Testing of Semichronically Implanted Retinal Prosthesis by Suprachoroidal-Transretinal Stimulation in Patients with Retinitis Pigmentosa

Abstract: Semichronic implantation of a microelectrode-STS system showed that it was safe and remained functional for at least 4 weeks in two patients with advanced RP. (www.umin.ac.jp/ctr number, R000002690.).

“…In the first, an external device (such as a small camera) captures the light and a microprocessor is used to convert the light to electrical signals. [23][24][25][26] A second approach incorporates a photodiode array with the stimulating electrodes on the same device. 13,[27][28][29] The electrode array is positioned either on the surface of the retina (epiretinal) to interface with the retinal ganglion cells (RGCs), or under the retina (subretinal) to substitute for the degenerated photoreceptors and to stimulate the inner retinal neurons (mostly bipolar, but possibly also amacrine and horizontal cells).…”

“…Düzenli fosfen oluşumu için lokalize uyartım ile yalnızca uyartım yapılan elektrot etrafında alan oluşturmak gerekir [27]. Bu sayede, hedeflenen noktanın çok uzağında olan, 16 piksel, uzaysal çözünürlüğün de artırılması mümkün olur.…”

“…6(a), where each electrode is directly connected by a lead wire. Figure 7 shows an implant system of a retinal prosthesis where only nine electrodes are directly connected to the main unit with flexible lead [9]. In this type, when the number of electrodes is increased, the flexible lead is too thick and rigid to implant.…”
