Neurovascular compression causing optic neuropathy is rare but potentially treatable. This report discusses a case of optic nerve compression within the orbital apex due to an ectatic internal carotid artery in a patient with congenital absence of the contralateral internal carotid artery, highlighting the complementary roles of advanced neuroimaging and neuro-ophthalmologic examination in diagnosis.
Neurovascular compression is a rare but potentially treatable cause of optic neuropathy. Although incidental contact of the cisternal optic nerve and internal carotid artery (ICA) is common, compressive optic neuropathy occurring within the orbital apex has not been comprehensively described. We report a case of intra-orbital and intracanalicular optic nerve compression due to an ectatic ICA in a patient with congenital absence of the contralateral ICA. This report describes the complementary roles of advanced neuroimaging and neuro-ophthalmologic examination in rendering the diagnosis. (C) 2020 by North American Neuro-Ophthalmology Society
