2. Cortical blindness - Wikipedia

   en.wikipedia.org/wiki/Cortical_blindness

   Acquired cortical blindness is most often caused by loss of blood flow to the occipital cortex from either unilateral or bilateral posterior cerebral artery blockage (ischemic stroke) and by cardiac surgery. [2] In most cases, the complete loss of vision is not permanent and the patient may recover some of their vision (cortical visual ...

3. Hemianopsia - Wikipedia

   en.wikipedia.org/wiki/Hemianopsia

   Paris as seen with left homonymous hemianopsia. A homonymous hemianopsia is the loss of half of the visual field on the same side in both eyes. The visual images that we see to the right side travel from both eyes to the left side of the brain, while the visual images we see to the left side in each eye travel to the right side of the brain.

4. Ocular ischemic syndrome - Wikipedia

   en.wikipedia.org/wiki/Ocular_ischemic_syndrome

   Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. [1] Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...

5. Homonymous hemianopsia - Wikipedia

   en.wikipedia.org/wiki/Homonymous_hemianopsia

   Hemianopsia, or hemianopia, is a visual field loss on the left or right side of the vertical midline. It can affect one eye but usually affects both eyes. Homonymous hemianopsia (or homonymous hemianopia) is hemianopic visual field loss on the same side of both eyes. Homonymous hemianopsia occurs because the right half of the brain has visual ...

6. Topographical disorientation - Wikipedia

   en.wikipedia.org/wiki/Topographical_disorientation

   Topographical disorientation is the inability to orient oneself in one's surroundings, sometimes as a result of focal brain damage. [1] This disability may result from the inability to make use of selective spatial information (e.g., environmental landmarks) or to orient by means of specific cognitive strategies such as the ability to form a mental representation of the environment, also known ...

7. Visual pathway lesions - Wikipedia

   en.wikipedia.org/wiki/Visual_pathway_lesions

   Visual field-bitemporal hemianopia Visual field-binasal hemianopia. A lesion involving complete optic chiasm, which disrupts the axons from the nasal field of both eyes, causes loss of vision of the right half of the right visual field and the left half of the left visual field. [3] This visual field defect is called as bitemporal hemianopia.

9. Visual system - Wikipedia

   en.wikipedia.org/wiki/Visual_system

   According to Pollock et al. (2010) stroke is the main cause of specific visual impairment, most frequently visual field loss (homonymous hemianopia, a visual field defect). Nevertheless, evidence for the efficacy of cost-effective interventions aimed at these visual field defects is still inconsistent. [53]
