Abstract :

Introduction: Idiopathic intracranial hypertension (IIH) is a disorder of elevated cereospinal fluid pressure of unknown cause. It is usually seen in women of childbeå age. Patients and methods:This was a prospective study conducted over a period of one year from Feuary 2017 to March 2018 and followed up for mean of 12 months till March 2019 . All patients with IIH who met the modified dandy criteria were reviewed and relevant data was collected like age, sex, BMI, presenting symptoms, systemic history(medical and surgical), drug history, imaging studies, treatment and outcome. Results: 30 patients were included in the study. Systemic risk factors were noted in 6 patients Headache associated with nausea was the most common complaint followed by blurring of vision and diplopia. A high BMI was seen in 19 out of 30 patients (highest BMI – 29.8). OCP usage was seen in 5 patients. MRI findings consistent with IIH was seen in all patients . CSF analysis revealed elevated opening pressure(> 250 mm water) in all, with normal biochemical studies. All patients were managed with medicines(93%) and surgery was reserved for those refractory to medical management(6.66%). Conclusions: Idiopathic intracranial hypertension is characterized by elevated CSF pressure of unknown cause mainly seen in women of child beå age. Diagnosis should adhere to the modified Dandy’s criteria. These patients should be followed closely and monitored for therapeutic response and detoriation of vision. Treatment is always started medically and followed up surgical when not controlled.
