Pixium Vision Retinal Chip Shows Sustained Success

"Pixium Vision announced sustained success of its PRIMA System after 12-months in dry age-related macular degeneration patients." July 18, 2019

Advanced Dry Macular Degeneration

The Bionic Vision Restoration System, by Pixium Vision received approval in the fall of 2017 from French regulators for the implant of a retinal chip in patients who have advanced dry macular degeneration (AMD).

The chip is 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 five patients received the retinal implant and activation of the PRIMA system in France in 2018 followed by visual rehabilitation. The participants have advanced atrophic (dry) macular degeneration. According to Pixium, "None of the patients had remaining central visual activity at enrollment."

Symptoms of Advanced Dry 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. Lloyd Diamond, Chief Executive Officer stated: “We are pleased to have confirmed the durability of the better than expected outcome in our 6-month interim results in this 12-month data set.

The fact that patients were able to not only re-establish light perception but also identify letters suggests that the PRIMA System may soon afford patients life changing improvements in quality of life."
