A new concept for visual aids: "ViSAR" Visual Signal Adaptive Restitution.

This paper introduces a new visual device concept for patients with partially sight loss named Visual Signal Adaptive Restitution (ViSAR). This new concept adapt the signal visual itself to the patient's visual discomfort in real time. While most device tends to compensate for physiology anomaly, ViSAR concept allows to improve the patient-signal interaction and to favor an active vision.

SLO angiography: arterio-venous filling times in monkey and minipig.

Confocal scanning laser ophthalmoscope (cSLO) is a new technique which enables ocular fundus image recording and dynamic retinal angiography to be performed. The ocular fundus image is acquired sequentially, point by point, and is reconstructed on a video monitor at the rate of 25 images per second. The aim of this paper is to evaluate the feasibility of measuring retinal arterio-venous filling times (AVFT) with a I + Tech cSLO.
