Homogeneous light stimulation of melanopsin and cones with a Maxwellian view device for the human eye

Patrick Robert Flückiger, Gilles Evéquoz

We designed and tested a device to stimulate specifically one photoreceptor type, or a combination of some of them, of the human eye by using up to six primaries. The device produces a homogeneous light field over 40 degrees which is projected onto the ret ...

The Impact of Light Distribution and Furniture Layout on Meeting Light Exposure Objectives in an Office – A Simulation Case Study

Marilyne Andersen, Siobhan Francois Rockcastle, Steffen Lutz Hartmeyer, Megan Nicole Danell

The present simulation case study compares the impact of electric lighting distributions in relation to work-desk location and orientation on work-plane and eye-level illumination within a small private office. The aim of this study is to better understand ...

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 ...

3-Dimensional magnetic resonance imaging of the freely moving human eye

Josefina Adriana Maria Bastiaansen, Silvio Ionta, João Pedro Forjaco Jorge, Jérôme Yerly, Lorenzo Di Sopra

Eye motion is a major confound for magnetic resonance imaging (MRI) in neuroscience or ophthalmology. Currently, solutions toward eye stabilisation include participants fixating or administration of paralytics/anaesthetics. We developed a novel MRI protoco ...

MRI-based brain volumetry and retinal optical coherence tomography as the biomarkers of outcome in acute methanol poisoning

Tobias Kober, Bénédicte Marie Maréchal

Background: Basal ganglia lesions are typical findings on magnetic resonance imaging (MRI) of the brain in survivors of acute methanol poisoning. However, no data are available on the association between the magnitude of damaged brain regions, serum concen ...

Full field dependence of primary aberrations in perturbed double-plane symmetric systems with a circular pupil

Toralf Scharf, Alessandro Grosso

This paper deals with the theory of primary aberrations for perturbed double-plane symmetric optical systems consisting of a combination of tilted and decentered surfaces and a circular pupil. First, the analytical expressions describing the full field beh ...

Novel PDE6B Mutation Presenting with Retinitis Pigmentosa - A Case Series of Three Patients

Daniel Francis Schorderet

Background Retinitis pigmentosa (RP) affects 2.5 million people worldwide. Increased identification of causative gene defects and the increasing possibility of treatment necessitates better knowledge of phenotype-genotype correlations to help identify pati ...

Sparse Lens Inversion Technique (SLIT): lens and source separability from linear inversion of the source reconstruction problem

Frédéric Courbin, Rémy Elie Joseph

Strong gravitational lensing offers a wealth of astrophysical information on the background source it affects, provided the lensed source can be reconstructed as if it was seen in the absence of lensing. In the present work, we illustrate how sparse optimi ...

Reduced metabolic function and structural alterations in inherited retinal dystrophies: investigating the effect of peripapillary vessel oxygen saturation and vascular diameter on the retinal nerve fibre layer thickness

PurposeTo evaluate the relationship between the peripapillary metabolic alterations [retinal vessel Oximetry (RO)] and the structural findings [retinal vessel diameter and retinal nerve fibre layer thickness (RNFL)] in patients with inherited retinal dystr ...

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 ...

A New Adjustable Glaucoma Drainage Device

Nikolaos Stergiopoulos, Sylvain Roy, Adan Villamarin, Stéphane Bigler

PURPOSE. This work is focused on the testing of a new experimental noninvasively adjustable glaucoma drainage device (AGDD) that allows for the control of its outflow resistance to modulate intraocular pressure (IOP) in a customized fashion. METHODS. Six A ...

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 ...

Development of Minimally-Invasive Optical Methods to Individualize the Doses Used for Therapeutic Applications of Light

Despite the experience gained over several decades in various types of light-based medical treatments, the optimization of the corresponding therapeutic protocols and accurate forecasting of their outcome have not yet been achieved in many cases. The diffi ...

Optische Augenlängenmessung für klinische Anwendungen

Beate Möller

Cataract is the leading cause of blindness worldwide. The clouding of the human eye lens is called "Grauer Star" in German. In the industrialized countries this process of increased blindness is corrected by the surgical removal of the clouded lens and its ...
