1. An optical treatment device, comprising:
a treatment beam generation unit that generates a treatment beam;
a beam delivery unit that forms a path along which the treatment beam radiates to a treatment area of a patient; and
a monitoring unit that radiates a detecting beam to the treatment area and that detects state information of the treatment area based on interference information of the detecting beam scattered or reflected from the treatment area,
wherein, while the treatment beam is radiated to one treatment position, the monitoring unit radiates the detecting beam multiple times to the treatment position to detect state information of the treatment position, and
wherein the monitoring unit compares state information detected by each detecting beam with state information detected by the previously radiated detecting beam to determine a state change of the treatment area.
