摘要： This ophthalmologic device is provided with a light source, an iris diaphragm, a light condensing member, a slit, and an image sensor. The light source can be arranged at a position that is substantially optically conjugated with the iris of an eye to be examined. The iris diaphragm is arranged at a position that is substantially optically conjugated with the light source, in which an opening through which illumination light emitted from the light source can pass is formed at a position off-centered from the optical axis. The light condensing member is arranged between the light source and the iris diaphragm. The slit can be arranged at a position that is substantially optically conjugated with the fundus of an eye to be examined, in which a slit-like opening through which illumination light has passed through the opening can pass is formed. The image sensor receives return-light from the fundus irradiated with the illumination light that has passed through the slit.

摘要： The slit lamp microscope according to an exemplary embodiment comprises a scanning unit and a data processing unit. The scanning unit scans an anterior segment of an eye under examination with slit light to collect a plurality of sectional images. The data processing unit generates cloudiness distribution information which shows the distribution of clouded parts in the lens of the eye under examination on the basis of the plurality of sectional images collected by the scanning unit.

摘要： A slit lamp microscope according to an exemplary embodiment comprises an illumination system, an imaging system, and a movement mechanism. The illumination system emits slit light to the anterior segment of an eye being examined. The imaging system comprises: an optical system that guides light from the anterior segment which is being irradiated with the slit light; and an imaging element that receives the light guided by the optical system on an imaging plane. The movement mechanism moves the illumination system and the imaging system. An object plane along the optical axis of the illumination system and the imaging plane of the optical system satisfy the Scheimpflug principle. The imaging system repeatedly images the anterior eye segment to acquire a plurality of images thereof while the illumination system and imaging system are moved by the movement mechanism.

摘要： An ophthalmic system of an embodiment includes a slit lamp microscope and an information processing apparatus. The slit lamp microscope includes an image acquisition device that acquires a three dimensional image by photographing a subject's eye, and a first communication device that transmits the three dimensional image to the information processing apparatus. The information processing apparatus includes a second communication device that receives the three dimensional image transmitted by the first communication device, a display controller that displays a first image based on the three dimensional image on a display device, a partial region designation processor that designates a partial region of the first image, and a rendering processor that renders the three dimensional image based on the partial region to construct a second image. The display controller displays the second image on the display device.
