摘要： A stimulus light from a stimulus light source is projected to the retina of an ocular fundus under examination to stimulate the retina in localized fashion to generate a bioelectric signal from the retina. The stimulus light source is mounted on a movable block, and an operating lever is used to move the stimulus light source to change the stimulus light on the retina. The size of the stimulus light can also be varied using a panel having a plurality of openings with different diameters for allowing the stimulus light to pass through. This assures a reliable local ERG examination because the bioelectrical signal can be produced in a wider area of the retina. The operating lever is further fixed by inserting a cap to keep the projected stimulus light unchanged. This allows the burden on the examiner to be reduced remarkably, assuring a reliable local ERG examination.

摘要： Stimulus light is projected from a stimulus light source onto an ocular fundus of an eye under examination to locally stimulate the retina in order to perform a biological examination. During a biological examination, first background light is projected from an illumination light source via an objective lens, and second background light is projected from a light source from the periphery of the objective lens onto the ocular fundus. During alignment prior to a biological examination, the first background light is turned off and the second background light is projected onto the ocular fundus. During observation of the ocular fundus, the first background light projected onto the fundus is blocked, so that fundus observation or eye fixation is not disturbed by the background light. This enables accurate alignment to be carried out. Since the examinee's eye is irradiated with the second background light from the periphery of the objective lens in preparation for a biological examination, the examinee's eye can sufficiently adapt to the light during a biological examination, ensuring a reliable biological examination.

摘要： An ophthalmic photographic apparatus is provided that is readily able to capture dynamic and still eye fundus images by infrared light-excited fluorescence. A CCD device that is sensitive to infrared light is used to capture images of the eye fundus as dynamic and still images. When the shutter button is pressed, infrared light-excited fluorescence images are obtained as still images and stored in a recording unit. The infrared light-excited fluorescence image of the eye fundus is captured as a still image with or without a flash from a strobe light source. Such an arrangement makes it possible to capture still images even when dynamic images are being recorded.

摘要： An ophthalmic photographic apparatus comprises a photographic mask for defining a fundus photography range, a photographic stop for eliminating light reflected from an anterior portion of the eye, and a focusing lens for bringing the fundus into focus. Interlocking means are provided to move the photographic mask and the photographic stop in an interlocked manner relative to the movement of the focusing lens in such a way that with respect to a photographic optical system the photographic mask may be kept at a position substantially conjugate with an imaging plane of a CCD and the photographic stop may be kept at a position substantially conjugate with an anterior portion of the eye. The CCD is located at the image-side focal plane of the image-formation lens, the mask is located on the object-side focal plane of the focusing lens, and the photographic stop is located on the image-side focal plane of the focusing lens. These three components are moved as one unit when the system is adjusted to focus on the fundus.

摘要： An ophthalmologic examination apparatus has a main unit housing an illuminating optical system that illuminates a fundus of a subject's eye to be examined and an imaging optical system that images the illuminated eye fundus. First and second attachment units are removably and exchangeably mounted to the main unit for providing different ophthalmologic functions. The first attachment unit houses an imaging device that captures an image of the eye fundus via the imaging optical system housed in the main unit. The second attachment unit houses a light source that emits stimulating light for an electroretinogram and which is projected onto the eye fundus via the imaging optical system housed in the main unit.
