Neuro-ophthalmology is a crossing discipline. Optic neuritis and ischemic optic neuropathy are the hot points of this field. Currently, studies of optic neuritis epidemiology, etiology and clinical features have already been done in china. And the expert consensus of optic neuritis therapy was published. The pathogenesis and treatment of ischemic optic neuropathy is another hot point. We have embarked on the epidemiological study of ischemic optic neuropathy in china. We also appeal the ophthalmologists to pay more attention on the therapy of posterior visual pathway.
