Idiopathic intracranial hypertension is defined as signs and symptoms caused only by raised intracranial pressure without established brain pathogenesis.IIH is typically seen in women who are obese and of childbearing age.The pathogenic mechanisms of IIH are still unclear,but the unbalance between production and absorption of cerebral spinal fluid was speculated.The clinical symptoms include headache,transient visual obscuration,pulsation tinnitus,and diplopia.Most patients present to ophthalmologist as bilateral papilledema,whereas underdiagnosed or inappropriate management can lead to severe optic atrophy and permanent visual loss.Management includes disease modification as body weight loss,medication treatment as inhibitor of carbonic anhydrase enzyme,surgical interventions as optic nerve sheath fenestration,venous sinus stenting and CSF diversion.In this review,we focus on the epidemiology feature,clinical manifestations,diagnosed criteria,as well as the characteristic of IIH patients in China.As IIH is not widely understood by ophthalmologist and neurologist in China,we addressed that the prompt diagnosis and treatment can avoid the severe visual loss in patient of late stage IIH.
