Abstract
|
|
|
Fluorescein retinal angiography has been used in order to make differential diagnosis between true papilledenta and pseudopapilledema, and to make early confirmation of the incipient papill edema.
After injection of 5 cc of 10 fluorescein sodium into antecubital vein, the fluorescein retinal angiographic findings of 6 normal adults and 17 papilledematous patients. of the. brain tumor, .were obtained by Zeiss fundus camera (exciter filter: Kodak´ Wratten 47 A, barrier filter: Schott GG 14).
1. The characteristic findings of papilledema in the disc are:
a. Leakage of fluorescein from capillaries and persistence of the fluorescence till late stage.
b. Capillary dilatation.
c. Microaneurysm.
2. The massive leakage of the fluorescein is. seen in the patients of the 3rd ventricular or posterior fossa tumor.
3. The decreased visual acuity is prominent in the patients showing marked capillary dilatation and microaneurysm.
