Abstract
A photocoagulation apparatus for coagulating an affected part of a patient by irradiating the part with a treatment laser beam emitted from a laser oscillator (10) is disclosed. The apparatus includes an input section (3) for setting an irradiation condition of the treatment laser beam, a detecting section (27, 40-43, 46, 47, 51) for optically detecting a coagulating state of a coagulation part produced by irradiation of the treatment beam, an analysis section (51) for analyzing the coagulating state detected by the detection section as compared with a desired coagulating state to be produced by irradiation of the treatment laser beam under the irradiation condition set with the input section, and a control section (50) for instructing a change in the irradiation condition as needed based on a result of analysis by the analysis section.
