Permanent visual impairment in childhood pseudotumor cerebri.

Contrary to statements in the literature, youth does not seem to confer protection from visual loss in pseudotumor cerebri. We examined five children and adolescents who suffered permanent loss of visual acuity or field in association with this disorder. All of them had impairment at the time of diagnosis, and two of the five developed further visual failure while under observation. Children and adolescents with pseudotumor should be kept under the same close ophthalmic surveillance as has been advocated for adults with this disease.
