Atypical progression of visual loss in a patient with primary open-angle glaucoma

DOI: 10.5935/0034-7280.20140009

Dolichoectasia of the internal carotid artery (ICA) is a rare condition that may be associated with neuro-ophthalmic manifestations, such as loss of visual acuity and visual field resulting from compression of the optic nerve (ON). The aim is to report a 67-year-old male patient with primary open-angle glaucoma (POAG) with atypical evolution, asymmetry of cupping and increased pallor of the rim of the left ON, due to compressive optic neuropathy by the dolichoectatic segment. The diagnosis was based on clinical history, appearance of the ON and neuroimaging.
