FIG. 11.6 Subretinal prostheses. (a) The Alpha-IMS subretinal prosthesis. Adapted from Zrenner et al., Proc. Biol. Sci. 278 , 1489–1497 (2011). Copyright 2011 Author(s), licensed under the Creative Commons Attribution License (CC BY). (b) System diagram showing the photovoltaic retinal prosthesis, including the camera integrated into augmented reality-like video glasses, with the processed image projected onto the retina using pulsed near-infrared light. The subretinal photovoltaic array converts pulsed light into pulsed electric current in each pixel to stimulate the adjacent inner retinal neurons. Each pixel includes two diodes (1 and 2), connected in series between the active (3) and return (4) electrodes (scale bar is 50 µm). (c) Fundus image (top) and optical coherence tomography image (bottom) of the subretinal implant placed below the macula of one patient with atrophic AMD. Panels (b) and (c) are adapted from Palanker et al., Ophthalmology 127 , 1097–1104 (2020). Copyright 2020 Author(s), licensed under the Creative Commons Attribution License (CC BY).
