  • Publication number: 20070052927
    Abstract: A simulation image of an index image formed on a fundus of an eye to be examined when each of a plurality of indices is presented to the eye to be examined is generated based on optical characteristic data of the eye to be examined and image data of the indices associated with respective spatial frequencies. Of the generated simulation images, simulation images whose contrasts can be recognized by the eye to be examined are selected at each of the spatial frequencies. Of the selected simulation images, a simulation image in which a contrast of an index being a basis for the simulation image is minimum is specified. Mark information for marking index information of indices which are the bases for simulation images specified at each of the spatial frequencies are added to image data of an examination sheet and displayed thereon.

  • Patent number: 6869428
    Abstract: An ophthalmologic photocoagulator and photoagulation method thereof in which visibility of sighting laser beam which is projected onto the eye fundus of an eye to be examined is improved and a loss in the amount of treatment laser beam can be reduced. The ophthalmologic photocoagulator includes: a treatment laser oscillator that oscillates a treatment laser beam for conducting treatment on a diseased part of the eye to be examined by photocoagulation; a sighting laser oscillator that oscillates a sighting laser beam for conducting sighting on the diseased part of the eye to be examined which is to be irradiated with the treatment laser beam; and a polarization beam splitter for combining an optical path of the treatment laser beam with an optical path of the sighting laser beam by polarization coupling. The treatment laser beam oscillating from the treatment laser oscillator and the sighting laser beam oscillating from the sighting laser oscillator have similar colors.
