Implants with photosensitive pixels, such as that from Retina Implant AG, largely overcome the scalability limitation and make use of natural eye movements, but still require external power delivered via RF coils and a trans-scleral cable.Ī fully optical design overcomes these limitations by using subretinal stimulating arrays of photodiodes powered by pulsed near infrared (NIR, 880–915nm) illumination. Furthermore, retinal stimulation in this system is directly determined by images captured by the external camera, disregarding the use of natural eye movements to scan a visual scene, a crucial feature of normal visual perception. The bulky receiving coil and processing electronics of the implant make the surgery very difficult, and together with the penetrating intraocular cable make it prone to multiple surgical complications. Such a design is difficult to scale to a much larger number of electrodes than the 60 in the current model. ![]() Recently approved by the FDA, the ARGUS II implant (Second Sight Inc.) delivers information from an external camera and an external signal processing unit via serial RF telemetry to a sub-conjunctival receiving coil connected to a signal processing module, which then relays the stimulation signals to the epiretinal electrode array via a trans-scleral cable. However, both of these systems suffer from a number of shortcomings. Recent clinical studies with epiretinal and subretinal prosthetic systems have demonstrated improvements of the visual function in certain tasks, with some patients being able to identify letters with equivalent visual acuity of up to 20/550. Electrical stimulation of the surviving retinal neurons has been achieved either epiretinally, in which case the primary targets of stimulation are the retinal ganglion cells (RGCs), or subretinally to bypass the degenerated photoreceptors and use neurons in the inner nuclear layer (bipolar, amacrine and horizontal cells) as primary targets. Activation of the remaining neurons can produce visual percepts, known as phosphenes, thereby enabling delivery of information to the visual system in a blind patient. These diseases lead to a loss of photoreceptors, while the inner retinal neurons survive to a large extent. You’re sure to attract the attention of audiences of all ages with the breakthrough technology of the HOLOCIRCLE 65X.Retinal degenerative diseases such as age-related macular degeneration or retinitis pigmentosa are among the leading causes of blindness in the developed world.
