Enhancing Electroretinogram Classification with Multi-Wavelet Analysis and Visual Transformer
Sensors, 2023 The electroretinogram (ERG) is a clinical test that records the retina’s electrical response to light. Analysis of the ERG signal offers a promising way to study different retinal diseases and disorders.

Preliminary study on electrophysiological changes after cellular autograft in age-related macular degeneration [PDF]
, 2014 Background: Evolving atrophic macular degeneration represents at least 80% of all macular degenerations and is currently without a standardized care. Autologous fat transplantation (AFT) efficacy was demonstrated by several studies, since these cells are

Multifocal Electroretinograms [PDF]
Journal of Visualized Experiments, 2011 A limitation of traditional full-field electroretinograms (ERG) for the diagnosis of retinopathy is lack of sensitivity. Generally, ERG results are normal unless more than approximately 20% of the retina is affected. In practical terms, a patient might be legally blind as a result of macular degeneration or other scotomas and still appear normal ...

Rhythms of Locomotion Expressed by Limulus polyphemus, the American Horseshoe Crab: II. Relationship to Circadian Rhythms of Visual Sensitivity [PDF]
, 2008 In the laboratory, horseshoe crabs express a circadian rhythm of visual sensitivity as well as daily and circatidal rhythms of locomotion. The major goal of this investigation was to determine whether the circadian clock underlying changes in visual ...

Functional deficits precede structural lesions in mice with high-fat diet-induced diabetic retinopathy [PDF]
, 2016 Obesity predisposes to human type 2 diabetes, the most common cause of diabetic retinopathy. To determine if high-fat diet–induced diabetes in mice can model retinal disease, we weaned mice to chow or a high-fat diet and tested the hypothesis that diet ...
