Abstract

An arcuate visual field defect connecting to the blind spot indicates that the lesion results from the damage to the nerve fiber bundle extending from the optic disc. How can we determine whether this damage is the manifestation of the acute phase of ischemic optic neuropathy (ION) or normal tension glaucoma (NTG)? This section focuses on the similarities and differences between the two diseases in terms of pathogenesis, as well as the key points of clinical differentiation.
