A New Retinal Chip for Improved Central Vision Update

The Bionic Vision Restoration System, by Pixium Vision received approval this fall from French regulators for the implant of a retinal chip in patients who have advanced dry macular degeneration (AMD).

The chip will be surgically placed in the subretinal space and works in conjunction with a headworn camera and a small data transmitter. Artificial stimulation of degenerated photoreceptor cells allows for better communication between the eye and the brain.

Clinical Trial Update

The first patient received the Pixium retinal implant and activation of the PRIMA system in France in January of 2018. The patient had advanced atrophic (dry) AMD with severe vision loss. According to Pixium Vision's press release, "The PRIMA Bionic Vision System successfully elicited visual perception. This enables the patient to start the re-education phase as per the trial protocol, which includes a 6-month follow-up and progress update." A second study sight in the U.S. will begin recruiting 5 patients who also have advanced dry AMD.

Symptoms of Advanced AMD

Symptoms of advanced dry macular degeneration include a blurred, cloudy or gray area right in the center of one's vision making it difficult to read or recognize faces.

Using a higher 378 electrode chip, the PRIMA (Photovoltaic Retinal Implant) hopes to improve a patient's central vision. “What people [with AMD] ideally want is to read again and to recognize faces,” says Khalid Ishaque, CEO of Pixium.
