Laboratory and clinical reliability of conformally coated subretinal implants
Despite recent developments and new treatments in ophthalmology there is nothing available to cure retinal degenerations like Retinitis Pigmentosa (RP) yet. One of the most advanced approaches to treat people that have gone blind due to RP is to replace the function of the degenerated photoreceptors by a microelectronic neuroprosthetic device. Basically, this subretinal active implant transform...
متن کاملNeuroprotective effect of subretinal implants in the RCS rat.
PURPOSE Retinal prosthetics have been designed to interface with the neural retina by electrically stimulating the remaining retinal circuits after photoreceptor degeneration. However, the electrical stimulation provided by the subretinal implant may also stimulate neurotrophic factors that provide neuroprotection to the retina. This study was undertaken to determine whether electrical stimulat...
متن کاملExtraocular Surgical Approach for Placement of Subretinal Implants in Blind Patients: Lessons from Cochlear-Implants
In hereditary retinal diseases photoreceptors progressively degenerate, often causing blindness without therapy being available. Newly developed subretinal implants can substitute functions of photoreceptors. Retina implant extraocular surgical technique relies strongly on cochlear-implant know-how. However, a completely new surgical approach providing safe handling of the photosensor array had...
متن کاملSubretinal surgery for peripapillary subretinal neovascular membranes.
PURPOSE To report the results of surgical removal of extrafoveal peripapillary subretinal neovascular membranes (PSRNVMs) for elderly patients in whom visual acuity was threatened or affected by subretinal fluid, subretinal hemorrhage, subretinal exudate, or PSRNVM growth toward the fovea. METHODS Retrospective review of six eyes of six patients undergoing subretinal surgical removal of PSRNV...
متن کاملVisualisation of active subretinal implants with external connections by high-resolution CT.
Two patients carrying an active subretinal implant with extra-ocular parts were examined by high-resolution CT. Cranial scans were acquired in the primary position and in eight additional directions of gaze with eyes open and closed to demonstrate the mobility of the eyeball and the implant within the orbital cavity. Three-dimensional images were constructed to visualise the path of the implant...
