Anterior ischemic optic neuropathies (AAION) case showed a marked involvement of optic nerve head (A), with a strong damage of retinal nerve fiber layer (RNFL) (B), together with sectorial optical coherence tomography angiography (OCTA) perfusion impairment (C) and superior visual field defects (D).
