Factors Affecting Perceptual Threshold in Argus II Retinal Prosthesis Subjects.
PURPOSE The Argus II epiretinal prosthesis has been developed to provide partial restoration of vision to subjects blinded from outer retinal degenerative disease. Participants were surgically implanted with the system in the United States and Europe in a single arm, prospective, multicenter clinical trial. The purpose of this investigation was to determine which factors affect electrical thres...
متن کاملUse of the Argus II retinal prosthesis to improve visual guidance of fine hand movements.
PURPOSE We studied the capabilities of the Argus II retinal prosthesis for guiding fine hand movement, and demonstrated and quantified guidance improvement when using the device over when not using the device for progressively less predictable trajectories. METHODS A total of 21 patients with retinitis pigmentosa (RP), remaining vision no more than bare light perception, and an implanted Argu...
متن کاملAssessment of MRI issues for the Argus II retinal prosthesis.
OBJECTIVE 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). MATERIALS AND METHODS Standardized protocols were used to assess magnetic field interactions (translational attraction and torque; 3 T,...
متن کاملRetinotopic to Spatiotopic Mapping in Blind Patients Implanted With the Argus II Retinal Prosthesis.
Purpose To quantify the precision of mapping from retinotopic (retina-centered) to spatiotopic (world-centered) coordinates in blind humans implanted with a retinal prosthesis device. Additionally, to demonstrate that an eye tracker can be calibrated on sightless patients based on the percept from a visual implant. Methods We directly activated epiretinal electrodes to create retinotopic stim...
متن کاملVisual BOLD Response in Late Blind Subjects with Argus II Retinal Prosthesis
Retinal prosthesis technologies require that the visual system downstream of the retinal circuitry be capable of transmitting and elaborating visual signals. We studied the capability of plastic remodeling in late blind subjects implanted with the Argus II Retinal Prosthesis with psychophysics and functional MRI (fMRI). After surgery, six out of seven retinitis pigmentosa (RP) blind subjects we...
