Successful Long-Term Implantation of Electrically Inactive Epiretinal Microelectrode Arrays in Rabbits

Abstract: Tack fixation of electrode arrays for electric stimulation of the inner retinal surface seems to be a useful approach in long-term implantation of an epiretinal prosthesis.

“…Before a retinal prosthesis can be implanted in humans it is essential to verify that it will not cause any harm. This requires an assessment of both the implant biocompatibility [17][18][19][20][21][22][23] as well as any potential damage that could be caused by chronic electrical stimulation [24][25][26] . Experience with similar neural prostheses, such as the cochlear implant, provides insight into the broad range of stimulation, and physical, parameters that do not cause tissue damage 27 .…”

“…Retinal tacks have been shown to be suitable for bringing the microelectrode array in close contact to the retinal surface. 12,13 Stable positioning is a prerequisite to ensure successful activation. From clinical applications in the repair of giant retinal tears, it was reported that a glial reaction adjacent to the tack may occur.…”

“…As pesquisas dos implantes retinianos objetivam o desenvolvimento de próteses que estimulem diretamente componentes neuronais do sistema visual para promover alguma percepção visual útil em pacientes cegos por doenças degenerativas retinianas (52)(53)(54)(55)(56)(57)(58)(59)(60)(61)(62)(63)(64)(65) . Pacientes portadores de RP apresentam grande perda visual, o que os torna bons candidatos para uma prótese retiniana, por lhes ser útil qualquer melhora significativa na visão.…”
