Cerebral infarction can cause blurred vision, which is commonly seen in the following conditions: 1. Brainstem infarction, when the midbrain or pontine brain is involved, involving the nucleus of the oculomotor nerve or the nucleus of the abducens nerve, eye movement disorders are likely to occur, resulting in bilateral eye movements that are not co-axial and two imaging in the retina, leading to blurred or double vision or double vision. 2. Damage to the visual pathway, there is a visual pathway from the optic nerve to the occipital lobe, in which The visual pathway from the optic nerve to the occipital lobe has a visual pathway, and damage to any part of it may lead to visual impairment, which may include blurred vision, diplopia, or hemianopia. 3. Damage to the visual center, most commonly seen in occipital lobe infarction, but also in basilar artery apical syndrome, is most common with visual field defects, which often manifest as blurred vision if the degree of injury is not severe.
