Abstract
Idiopathic intracranial hypertension, a syndrome of obscure origin, occurs particularly in fat adolescent girls and young women. The usual symptoms are headache, blurred vision, a vague dizziness, horizontal diplopia and transient visual obscurations etc., and ophthalmoscopic examination reveals papillederma, due to increased ICP. Visual field testing usually shows slight peripheral constrictions with enlargement of the blind sports. CSF pressure is elevated in the range of 250 to 450 mm of water. Radiological or the other laboratory tests show no specific abnormalities. Treatment for idiopathic intracranial hypertension is focused on early detection and prevention of vision loss, the only permanent morbidity. Many different modes of medical treatment, including weight reduction, repeated lumber puncture, corticosteroids, diuretics, glycerol or carbonic anhydrase inhibitors, have successfully been tried up to 90% of the patients. In the remaining patients, particularly in those with measurable impairment of vision that does not respond to conventinal medical therapies, surgical procedure should be considered. We report a case of idiopathic intracranial hypertension successfully treated with optic nerve sheath fenestration.
