Claim Text:
1. A slit lamp microscope, comprising: an illumination system configured to include: a light source that outputs illumination light; a slit forming part that forms a slit capable of changing the slit width; a diffusion member that is capable of inserting into and removed from a light path of the illumination light and diffuses the illumination light; and a filter that is capable of inserting into and removed from the light path, wherein the illumination light having passed through the slit is irradiated to an eye and the amount as well as the irradiation angle of the illumination light are changeable, a background illumination system configured to irradiate background illumination light to a peripheral region of an irradiation field of the illumination light; an observation system configured to include a magnification optical system for changing observation magnification, and guide reflected light of the illumination light from the eye to each of an image sensor and an eyepiece; a display; a storage configured to store correspondence information that associates, with each of multiple sites of an eye, standard setting conditions regarding at least one of: a value of the observation magnification; a value of the slit width; a value of the light amount of the illumination light; a value of the irradiation angle; the presence or absence of irradiation of the background illumination light; the presence or absence of the diffusion member in the light path; and the presence or absence of the filter in the light path; a designating part configured to designate a site of the eye; a searching part configured to search the standard setting conditions corresponding to the designated site from the correspondence information; an acquiring part configured to acquire current setting states regarding at least one of: a value of the observation magnification; a value of the slit width; a value of the light amount of the illumination light; a value of the irradiation angle; the presence or absence of irradiation of the background illumination light; the presence or absence of the diffusion member in the light path; and the presence or absence of the filter in the light path; a specifying part configured to specify, from among the acquired current setting states, those differing from the searched standard setting conditions; and a controller configured to display information based on the specified result by the specifying part on the display.
