Will Retinal Implants Restore Vision?
Science, 2002A number of research groups are developing electrical implants that can be attached directly to the retina in an attempt to restore vision to patients suffering from retinal degeneration. However, despite promising results in animal experiments, there are still several major obstacles to overcome before retinal prostheses can be used clinically.

Suprachoroidal Implantation for the Treatment of Retinal Detachment
Ophthalmology, 1986A temporary apposition of retina and choroid has been created during retinal detachment surgery by injection of sodium hyaluronate into the suprachoroidal space in 14 patients. The iatrogenic choroidal detachment lasts at least seven to ten days, allowing adequate time for retinopexy to permanently seal the retinal hole.

Vision restoration with implants in retinal degenerations
Orvosi Hetilap, 2011Up until now there has been no available treatment for diseases causing the permanent impairment of retinal photoreceptors. Currently the development of the retinal prostheses is the earliest to promise a result that can be implemented in the clinical treatment of these patients.

A dexamethasone (DEX) intravitreal implant (OZURDEX) provides an effective treatment of inflammation secondary to branch retinal vein occlusion (BRVO). Retinal proteome changes which mediate the beneficial effects of the implant remain poorly understood.

Retinal implants: the ophthalmologist's viewpoint
IEEE SMC'99 Conference Proceedings. 1999 IEEE International Conference on Systems, Man, and Cybernetics (Cat. No.99CH37028), 2003Devices for electrical stimulation of retinal neurons were implanted into rabbit eyes using modern vitreoretinal microsurgical procedures. Biocompatibility was tested in-vivo clinically and by means of electrophysiology. Visual reactions to electrical stimulation of the inner retinal layers were recorded by means of electrical evoked cortical ...

Treatment of Cytomegalovirus Retinitis with Intraocular Implants
AORN Journal, 1998ABSTRACTCytomegalovirus (CMV) retinitis affects 20% to 40% of patients with AIDS and is the leading cause of vision loss associated with AIDS. Three treatment options currently exist (ie, IV administration of antiviral medications, intravitreal injections of ganciclovir, surgical implantation of devices that provide sustained release of ganciclovir ...

Neuromorphic algorithm for retinal implants
Conference Proceedings. 2nd International IEEE EMBS Conference on Neural Engineering, 2005., 2005The paper focuses on the input transformation for retinal implants. It describes a novel retina model, based on neurobiological measurements. Our modeling approach is neuromorphic, however the primary motivation is to derive an algorithmic skeleton from the animal retina measurements.

A New Implant for Retinal Detachment Surgery
Archives of Ophthalmology, 1963Since 1949, Dr. Custodis of Dusseldorf, Germany, has advocated a technique for the repair of retinal detachments which consists of localization of the retinal tear with indirect ophthalmoscopy and overlaying the retinal break with an imbricating scleral polyvinyl (Polyviol) implant.

Integrated wireless implants have always been the ultimate goal for neural prostheses. However, technologies are still in development and few have actually been transferred to clinical practice due to constraints in material biocompatibility, device miniaturization and flexibility.

Retinal detachment following intraocular lens implantation
Graefe's Archive for Clinical and Experimental Ophthalmology, 1981Pseudophakic retinal detachments are more difficult to manage than the phakic variety, primarily because of increased difficulties in visualizing the peripheral retina. A review of the characteristics of 70 pseudophakic retinal detachments revealed that they were similar to those following routine cataract extraction, although we noted a mild tendency ...
