CINEMATOGRAPHY OF HUMAN RETINAL VESSELS

CINEMATOGRAPHY OF HUMAN RETINAL VESSELS In recent years, functional changes in the retinal vessels and other structures of the fundus have become increasingly important to clinicians and others. Changes not readily discernible with ophthalmoscopy or serial still photography can be demonstrated by a practical technique of cinematography designed and in use at the University of Oregon Medical School. With a special camera, variations in amplitude, character, and rhythm of pulsation of the retinal arterial system can be detected for research and teaching purposes, and to aid in differential diagnosis, or to permit early evaluation of therapy. The camera contains three basic units: a mounted +20 D. condensing lens, a light source with means of changing magnification, and the camera body containing film and a continuous focusing device. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png JAMA American Medical Association

Abstract

In recent years, functional changes in the retinal vessels and other structures of the fundus have become increasingly important to clinicians and others. Changes not readily discernible with ophthalmoscopy or serial still photography can be demonstrated by a practical technique of cinematography designed and in use at the University of Oregon Medical School. With a special camera, variations in amplitude, character, and rhythm of pulsation of the retinal arterial system can be detected for research and teaching purposes, and to aid in differential diagnosis, or to permit early evaluation of therapy. The camera contains three basic units: a mounted +20 D. condensing lens, a light source with means of changing magnification, and the camera body containing film and a continuous focusing device.
