The present invention relates to an optical treatment apparatus and an operating method thereof. The present invention provides an optical treatment apparatus and an operating method thereof, the optical treatment apparatus comprising: a treatment beam generation unit for generating a treatment beam a beam delivery unit for forming a path through which the treatment beam generated from the treatment beam generation unit travels to a treatment area located in a fundus a monitoring unit for irradiating a detecting beam along the path through which the treatment beam travels, and detecting state information on the treatment area on the basis of speckle change information of the detecting beam scattered and reflected from the treatment area and a control unit for controlling the driving of the treatment beam generation unit on the basis of the state information on the treatment area detected by the monitoring unit.
