Abstract

La présente invention concerne un ophtalmoscope indirect vertical comprenant une première partie formant corps et une partie faisant passer la lumière. La première partie formant corps comprend une partie d'observation où les yeux d'un patient à examiner sont positionnés et une partie d'optométrie où une partie d'optométrie d'un examinateur est positionnée. La partie faisant passer l'image est prévue dans la partie intérieure de la première partie formant corps et envoie une image de fond d'œil issue du patient à examiner à l'examinateur, l'image de fond d'œil étant soumise à la réfraction et à la réflexion et envoyée et une image d'œil externe étant envoyée directement. En conséquence, l'examinateur peut examiner et traiter un patient à examiner par l'intermédiaire d'une image de fond d'œil ayant les mêmes positions droite et gauche et haute et basse, et une aptitude à l'emploi améliorée est obtenue.
