title: Video and digital fluorescein angiography.
abstract: A video recording system, which provides real-time imaging and instant reporting of retinal fluorescein angiograms, with improved patient comfort, is described. Digital image-processing methods can be applied to video angiograms to improve image quality, quantitate retinal blood flow, measure areas, improve storage and access, and send images via phone lines or other electronic communication channels. Video image quality is somewhat inferior to conventional photographic techniques, but is more than adequate for diagnostic interpretation.
