A slitlamp comparator system for macular photocoagulation.
A slitlamp comparator device has been developed to project the image of a 35mm angiogram frame into the field of view of a standard slitlamp during macular photocoagulation. The image may be varied in brightness, magnification, and position, and viewed either on a black background or superimposed on a slitlamp fundus image. The comparator is a useful alternative to conventional angiogram projection systems and suggests the utility of more sophisticated "heads-up" display devices.
