Figure Legend:
Prototype suprachoroidal retinal prosthesis. (A) The device consisted of a percutaneous connector connected via a cable to an electrode array designed to be implanted in the suprachoroidal space of the eye. (B) Schematic illustration of the electrode array (not to scale). Twenty stimulating electrodes (17 × 600-μm and 3 × 400-μm diameter) are arranged in a hexagonal grid, surrounded by 13 interconnected 600-μm-diameter electrodes that form a guard-ring return. Two large return electrodes (2-mm diameter) are also included in the array. (C) Fundus image recorded from P1. The electrode array implanted in the suprachoroidal space is visible through the retina and choroid. (D) The percutaneous connector is implanted behind the ear, providing a direct electrical connection to the implanted electrodes. Image in (A) courtesy of D.A.X. Nayagam.
