Abstract
For the past three decades, fluorescein angiography has proved to be extremely valuable in expanding our knowledge of pathologic anatomy and pathophysiology of various conditions and has aided the diagnosis and monitoring of treatment of retinal vascular and macular diseases. Photographic examination of the fiLndus oculi allowed measurements of two dimensions; length and breadth. The advent of fluorescein angiography introduced a third dimension, the time dimension, which makes possible measurement of local circulation time and comparison of dye appearance times in different vessels. Fluorescein angiography also provides better visualization due to better contrast, black and white.
Fluorescein angiography of the retina is of great value not only for ophthalmologist but also for medical science as a whole, so it offers an opportunity to investigate and record both function and structure of the living eye. It allows one to study the blood tiow in retinal vessels and the distribution of these vessels, and gives evidence of underlying disease in the pathological conditions.
Schatz (1989) stated that any ophthalmologist who sees patients with retinal problems must understand fluorescein angiography, and those who treat patients with retinal vascular and macular diseases must be able to interpret fluorescein angiograms.
The aim of this work is to outline the role of fluorescein angiography of the macWa in the diagnosis and prognosis of common retinal vascular disorders; diabetic retinopathy, retinal venous occlusion, retinal arterial obstruction, hypertensive retinopathy and renal retinopathy. In an attempt to show an interpret specific findings that might facilitate early diagnosis of doubtthl cases, the cause of vision loss and prediction of the disease progress to help in its management.
