PROBLEM TO BE SOLVED: To provide a fundus camera which is capable of taking a quality fundus picture even in a non-dilatation mode that reduces a papillary diameter. SOLUTION: The infrared light for observation is emitted from the optical systems, 10, 20, for illumination through a sclera Ec (a white portion of the eyes) of a subject's eye before an image of the fundus Er uniformly illuminated by the infrared light is observed on a monitoring screen 38. A fundus image is taken by CCD 35 through the pupil Ep when the stroboscopic light, 14, 24, is emitted and stored thereafter in a storage device 39. Since the fundus is illuminated in this system, and a fundus image is taken by allowing the illuminating light to pass through a scleral portion of the subject's eye and the light reflected from the fundus to pass through the pupil Ep, an extensively bright quality fundus image is available as the reflected light that passes a larger effective range of a pupillary diameter is utilized for photography even when the pupillary diameter becomes smaller. |
