Artificial means for restoring vision [PDF]

open access: yesBMJ, 2004
Degeneration of the retina occurs in age related macular degeneration and retinitis pigmentosa, resulting in loss of vision. Age related macular degeneration is a major cause of visual impairment among people over 65 in Western countries1; in the United Kingdom its incidence has increased by 30-40% over the past 40 years.2 Retinitis pigmentosa ...

North Campus Open Space Restoration Project Annual Monitoring Report: Year 2 (2019) [PDF]

open access: yes, 2020
Born out of a vision shared by the local community, students, faculty, researchers and state and federal agencies, the North Campus Open Space (NCOS) restoration project is recreating more than 40 acres of estuarine and palustrine wetlands that ...

Electro-Deformation of Fused Cells in a Microfluidic Array Device

open access: yesMicromachines, 2016
We present a new method of analyzing the deformability of fused cells in a microfluidic array device. Electrical stresses—generated by applying voltages (4–20 V) across discrete co-planar microelectrodes along the side walls of a microfluidic channel ...

The Perception-Distortion Tradeoff

open access: yes, 2019
Image restoration algorithms are typically evaluated by some distortion measure (e.g. PSNR, SSIM, IFC, VIF) or by human opinion scores that quantify perceived perceptual quality.

Perceptual restoration fails to recover unconscious processing for smooth eye movements after occipital stroke

open access: yeseLife, 2022
The visual pathways that guide actions do not necessarily mediate conscious perception. Patients with primary visual cortex (V1) damage lose conscious perception but often retain unconscious abilities (e.g. blindsight). Here, we asked if saccade accuracy

Non-viral delivery and optimized optogenetic stimulation of retinal ganglion cells led to behavioral restoration of vision [PDF]

open access: yes, 2012
Stimulation of retinal neurons using optogenetics via use of chanelrhodopsin-2 (ChR2) has opened up a new direction for restoration of vision for treatment of retinitis pigmentosa (RP).

Regenerative Nanomedicine for Vision Restoration [PDF]

open access: yesMayo Clinic Proceedings, 2013
Herein, we discuss recent applications of nanotechnology to ophthalmology, including nanoparticles for drug, gene, and trophic factor delivery; regenerative medicine (in the areas of optogenetics and optic nerve regeneration); and diagnostics (eg, minimally invasive biometric monitoring).

Restoring vision at the fovea

open access: yesCurrent Opinion in Behavioral Sciences, 2019
In humans high quality, high acuity visual experience is mediated by the fovea, a tiny, specialized patch of retina containing the locus of fixation. Despite this, vision restoration strategies are typically developed in animal models without a fovea. While electrical prostheses have been approved by regulators, as yet they have failed to restore high ...

Small Interfering RNA Targeted to ASPP2 Promotes Progression of Experimental Proliferative Vitreoretinopathy

open access: yesMediators of Inflammation, 2016
Background. Epithelial-mesenchymal transition (EMT) of retinal pigment epithelium (RPE) is vital in proliferative vitreoretinopathy (PVR) development.
