Ischemic optic neuropathy in chronic papilledema
G. J. Green, S. Lessell and J. I. Loewenstein
We evaluated the condition of a patient with chronic papilledema due to
pseudotumor cerebri in whom a permanent, monocular, inferior, altitudinal,
visual field defect suddenly developed. Clinical and fluorescein
angiographic findings indicated that the loss of visual field was due to
ischemic optic neuropathy. Ischemic optic neuropathy might occur in
papilledema if the tissue pressure in the optic disc becomes sufficiently
elevated to occlude the pressure-sensitive prelaminar arterioles.
