Visual and Non-Visual Navigation in Blind Patients with a Retinal Prosthesis. [PDF]
PLoS ONE, 2015 Human adults with normal vision can combine visual landmark and non-visual self-motion cues to improve their navigational precision. Here we asked whether blind individuals treated with a retinal prosthesis could also benefit from using the resultant new

Temporary Kerato-Prosthesis to Resolve Traumatic Loss of a Healed Corneal Button
Case Reports in Ophthalmology, 2021 The aim of this study is to report a rare case of traumatic complete loss of a donor corneal button successfully resolved by a 24-h implantation of a temporary kerato-prosthesis. A healthy 30-year-old man with a history of prior penetrating keratoplasty (

Optogenetic approaches to retinal prosthesis [PDF]
Visual Neuroscience, 2014 AbstractThe concept of visual restoration via retinal prosthesis arguably started in 1992 with the discovery that some of the retinal cells were still intact in those with the retinitis pigmentosa disease. Two decades later, the first commercially available devices have the capability to allow users to identify basic shapes. Such devices are still very

Dampening Spontaneous Activity Improves the Light Sensitivity and Spatial Acuity of Optogenetic Retinal Prosthetic Responses [PDF]
, 2016 Retinitis pigmentosa is a progressive retinal dystrophy that causes irreversible visual impairment and blindness. Retinal prostheses currently represent the only clinically available vision-restoring treatment, but the quality of vision returned remains ...

The role of the host—Neutrophil biology
Periodontology 2000, EarlyView., 2023 Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...
