Photovoltaic stimulation of retinal microcircuit for vision restoration

Naïg Aurelia Ludmilla Chenais

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 ...

Microsaccades Distinguish Looking From Seeing

Andreas Sonderegger, Andrea Regula Schneider

Understanding our visual world requires both looking and seeing. Dissociation of these processes can result in the phenomenon of inattentional blindness or 'looking without seeing'. Concomitant errors in applied settings can be serious, and even deadly. Cu ...

Closed-Form Solution to Disambiguate Defocus Blur in Single-Perspective Images

Sabine Süsstrunk, Majed El Helou, Marjan Shahpaski

Depth-from-defocus techniques suffer an ambiguity problem where depth planes on opposite sides of the focal plane have identical defocus. We solve the ambiguity by relying on the wavelength-dependent relationship between defocus and depth. We conduct a rob ...

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

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 ...

Enhanced Compressed Look-up-Table Based Real-Time Rectification Hardware

Yusuf Leblebici, Alexandre Schmid, Abdulkadir Akin, Halima Najibi, Luis Manuel Gaemperle

Real-time disparity estimation requires real-time rectification which involves solving the models of lens distortions, image translations and rotations. Low complexity look-up-table based rectification algorithms usually require an external memory to store ...

Modelling 'non-visual' effects of daylighting in a residential environment

Marilyne Andersen, Sharon Jane Gochenour

The importance of light not only as a therapeutic tool but as an essential element of healthy living has been highlighted by the recent discovery of a specialized photoreceptor in the eye responsible for synchronizing our internal circadian pacemaker. This ...

Notch Signaling in Pigment Cells and Generation of Mouse Models for Ocular Diseases

Bhushan Sarode

Cellular signaling mediated by Notch receptors results in coordinated regulation of cell growth, survival and differentiation. In melanocytes, Notch signaling is essential for the maintenance of melanocytes and the melanocyte stem cell population. Whereas, ...

Effects of prior light exposure on early evening performance, subjective sleepiness, and hormonal secretion

Jean-Louis Scartezzini, Friedrich Linhart, Mirjam Münch, Apiparn Borisuit

In sighted humans, light intensity, timing, exposure duration, and spectral composition of light are important to entrain the endogenous circadian pacemaker to the 24-h day-night cycle. We tested the impact of two realistic office lighting conditions durin ...
