"Retinitis pigmentosa is a group of genetic disorders that involves the breakdown and loss of photoreceptors in the retina, resulting in progressive retinal degeneration and eventual blindness. The Argus II Retinal Prosthesis System is the only currently available surgical implantable device approved by Health Canada. It has been shown to improve visual function in patients with severe visual loss from advanced retinitis pigmentosa. The objective of this analysis was to examine the clinical effectiveness, cost-effectiveness, budget impact, and safety of the Argus II system in improving visual function, as well as exploring patient experiences with the system."--Abstract.

Methods We performed a systematic search of the literature for studies examining the effects of the Argus II retinal prosthesis system in patients with advanced retinitis pigmentosa, and appraised the evidence according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Working Group criteria, focusing on visual function, functional outcomes, quality of life, and adv [...] This pass-through payment status covers the placement of a subconjunctival retinal prosthesis receiver and pulse generator, and the implantation of intraocular retinal electrode array with vitrectomy.8 In addition, the new technology add-on payment provides inpatient payment for the Argus II system.9 Research Questions What is the clinical effectiveness and safety of the Argus II retinal prosthe [...] What is the cost-effectiveness of the Argus II retinal prosthesis system compared with standard care in treating patients with retinitis pigmentosa in the context of the Ontario Ministry of Health and Long-Term Care? [...] What is the budget impact of implementing the Argus II system over the next 5 years from the perspective of the Ontario Ministry of Health and Long-Term Care? [...] Statistical Analysis We did not pool the results of the studies, because of the small number of studies included and the heterogeneous outcomes reported.

For the millions of people with untreatable blindness the thought of a visual prosthesis that would allow them to live a normal life has always been a distant hope. There have been intermittent bright spots that periodically fan that hope such as when Dr. Dobelle’s visual prosthesis patient drove a car in an empty parking lot. This book will serve as an update of the work in developing a visual prosthesis. Chapters discuss the physiologic and engineering issues, alternative strategies, and patents, as well as recent research studies. Visual Prosthesis - A Concise Guide is a must-have resource for ophthalmologists, neurologists, engineers and physicists.

This book presents and analyses the most recent research dedicated to restoring vision in individuals who are severely impaired or blind from retinal disease or injury. It is written by the leading groups worldwide who are at the forefront of developing artificial vision. The book begins by discussing the difficulties in comparing and interpreting functional results in the area of very low vision and the principal prospects and limitations of spatial resolution with artificial tools. Further on, chapters are included by researchers who stimulate the surface or the pigment epithelial side of the retina and by experts who work on stimulating the optic nerve, the lateral geniculate body and the superficial layers of the visual cortex. Artificial Vision: A Clinical Guide collates the most recent work of key artificial vision research groups to explain in a comparable and stringent order their varying approaches, the clinical or preclinical outcomes and their achievements during the last years. Senior ophthalmic fellows and academic practitioners will find this guide to be an indispensable resource for understanding the current status of artificial vision.

A retinal prosthesis, wherein electrical stimulation is provided to the retina of a person inflicted with outer retinal degenerative diseases such as Retinitis Pigmentosa and Age-related Macular degeneration, has been clinically tested and has succeeded in providing limited vision; such as shape recognition. It is hoped that an increased electrode count will improve visual acuity. The retinal prosthesis considered in this work is a dual-unit system with an external (outside the human body) unit and an internal (inside the body) unit with a wireless link for power and data transfer between them. Such a system poses possible health risks due to the incident electromagnetic energy of the wireless link and the power dissipated by the internal components, particularly the processing chip which drives the electrodes responsible for eliciting a neural response from the retina. Tissue damage via heating is one the primary concerns for such a system making it necessary to obtain via simulation and in-vivo and in-vitro experiments, accurate estimates of thermal elevation due to the operation of the such devices. In this work, numerical methods have been developed to compute temperature increases and electromagnetic effects due to the prosthesis components in anatomically correct human head models. The explicit and the Alternating-Direction Implicit (ADI) Finite-Difference Time-Domain (FDTD) have been used. Further, a hybrid explicit-ADI method was developed for the heat equation which provided simulation speedup of more than 10x over conventional methods for the models considered. FDTD methods were employed to compute the induced current densities and Specific Absorption Rate (SAR) in the human head due the inductive link comprising the primary coil (external) and a secondary coil (internal). Different orientations of the primary coil were considered in a frequency range of 1 MHz-20 MHz to provide guidelines for choosing eventual frequency and power parameters to conform to i.
