Photovoltaic Restoration of Central Vision in Atrophic Age-Related Macular Degeneration

Publication Loss of photoreceptors in atrophic age-related macular degeneration results in severe visual


Implantation of the PRIMA did not decrease the residual natural acuity, and it restored visual sensitivity in the former scotoma in each of the 5 patients. In 3 patients with the proper placement of the chip, prosthetic visual acuity was only 10% to 30% less than the level expected from the pixel pitch (20/420). Therefore, the use of optical or electronic magnification in the glasses as well as smaller pixels in future implants may improve visual acuity even further.
