Abstract
An eye fundus photographing system, wherein a three-dimensional moving picture is photographed and displayed in eye fundus of infrared fluorescent photographing. The photographing system includes an exciter filter for transmitting a specific wavelength region of the illumination light emitted from the light source, an illumination optical system for irradiating the fundus with the illumination light transmitted from the exciter filter, left and right objective lenses for extracting the infrared fluorescent light emitted by an ICG of the eye fundus as a left and right photographing light, a photographing optical system including a barrier filter for transmitting the predetermined infrared wavelength region of the left and right photographic light, infrared TV cameras for photographing this wavelength region with a predetermined frame rate, a synchronizing cable for synchronizing each frame and a displayed three-dimensional moving image obtained by combining a left and right photographic image by the infrared TV camera.
