ABSTRACT

Purpose: To evaluate the demographic characteristics, symptoms of presentation, clinical evolution, treatment and prognosis of the patients with pseudotumor cerebri or idiopathic intracranial hypertension.
Methods: A cohort study of cases with pseudotumor cerebri was performed from 1991 to 2001, in the Neuroophthalmology Service of the «Instituto Nacional de Neurología y Neurocirgía». All the patients had a follow up of al least 10 months. A correlation of the neuro-ophthalmologic exploration at the beginning of the diagnosis and last follow up was performed.
Results: 68 patients were included, 83.8% were women with overload. The visual sharpness at initial consultation was affected severely in the 10.3% of the cases and 7.3 % in the last follow up. The visual field alterations improved significantly. The VI cranial nerve was affected transitorily in 14.7%. The treatments used were acetazolamide in 98%, optic nerve sheath fenestration in 11% and ventriculoperitoneal or lumboperitoneal derivation in 20%.
Conclusions: Pseudotumor cerebri is not always a benign illness and the diagnosis is delayed in 20% of the cases. Macular edema is a frequent cause of low vision. Most of the patients respond to acetazolamide. The surgical procedures should be reserved to the cases that do not respond to the medical treatment.
