According to one embodiment, a laser treatment apparatus is configured to apply laser treatment to a patients eye, and includes an irradiation system, an illumination system, an imaging system, an image acquisition unit, and a composite image presenting unit. The irradiation system irradiates the patients eye with laser beams emitted from a light source. The illumination system illuminates the patients eye with slit light. The imaging system guides the slit light returning from the patients eye to an imaging device. The image acquisition unit acquires a first image that represents a region of the patients eye including the illumination field of the slit light. The composite image presenting unit presents a composite image of the first image acquired by the image acquisition unit and a second image of the patients eye based on output of the imaging device.
