Binasal hemianopia due to bilateral internal carotid artery atherosclerosis

Binasal Hemianopia Due to Bilateral Internal Carotid Arteries Dolichoectasia: A Case Report and Literature Review

“…Isolated binasal hemianopia is exceptionally uncommon. Various causes of ocular or neurological conditions have been reported and found to be commonly associated with ocular pathology (Hamann et al, 2015). Ashwin and Quinlan (2006) reported an incidental finding of binasal hemianopia caused by keratoconus.…”

“…The first documented report in 1912 reported that binasal hemianopia was found in a patient with a brain tumour (Cushing & Walker, 1915). Intracranial congenital anomalies, hydrocephalus, intracranial mass lesions, pneumosinus dilatans of sphenoid sinus, neurosyphilis and vascular causes such as pituitary apoplexy and internal carotid artery atherosclerosis were among the reported causes for binasal hemianopia (Bryan et al, 2014;Hamann et al, 2015;Kawahigashi & Nishiguchi, 2018;Kim & Kim, 2019;Lestak et al, 2011;Pringle et al, 2004;Salinas Garcia & Smith, 1978).…”

“…This occur before the advent of advanced radiological imaging such as CT or MRI scans (Knapp, 1932;Smith, 1905). Table 1 summarizes reported cases of binasal hemianopia due to intracranial vascular pathologies, demonstrating the scarcity of reports on binasal hemianopia visual field defects caused by vascular pathologies (Hamann et al, 2015;Kawahigashi & Nishiguchi, 2018;Rebolleda et al, 2015).…”

False Positive Hemianopia

“…Retinal diseases, including retinitis pigmentosa sine pigmento [1] or corneal pathology as keratoconus [3], have also described as possible causes of binasal defect. In rare cases, binasal hemianopia has been attributed to neurological etiologies, including bilateral internal carotid artery aneurysms or atherosclerosis [4], hydrocephalus [5], olfactory groove meningioma [5], intracranial mass lesions, and pituitary apoplexy [1]. Pringle et al [6] reported a case of progressive binasal visual field loss due to neurosyphilis.…”

Idiopathic binasal hemianopia: case report and literature review

“…Bilateral internal carotid artery atherosclerosis has been recognized as a cause of binasal field defect. 8 Calcifications and slight dolichoectasia of both internal carotid arteries adjacent to the optic nerves may damage temporal fibers thus producing a corresponding nasal field defect bilaterally. Aneurysms of the internal carotid arteries simultaneously compressing the adjacent non-crossing fibers of both optic nerves are also able to produce a binasal hemianopia.…”
