Ischemic optic neuropathy
by Alike Medical Team ∙ Updated on June 13, 2023
General
Ischemic optic neuropathy (ION) refers to a condition which is characterized by a sudden loss of vision due to lack of blood flow to the optic nerve. It happens more commonly unilaterally, and may affect either the central or peripheral vision. Damage to the optic nerve cannot be fixed, thus causing permanent vision loss. ION may be a complication of temporal arteritis.
