Sight restoration
Cases of sight onset after extended periods of congenital blindness provide windows into visual development and brain plasticity. Such cases are extremely rare in the developed world. Here, we make the argument that in meeting a public health challenge in the developing world, that of providing treatment to curably blind children, we have the opportunity to have a beneficial impact on science a...
متن کاملRestoration of Sight with Photovoltaic Subretinal Prosethesis
Patients with retinal degeneration lose sight due to gradual demise of photoreceptors. Electrical stimulation of the surviving retinal neurons provides an alternative route for delivery of visual information. Subretinal photovoltaic arrays with 70m pixels were used to convert pulsed near-IR light (880-915nm) into pulsed current to stimulate the nearby inner retinal neurons. Network-mediated re...
متن کاملThe Eye Bank for Sight Restoration, Inc.
Part 1271.85 a (5) Syphilis testing should not be required for eye tissue. Dr. Marian Macsai et al documented that syphilis is not transmitted from donor to recipient by cornea1 transplant. Dr. Jay Pepose documented the ineffectiveness of using syphilis testing as a marker for other diseases. Additionally, unnecessary syphilis screening would result in a 7.5% increase in the cost of serology te...
متن کاملElectronic approaches to restoration of sight.
Retinal prostheses are a promising means for restoring sight to patients blinded by the gradual atrophy of photoreceptors due to retinal degeneration. They are designed to reintroduce information into the visual system by electrically stimulating surviving neurons in the retina. This review outlines the concepts and technologies behind two major approaches to retinal prosthetics: epiretinal and...
متن کاملHolographic display system for restoration of sight to the blind.
OBJECTIVE We present a holographic near-the-eye display system enabling optical approaches for sight restoration to the blind, such as photovoltaic retinal prosthesis, optogenetic and other photoactivation techniques. We compare it with conventional liquid crystal displays (LCD) or digital light processing (DLP)-based displays in terms of image quality, field of view, optical efficiency and saf...
