A laser treatment apparatus providing a slit-lamp microscope with which an eye of a patient is observed, a box unit which is provided with an optical system to deliver a laser beam inside an observing visual field of the slit-lamp microscope, an attachable device which mounts the box unit on the slit-lamp microscope, and an optical fiber through which a laser beam for ophthalmic treatment is delivered to the box unit, wherein the box unit is provided with a dichroic mirror having characteristics of reflecting the laser beam for treatment to the patient's eye while absorbing a therapeutic surgery laser beam being incident to the dichroic mirror.

Laser treatment apparatus

Ophthalmic photographing an image of an eye to be examined comprises: frame memory for memorizing the image data of the photographed eye, light detecting device for detecting an amount of the light emitted from a light source for photographing, correcting device for correcting a density of the image data memorized in the frame memory by comparing the amount of the light detected by the light detecting device with predetermined amount of reference light. Therefore the ophthalmic photographing apparatus can display the image having a constant density, even though the amount of the light emitted from the light source for photographing changes.
