“…The most basic parameter for a retinal implant is the threshold charge at which a visual percept is elicited, and this will vary across electrodes and patients (de Balthasar et al, 2008;Ahuja et al, 2013;Shivdasani et al, 2014). Not all electrodes will produce a percept; large electrode-retina distances or smaller ganglion cell densities adjacent to the electrode are both factors that will increase the activation threshold (Ahuja et al, 2013) and may require electrodes to be stimulated as groups of two or more before a threshold is obtained (Tran and Wolfensberger, 2017).…”

“…1,2 Literatürde plateletten zengin plazma tedavisi (PRP), kök hücre tedavisi, retinal implantlar ve gen tedavisi gibi değişik çalışmalar mevcut olmasına ragmen henüz etkili ve kesin bir tedavisi yoktur. [3][4][5][6][7] Retinitis pigmentozalı olgularda görme keskinliğinin azalması ve progresif görme alanı kaybı olmasından dolayı görmeye bağlı yaşam kalitesi düşmüştür. [8][9][10][11] Hastalığın genç popülasyonda görülmesi sosyoekonomik ve psikolojik sorunları arttırarak yaşam kalitesini (YK) olumsuz yönde etkilemektedir.…”
