Occipital Infarction With Hemianopsia From Carotid Occlusive Disease Michael S. Pessin, MD, Eddie S. Kwan, MD, R. Michael Scott, MD, and Thomas R. Hedges III, MD Extracranial internal carotid artery occlusive disease usually produces stroke in the middle cerebral artery territory or the border zone between the middle and anterior cerebral arteries.

Occipital lobe ischemia may result from 1) dislodg-ment of atheromatous material, 2) embolization of thrombus from the catheter tip, 3) in situ thrombosis or spasm of cerebral vessels, 4) a hypotensive episode, 5) preexisting hypertensive disease or migraine head-aches, or 6) selective vulnerability of occipital lobes to

The occipital lobe, the final type of cortical stroke, plays a large role in your vision. As a result, and occipital lobe stroke often results in vision difficulties like central vision loss, cortical blindness, visual hallucinations, or other secondary effects.

Recurrent Bilateral Occipital Infarct with Cortical Blindness and Anton Syndrome KiuKwongYew,1 SanihahAbdulhalim,2 AhmadTajudinLiza-Sharmini,1 andJohnTharakan3 1DepartmentofOphthalmology,SchoolofMedicalSciences,UniversitiSainsMalaysia,HealthCampus, 16150KubangKerian,Kelantan,Malaysia

Each area in the brain controls different functions or skills. Cortical blindness is indicative of bilateral occipital lobe ischaemia. 19 Associated agnosia of the cortical blindness is known as Anton syndrome. 19 Intact pupillary light reflex and normal appearing fundi are key diagnostic elements of cortical blindness which localise the lesion to the posterior visual pathway. 19 Symptoms of posterior cerebral artery stroke include contralateral homonymous hemianopia (due to occipital infarction), hemisensory loss (due to thalamic infarction) and hemi-body pain (usually burning in nature and due to thalamic infarction) 3. If bilateral, often there is reduced visual-motor coordination 3.

He had no symptoms of denial of visual deficit at that time. Occipital seizures arising in this area tend to spread to the temporal lobe producing a focal impaired awareness seizure. Superior to the calcarine fissure. Occipital seizures arising in this area can spread to the parietal lobe, fronto-parietal operculum or frontal lobes. Anton syndrome secondary to recurrent bilateral occipital infarct. 2. Case Presentation A 57-year-old man with background history of diabetes The prognosis for patients with cortical blindness depends on the age, medical history, cause, severity, and Symptoms.
