A close-up imaging device that generates slit light on the basis of light-source light emitted from a light source built into a mobile communication terminal device. The close-up imaging device is mounted onto the mobile communication terminal device, and a moving image of the tissue to be observed of the examined eye is captured by a camera module built into the mobile communication terminal device. Then, in a diagnosis support server device, a diagnosable frame image included in the captured moving image is extracted, at least one of a heath state of the examined eye and any one or more of a distance, an angle, and an area in some tissue of the examined eye is estimated on the basis of the diagnosable frame image extracted, and diagnosis support information is generated and distributed to the corresponding mobile communication terminal device.

The ophthalmologic microscope has an illumination device for projecting light onto an eye to be observed and a microscope device with a camera to view the eye. The illumination device generates pulsed light and is slaved to the frame rate of the camera, which allows to run the camera in free-running mode for achieving a high frame rate. The light is pulsed at least at twice the frame rate of the camera to reduce flicker. The illumination device uses an array of micro-mirrors as spatial light modulator, and the mirrors are controlled for a balanced deflection over the frame cycles.

A slit lamp microscope according to an embodiment of the present technology includes an illumination optical system, an imaging optical system, and a display unit. The illumination optical system emits slit light toward an eye to be examined. The imaging optical system images light reflected by the eye to be examined. The display unit has a display surface that displays a captured image obtained by imaging the eye to be examined, in which a relationship that a direction perpendicular to the display surface is parallel to a predetermined surface direction including an imaging direction of the imaging optical system is maintained. Accordingly, a novel operation can be performed.

In certain embodiments, an ophthalmic surgical system for viewing an eye includes an ophthalmic microscope and a laser device. The ophthalmic microscope receives light reflected or scattered backwards from within the vitreous of the eye in order to provide an image of an object within the vitreous. The ophthalmic microscope includes a slit illumination source (which includes a light source and an optical element), a spectral filter, and oculars. The slit illumination source illuminates the eye with light, where the light source provides the light, and the optical element directs the light into the eye. The spectral filter filters out red spectral components of the light. The oculars receive the light from the eye in order to provide the image of the object. The laser device generates a laser beam to direct towards the object within the eye.

In certain embodiments, an ophthalmic system for visualizing an interior of an eye includes an illumination system and a visualization system. The illumination system illuminates the interior of the eye. The illumination system includes an annular illuminator that directs annular illumination, which has an illumination axis, towards the interior of the eye. The visualization system provides an image of the interior of the eye. The visualization system comprises visualization optical elements, which include an objective lens and oculars. The objective lens receives light reflected from the interior of the eye. The oculars, which have an ocular axis, transmit the reflected light to yield an image of the interior of the eye. In other embodiments, the illumination system comprises a multi-beam illuminator that directs multiple illumination beams towards the interior of the eye.
