Advanced Techniques for Fluorescein Angiography

Abstract

THE USE of fluorescent angiophotography is becoming increasingly widespread in the investigation of both clinical and research problems. It is therefore pertinent to reevaluate and improve existing technical methods in order to obtain better results. The purpose of this paper is to describe the modifications of the fundus camera (Zeiss) for rapid serial photography and to discuss the use of an improved filter system and a new mechanical injection system. The utilization of the phenomenon of fluorescent emission in fluorescein angiography of human ocular tissues presents many technical difficulties.¹ There is, in addition, the problem of ensuring the safety and reliability which is essential to any clinical procedure. The method to be described is presented as one which shows technical improvement without detriment to the well being of the patient.
