Title
(EN) OPTICAL COHERENCE TOMOGRAPHY SYSTEM
(FR) SYSTÈME DE TOMOGRAPHIE PAR COHÉRENCE OPTIQUE
Abstract
(EN)
An OCT system comprises an OCT scan module for retinal scanning and an add-on anterior segment scanning module which includes at least one anterior segment scan lens (11) and an add-on fixation target (15) which is used to maintain the viewing direction of the eye (6) under investigation while achieving anterior segment scanning. Because the anterior segment scan module added to the exterior of an existing OCT system for retinal scanning has an add-on fixation target (15), it is possible to maintain the viewing direction of the eye (6) under investigation while carrying out anterior segment scanning without adjusting the internal beam path of the OCT system, and the OCT system of the present invention can be adapted to patients with only one functioning eye.
(FR)
La présente invention concerne un système d'OCT qui comprend un module de balayage OCT pour le balayage de la rétine et module complémentaire de balayage de segment antérieur qui comprend au moins une lentille de balayage de segment antérieur (11) et une cible de fixation complémentaire (15) qui est utilisée pour maintenir la direction de visualisation de l’œil (6) en cours d'examen tout en réalisant le balayage de segment antérieur. Etant donné que le module de balayage de segment antérieur ajouté sur l'extérieur d'un système OCT existant pour le balayage rétinien a une cible de fixation complémentaire (15), il est possible de maintenir la direction de visualisation de l’œil (6) en cours d'examen tout en réalisant un balayage de segment antérieur sans ajuster la trajectoire de faisceau interne du système OCT, et le système OCT de la présente invention peut être adapté aux patients n'ayant qu'un seul œil qui fonctionne.
