Photovoltaic stimulation of retinal microcircuit for vision restoration

Sight restoration through retinal prostheses was still a mere dream a century ago. Current challenges are even greater: providing a quantitatively and qualitatively useful artificial vision to late blind patients. Existing approaches all face engineering a ...

Optical phase contrast imaging of human retinal cells by changing the tissue refractive index

Christophe Moser, Timothé Laforest, Laura Emmanuelle Kowalczuk, Mathieu Künzi

Purpose : Based on oblique partially coherent illumination of transparent samples, we developed a simple custom Optical Phase Imaging (OPI) microscope providing a label-free, semi-quantitative phase contrast imaging. The aim of this study was to explore th ...

(Un)crowding modulates recurrent connectivity in the visual cortex

Michael Herzog, Vitaly Chicherov, Maya Anna Jastrzebowska

Introduction: In crowding, neighboring elements impede the perception of a target. Surprisingly, increasing the number of neighboring elements can decrease crowding, i.e., lead to uncrowding (Manassi et al., 2015). Few neuroimaging studies have explored th ...

The role of one-shot learning in #TheDress

Michael Herzog, Adrien Christophe Doerig

#TheDress is remarkable in two aspects. First, there is a bimodal split of the population in the perception of the dress's colors (white/gold vs. black/blue). Second, whereas interobserver variance is high, intra-observer variance is low, i. e., the percep ...

The role of one-shot learning in #TheDress

Michael Herzog, Adrien Christophe Doerig, Leila Drissi Daoudi - Kleinbauer

The first amazing effect with #TheDress is that a large number of people perceive it as white and gold even though the true colors of the dress are black and blue. Such apparent changes in color are common in many illusions. What makes #TheDress even more ...

Comparison of acute non-visual bright light responses in patients with optic nerve disease, glaucoma and healthy controls

Lorette Leon

This study examined the effect of optic nerve disease, hence retinal ganglion cell loss, on nonvisual functions related to melanopsin signalling. Test subjects were patients with bilateral visual loss and optic atrophy from either hereditary optic neuropat ...

Cone-Rod Dystrophy Caused by a Novel Homozygous RPE65 Mutation in Leber Congenital Amaurosis

Background: The aim of this study was to describe an unexpected phenotype in a family with Leber congenital amaurosis (LCA) due to a retinal pigment epithelium-specific protein 65 kDa (RPE65) homozygous mutation. History and Signs: We analyzed a family fro ...

Photodynamic therapy for polypoidal choroidal vasculopathy

Hubert van den Bergh, Patrycja Nowak-Sliwinska

The first effective therapy for exudative macular degeneration (AMD) was Photodynamic Therapy (PDT). Diagnosis of the disease was to a large extent by fluorescein angiography (FA). Distinguishing between the leaky choroidal neovessels (CNV) associated with ...

Angiogenesis inhibition for the improvement of photodynamic therapy: The revival of a promising idea

Hubert van den Bergh, Patrycja Nowak-Sliwinska

Photodynamic therapy (PDT) is a minimally invasive form of treatment, which is clinically approved for the treatment of angiogenic disorders, including certain forms of cancer and neovascular eye diseases. Although the concept of PDT has existed for a long ...

Capturing lightness between contours

Marcus Leonardus Vergeer

Homogeneously coloured bars may exhibit lightness differences at the intersections. A well-known example is the Hermann grid illusion, where crossing white bars on a black background show dark patches at the crossings. Jung (1973, Handbook of Sensory Physi ...
