Integrated projection of fundus photographs during macular photocoagulation

M. W. Gaynon

Macular photocoagulation requires precise localization of abnormalities to be treated, in order to accomplish the aims of therapy without unnecessarily damaging adjacent tissue. A method is described by which a color fundus photo or a fluorescein image can be projected through a beam splitter into the ocular of a laser slit lamp, thus affording an image congruent with the surgeon's view of the patient's macula.
