ABSTRACT:
An apparatus for clogging blood vessels of an eye fundus includes an illuminating optical system (1) for illuminating an eye fundus of a subject, who has been given an injection of an infrared fluorescent agent, with infrared rays of light and exciting the infrared fluorescent agent so as to generate infrared fluorescence, a photographic optical system (2) for observing and photographing the eye fundus, and a projecting optical system (21) for projecting a laser beam of light having a specific wavelength onto the subject who has been also given an injection of a photosensitive substance which undergoes a photochemical change by the laser beam. In the apparatus, while a region which emits infrared fluorescence is being observed, the laser beam is projected onto the photosensitive substance so as to clog blood vessels of a diseased part in the depth of the eye fundus.
