Fluorescein studies in retinal vascular occlusion.

THE clinical entities of retinal artery occlusion and retinal vein thrombosis produce dis- turbances in vision resulting directly from interference with the retinal circulation. The introduction of fluorescence retinal photography (Novotny and Alvis, 1961) and subsequent technical modifications provide a useful tool for investigating the extent of the circulatory disturbance in these vascular occlusions and correlating it with the clinical signs. This paper reports the results of 39 examinations carried out on patients as soon after diagnosis as possible.
