Ophthalmic system and method for clinical device using transcleral illumination with multiple points source

Christophe Moser, Timothé Laforest, Mathieu Künzi

An ophthalmic illumination and imaging system with transscleral / transpalpebral illumination of the eye fundus comprises a light-delivering device with a plurality of emitting areas; each of the emitting areas being configured to be independently controll ...

The Little W-Net That Could: State-of-the-Art Retinal Vessel Segmentation with Minimalistic Models

André Anjos

The segmentation of the retinal vasculature from eye fundus images represents one of the most fundamental tasks in retinal image analysis. Over recent years, increasingly complex approaches based on sophisticated Convolutional Neural Network architectures ...

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 ...

The role of optic flow pooling in insect flight control in cluttered environments

Dario Floreano, Julien Jean Denis Nicolas Lecoeur, Emily Baird

Flight through cluttered environments, such as forests, poses great challenges for animals and machines alike because even small changes in flight path may lead to collisions with nearby obstacles. When flying along narrow corridors, insects use the magnit ...

System, method and apparatus for retinal absorption phase and dark field imaging with oblique illumination

Christophe Moser, Timothé Laforest, Mathieu Künzi, Dino Carpentras

A method for imaging a tissue of an eye, the method including the steps of providing oblique illumination to the eye by a plurality of light emitting areas of a light delivery device, the plurality of light emitting areas being independently controllable a ...

Landmark Detection for Fusion of Fundus and MRI Toward a Patient-Specific Multimodal Eye Model

Meritxell Bach Cuadra, Carlos Ciller

Ophthalmologists typically acquire different image modalities to diagnose eye pathologies. They comprise, e.g., Fundus photography, optical coherence tomography, computed tomography, and magnetic resonance imaging (MRI). Yet, these images are often complem ...

An artificial elementary eye with optic flow detection and compositional properties

Dario Floreano, Ramon Pericet Camara, Michal Karol Dobrzynski

We describe a 2 mg artificial elementary eye whose structure and functionality is inspired by compound eye ommatidia. Its optical sensitivity and electronic architecture are sufficient to generate the required signals for the measurement of local optic flo ...

Novel ADAM9 homozygous mutation in a consanguineous Egyptian family with severe cone-rod dystrophy and cataract

Tatiana Favez

Objective To genetically and phenotypically describe a new ADAM9 homozygous mutation in a consanguineous family from Egypt with autosomal recessive cone-rod dystrophy (arCRD), anterior polar and posterior subcapsular cataract. Design, setting and participa ...

A novel homozygous R764H mutation in crumbs homolog 1 causes autosomal recessive retinitis pigmentosa

Purpose: Retinitis pigmentosa (RP; MIM 268000) is a hereditary disease characterized by poor night vision and progressive loss of photoreceptors, eventually leading to blindness. This degenerative process primarily affects peripheral vision due to the loss ...

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 ...
