Abstract: An ophthalmologic apparatus includes an illumination system that is supported to be rotatable about a subject's eye with an irradiation direction of illumination light kept toward the subject's eye and an observation system that has a camera device and is arranged opposite to a position of the subject's eye across the illumination system. The camera device includes an imaging unit that receives reflection of the illumination light from the subject's eye and a light emitting unit for background illumination that is provided in the observation system and located below the subject's eye.

Abstract: A slit lamp microscope of an aspect example includes an illumination system, first photographing system, fixation system, movement mechanism, and controller. The illumination system projects slit light onto an anterior segment of a subject's eye from a first direction. The first photographing system photographs the anterior segment onto which the slit light is being projected, from a second direction different from the first direction. The fixation system outputs fixation light for fixation of the subject's eye. The movement mechanism moves the illumination system and the first photographing system, the controller performs a first control for the movement mechanism to move at least the illumination system and a second control for the first photographing system to photograph the anterior segment a plurality of times in parallel with each other while causing the fixation system to output the fixation light.

Abstract: A slit-lamp microscope includes an illumination system that is configured to project a slit light onto a subject eye; a slit portion that is configured to generate the slit light having a width by passing a light from a light source through a slit between a pair of slit blades in the illumination system; and a controller that is configured to control the light source, wherein the controller is configured to turn the light source off when the pair of slit blades is closed.

Abstract: A slit lamp microscope of some embodiment examples includes an illumination system, first photographing system, first movement mechanism, and controller. The illumination system includes a slit forming unit that forms a slit for generating slit light and projects the slit light onto an anterior segment of a subject's eye from a first direction. The first photographing system photographs the anterior segment onto which the slit light is being projected, from a second direction different from the first direction. The first movement mechanism moves a movable portion that includes at least the slit forming unit. The controller performs a first control for the first movement mechanism to move the movable portion and a second control for the first photographing system to photograph the anterior segment a plurality of times in parallel with each other.
