[Unilateral papilledema in pseudotumor cerebri]

The appearance of unilateral papilledema in the fundus photos of 6 women with pseudotumor cerebri is presented. Associated findings included obesity in 5 and a partially empty sella in 2. The possible explanations for the development of unilateral papilledema in pseudotumor cerebri are reviewed and favor a mechanism that is present at the distal end of the optic nerves.
