Ophthalmic system, ophthalmic information processing apparatus, and ophthalmic information processing method

An ophthalmic information processing apparatus comprising:

• a communication device that receives, via a communication path, a three dimensional image acquired by photographing a subject's eye with a slit lamp microscope and an image acquisition 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;
• 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
• the image acquisition device includes
• an illumination system that illuminates the subject's eye with slit light,
• an imaging system that guides returning light of the slit light from the subject's eye to an imaging device, and
• a movement device that moves at least one of the illumination system and the imaging system;
• the image acquisition device further includes a focal position changer for changing at least one of a focal position of the illumination system and a focal position of the imaging system;
• and
• the ophthalmic system further includes a three dimensional image construction processor that constructs a three dimensional image based on a plurality of cross sectional images acquired by the imaging device in parallel with both movement of the at least one of the illumination system and the imaging system and change in the at least one of the focal position of the illumination system and the focal position of the imaging system.

A method of processing ophthalmic information executed by an ophthalmic system comprising a slit lamp microscope and an information processing apparatus connected to the slit lamp microscope via a communication path, the method comprising:

• acquiring a three dimensional image by photographing a subject's eye with the slit lamp microscope;
• transmitting the three dimensional image from the slit lamp microscope to the information processing apparatus;
• receiving the three dimensional image with the information processing apparatus;
• displaying a first image based on the three dimensional image on a display device;
• designating a partial region of the first image;
• constructing a second image by rendering the three dimensional image based on the partial region;
• displaying the second image on the display device;
• illuminating the subject's eye with slit light by an illumination system;
• guiding returning light of the slit light from the subject's eye to an imaging device having an imaging system;
• moving at least one of the illumination system and the imaging system;
• changing at least one of a focal position of the illumination system and a focal position of the imaging system;
• and
• constructing a three dimensional image based on a plurality of cross sectional images acquired by the imaging device in parallel with both the moving of the at least one of the illumination system and the imaging system and the changing of the at least one of the focal position of the illumination system and the focal position of the imaging system.
