[Advances in application of non-invasive ophthalmologic technologies in idiopathic intracranial hypertension]

Idiopathic intracranial hypertension (IIH) is a common neuro-ophthalmologic disorder which leads to significant visual impairment. Clinically, visual manifestation secondary to increased intracranial hypertension generally shows papilledema and the progressive visual impairment subsequently. IIH is a diagnosis of exclusion. The methods include lumber puncture (LP), laboratory tests and imaging examination. However, those methods do limit in evaluation and follow-up in IIH. Currently, with the development of diagnostic technology in ophthalmology, Optical Coherence Tomography and B-scan ultrasound have been employed to estimate intracranial hypertension not only in early diagnosis, but also in long-term follow-up examination. The goal of this review is to sumarize the value of various ophthalmologic methods in evaluation and management of IIH.
