Book excerpt: The field of retinal prosthetics has seen significant advances in the past 3 decades. Encouraging results from different groups have shown coarse objective functional improvement, using a range of technological and surgical approaches. The Argus II retinal prosthesis system was the first of its kind to receive regulatory approval for commercial use in Europe and the USA. The device is designed to replicate the function of photoreceptors in converting visual information into electrical neural signals in patients with profound visual loss secondary to degenerative retinal disease. Results from a phase II study of 30 patients have demonstrated improved performance in basic tests of visual function, object recognition, letter reading, prehension, orientation and mobility tasks. It is now the most widely implanted retinal prosthetic device worldwide. This chapter provides an overview of the requirements of a retinal prosthetic system, the results from the Argus II device to date, and an insight into some of the challenges and future directions of visually restorative therapies.

Book excerpt: 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.

Download or read book Macular Surgery written by Andrew Chang and published by Springer Nature. This book was released on 2020-10-30 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent technological advances in the diagnosis of macular disorders have enhanced our understanding of these diseases. At the same time, advances in small-gauge vitrectomy instrumentation and techniques have improved the safety and efficiency of surgery, allowing macular conditions that would have otherwise resulted in blindness to be treated effectively, preserving patients’ sight. Macular surgery continues to evolve rapidly, thanks to exciting future technology trends. This book provides a detailed and up-to-date overview of the field. It begins with essential information on macular anatomy and pathophysiology, examination techniques, and surgical instrumentation. In turn, it discusses a broad range of disease processes, including macular holes, epiretinal membrane, vitreomacular traction and myopic maculopathy. The role and benefits of advanced vitrectomy techniques including submacular surgery, prosthetic vision, robotic surgery, and stem cell and gene therapy are addressed in detail. A review of perioperative care and potential complications rounds out the coverage.

Available in PDF, EPUB and Kindle. Book excerpt: "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.
