Clinical Experience with Fluorescence Retinal Cinematography

Abstract

Clinical experience with fluorescence retinal cinematography in 70 patients is presented. The sequence of normal retinal vascular filling is described. Of particular interest is the demonstration that the retinal circulation consists of a number of vascular segments, each of which may have different flow characteristics. The pathologic alterations in patients with diabetic and hypertensive retinopathy, papilledema, and other disease states are discussed. The dynamic portrayal of the retinal circulation, enabling moment-to-moment evaluation, and the efficiency of the cinematographic technic are distinct advantages over the singlefilm method.

Fundus Photography: Some Evolutionary Perspectives and Some Methods of the ZEISS FUNDUS CAMERA

“…Table 1 clearly shows that for a wide range of internal eye diseases the fluorescein angiogram is a sensitive tool for early detection and reliable diagnosis. The condition of retinal circulation may be more critically evaluated with movie photography of fluorescein angiograms which enable the clinician to observe the anomaly as a sequence of events as recognised by Linhart et a/ (1964) with their 10 to 16 frames per second technique. The physiological baselines of retinal circulation time may be better defined by replaying the 20 frames per second fluorescein cinephotography in slow motion (Evans and Wruck 1971).…”
