Nov 5, 2018 Homonymous hemianopia is the most frequent visual field defect in patients visual field defects are typical of occipital lobe infarcts.

Homonomous Hemianopia When the stroke affects most of the occipital lobe on one side of the brain, the visual problem that arises is called homonymous hemianopia. 3 This describes loss of half of the vision out of each eye. A stroke survivor who has homonymous hemianopia is not able to see objects that are on the opposite side of the stroke.

Good case of acute PCA infarct causing a typical visual defect for disruption of the optic pathway posterior to the thalami (ie homonymous hemianopia). Chronic microangiopathic changes in this case were due to a long history of vasculopathy and multiple CVA risk factors. Homonymous visual field (VF) defects impair visual function and frequently preclude driving ().Stroke is the most common cause of homonymous hemianopia (HH) and approximately 10% of patients with stroke are found to have a HH, which may affect their functional neurologic outcome (). It can also be caused by bilateral inferior quadranopsias from superior lesions on both sides of the occipital lobe.
