Visual loss in nonarteritic AION is typically maximal at onset. In a subset of patients with AION, however, visual loss progresses during the first 4 weeks.¹ In giant cell arteritis, visual loss may be due to AION or posterior ischemic optic neuropathy in which the optic disc is not swollen. Both conditions may progress rapidly, even to no light perception, in a matter of hours or days. Malignant or aggressive gliomas of the optic nerve are lesions that initially may be confused with nonarteritic AION or arteritic AION because they may have a similar clinical picture of deteriorating vision and a swollen optic disc.
