Studies of the Findings o Fluorescein Retinoangiographic Pictures of Papilledema in the Brain Tumor

ABSTRACT

Fluorescein retinal angography has been used in order to make differential diagnosis between true papilledema and pseudopapilledema, and to make early confirmation of the incipient papilledema. 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 filterKodak Wratten 47 A, barrier filterSchott 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 fluorescen is seen in the patients of the 3 rd ventricular or posterior fossa tumors. 3. The decreased visual acuity is prominent in the patients showing marked capillary dilatation and microaneurysm.
