Slit-lamp microscope and ophthalmic system

An ophthalmic system comprising a slit lamp microscope and an information processing apparatus connected via a communication path, wherein

• the slit lamp microscope includes:
• an illumination system including an illumination light source and configured to project slit light onto an anterior segment of a subject's eye from a first direction;
• a first photographing system including a lens and configured to photograph the anterior segment onto which the slit light is being projected, from a second direction different from the first direction;
• a second photographing system configured to photograph the anterior segment;
• a fixation system including a fixation light source and configured to output fixation light for fixation of the subject's eye;
• a movement mechanism including an actuator and configured to be capable of moving the illumination system and the first photographing system;
• a controller circuit configured to perform a first control for the movement mechanism to move at least the illumination system, 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, and a third control for the second photographing system to photograph the anterior segment a plurality of times in parallel with the first control and the second control;
• and
• a transmitter configured to transmit a plurality of images acquired by the first photographing system under the second control to the information processing apparatus via the communication path, and
• the information processing apparatus includes:
• a receiver configured to receive the plurality of images transmitted by the transmitter, and
• a three dimensional image construction circuit configured to construct a three dimensional image based on the plurality of images received by the receiver.
