The Argus™ II retinal prosthesis: Factors affecting patient selection for implantation

Progress in Retinal and Eye Research, 2013
The Argus II epiretinal prosthesis has been developed to provide partial restoration of vision to subjects blinded from outer retinal degenerative disease. To date, the device has been implanted in multiple subjects with profound retinitis pigmentosa as part of a worldwide clinical feasibility study (clinicaltrials.gov ID: NCT00407602). The Argus II is

Argus: A universal detector at DORIS II

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1989
Abstract The detector ARGUS has been designed as a universal tool to investigate final states from e + e − annihilation processes in the energy range of the ϒ resonances. ARGUS started operation in October 1982 and has since successfully taken data at the ϒ(1S), ϒ(2S) and ϒ(4S) energies, and in the nearby continuum.

Argus II Prosthetic Vision

2020
The Argus II Retinal Prosthesis is the first, and to date only, artificial visual implant commercially approved by the U.S. Food and Drug Administration (FDA). It is indicated for patients with end-stage retinitis pigmentosa (RP) in both eyes.

Assessment of MRI issues for the Argus II Retinal Prosthesis

Magnetic Resonance Imaging, 2012
The objective was to evaluate magnetic resonance imaging (MRI) issues (magnetic field interactions, heating, artifacts and functional alterations) at 1.5 T and 3 T for the Argus II Retinal Prosthesis (Second Sight Medical Products, Sylmar, CA, USA).Standardized protocols were used to assess magnetic field interactions (translational attraction and ...

Computer-Assisted Immersive Visual Rehabilitation in Argus II Retinal Prosthesis Recipients

Ophthalmology Retina, 2020
The field of retinal prostheses is expanding. However, the best approach to training and assessing the functional benefit of postoperative vision has not been established. The purpose of this single-center prospective interventional case series was to evaluate the feasibility and effectiveness of using the Computer Assisted Rehabilitation Environment ...

Hypotony and the Argus II retinal prosthesis: causes, prevention and management

British Journal of Ophthalmology, 2019
The Argus II retinal prosthesis (Second Sight Medical Products, Sylmar, CA, USA) is an electronic epiretinal implant designed for use in patients with end-stage retinitis pigmentosa, as well as for other outer retinal degenerative conditions, such as choroideremia, Leber’s congenital amaurosis, Bardet-Biedl syndrome, Usher syndrome and rod–cone disease.

Positive Visual Phenomena Following Implantation of the Argus II Retinal Prosthesis

Ophthalmic Surgery, Lasers and Imaging Retina, 2017
A 62-year-old female who was legally blind secondary to retinitis pigmentosa (RP) developed new positive visual phenomena (PVP) (“visual storms”) following implantation of the Argus II Retinal Prosthesis System (Second Sight Medical Products, Sylmar, CA). The potential mechanisms for the exacerbating PVP or hallucinatory release phenomena are proposed.

Rehabilitation of lost functional vision with the Argus II retinal prosthesis

Canadian Journal of Ophthalmology, 2018
The Argus II retinal prosthesis is the first commercially available device for restoration of vision in patients with Retinitis Pigmentosa or with similar retinal pathology who still have minimal residual native vision. The technology is able to restore vision with production of artificial visual percepts which usually are given adequate useful ...
