Videofluoroscopy in macular disease

Fluorescein Angiography has contributed immensely to our understanding and management of macular disease. Ridley first introduced the concept of television ophthalmoscopy and in 1973 Van Heuven and Schaffer reported the value of videofluoroscopy using a low light level system and an image intensifier. Major advances in electronic imaging technology since then have permitted high quality videofluoroscopy to be developed in particular the integral silicone intensified tube (SIT) allowed ultra low light levels to be recorded. A videofluorography system has been in routine use in our department for the last six years and we have found it to have certain advantages over conventional photography in macular disease. In this presentation we demonstrate some of these.
