Idiopathic Intracranial Hypertension (IIH) is mainly a disease affecting women of child bearing age. It is characterized by increased intracranial pressure in the absence of any tumor or other structural brain abnormality. The main symptoms include headache, blurring of vision, diplopia and pulsatile tinnitus. This condition has a strong correlation with obesity. It is diagnosed in accordance with Modified Dandy’s Criteria which include signs and symptoms of raised intracranial pressure, absence of localizing signs on neurological examination except lateral rectus palsy, absence of structural abnormality on brain imaging, absence of CSF abnormalities except raised opening pressure and awake and alert patient. Fundus abnormalities include papilloedema of varying grades. To date, there has been no study to correlate opening pressure on lumbar puncture with fundus abnormalities. This study was done to correlate grades of papilloedema with opening pressures on lumbar puncture study and thus to estimate prognosis in these patients.
