Pupil responses derived from outer and inner retinal photo reception are normal in patients with hereditary optic neuropathy

We compared the pupil responses originating from outer versus inner retinal photoreception between patients with isolated hereditary optic neuropathy (HON, n = 8) and healthy controls (n = 8). Three different testing protocols were used. For the first two ...

Self-organisation of motion features with a temporal asynchronous dynamic vision sensor

Neural circuits closer to the periphery tend to be organised in a topological way, i.e. stimuli which are spatially close tend to be mapped onto neighbouring processing neurons. The goal of this study is to show how motion features (optic-flow), which have ...

Chiasmatic Infiltration Secondary to Late Malignant Transformation of Retinoma

Alessia Pica

Purpose: To report the lethal course of malignant transformation of retinoma in an adult. Methods: Case report. A 40-year-old patient presented with retinoma in his right eye and retinoblastoma in his left eye. Enucleation was recommended but refused and t ...

MP2RAGE multiple sclerosis magnetic resonance imaging at 3 T

Rolf Gruetter, Tobias Kober, Delphine Ribes Lemay, Reto Meuli, Cristina Granziera

Objectives: Lesion detection and characterization in multiple sclerosis (MS) are an essential part of its clinical diagnosis and an important research field. In this pilot study, we applied the recently introduced two inversion-contrast magnetization-prepa ...

Design and validation of a telemetrically drived implantable glaucoma drainage device

Adan Villamarin

Glaucoma is one of the leading cause of irreversible blindness in the world and it usually occurs when the pressure inside the eyes gradually rises, permanently damaging the optic nerve. Medications and filtering surgery are two possible therapies availabl ...

Tomographie en cohérence optique dans le domaine de Fourier appliquée aux tissus humains

Roland Michaely

Fourier Domain Optical Coherence Tomography FDOCT is a recent imaging technique based on the principle of Low Coherence Interferometry. In FDOCT cross-sectional images of diffusing objects are synthesised from a measure of backscattered light. The main adv ...

Induction of brain aquaporin 9 (AQP9) in catecholaminergic neurons in diabetic rats

Pierre Magistretti, Jean-Marie Petit

Aquaporin 9 facilitates the diffusion of water but also glycerol and monocarboxylates, known as brain energy substrates. AQP9 was recently observed in catecholaminergic neurons that are implicated in energy homeostasis and also possibly in neuroendocrine e ...

Vectorial retinal blood flow and optical vessel vivisection for 3D angiography with high resolution resonant Doppler OCT

Theo Lasser, Rainer Leitgeb, Martin Villiger, Adrian Bachmann, Roland Michaely, Cédric Blatter

PURPOSE: To perform high speed and completely non-invasive 3D angiography at the optic nerve head region and to reconstruct vectorial 3D blood flow from optically segmented blood vessel structure as a pre-requisite for testing retinal function and physiolo ...

Measurement of retinal physiology using functional Fourier domain OCT concepts

Theo Lasser, Christophe Pache, Rainer Leitgeb, Martin Villiger, Adrian Bachmann, Roland Michaely, Cédric Blatter

Fourier Domain OCT proved to be an outstanding tool for measuring 3D retinal structures with high sensitivity, resolution, and speed. We extended the FDOCT concept towards functional imaging by analyzing the spectroscopic tissue properties, polarization co ...

The tyrp1-Tag/tyrp1-FGFR1-DN bigenic mouse: a model for selective inhibition of tumor development, angiogenesis, and invasion into the neural tissue by blockade of fibroblast growth factor receptor activity

Friedrich Beermann

We describe herein a new transgenic mouse tumor model in which fibroblast growth factor (FGF) receptor activity is selectively inhibited. Tyrp1-Tag mice that develop early vascularized tumors of the retinal pigment epithelium were crossed with tyrp1-FGFR1- ...
