  2. Occipital neuralgia - Wikipedia

    en.wikipedia.org/wiki/Occipital_neuralgia

    Occipital neuralgia is caused by damage to the occipital nerves, which can arise from trauma (usually concussive or cervical), physical stress on the nerve, repetitive neck contraction, flexion or extension, and/or as a result of medical complications (such as osteochondroma, a benign bone tumour).

  3. Occipital epilepsy - Wikipedia

    en.wikipedia.org/wiki/Occipital_epilepsy

    Seizures originate in the occipital lobe and account for 5 to 10 percent of all epileptic seizure types. Generally, this type of epilepsy can have an onset anywhere from 1–17 years old in children, but the patient prognosis is good. Since the event is located in the occipital lobe, symptoms may occur spontaneously and include visual stimuli.

  6. Aura (symptom) - Wikipedia

    en.wikipedia.org/wiki/Aura_(symptom)

    Visual auras can be simple or complex. Simple visual symptoms can include static, flashing, or moving lights/shapes/colors caused mostly by abnormal activity in the primary visual cortex. Complex visual auras can include people, scenes, and objects which results from stimulation of the temporo-occipital junction and is lateralized to one hemifield.

  7. Visual pathway lesions - Wikipedia

    en.wikipedia.org/wiki/Visual_pathway_lesions

    The visual cortex located in the occipital lobe of the brain is that part of the cerebral cortex which processes visual information. [26] Cortical blindness refers to any partial or complete visual deficit that is caused by damage to the visual cortex in the occipital lobe. Unilateral lesions can lead to homonymous hemianopias and scotomas.

  8. Photopsia - Wikipedia

    en.wikipedia.org/wiki/Photopsia

    Impaired blood flow to the cells of the occipital lobe (ischemia, for example as caused by a TIA or Vertebrobasilar insufficiency) will lead to temporary visual problems; if the poor blood flow is sustained it will lead to cell death (infarction, for example as caused by a stroke) which may cause persistent visual problems.

  9. Homonymous hemianopsia - Wikipedia

    en.wikipedia.org/wiki/Homonymous_hemianopsia

    Similarly, a person who has a stroke to the right occipital lobe will have the same visual field defect, usually more congruent between the two eyes, and there may be macular sparing. A stroke on the right side of the brain (especially parietal lobe), in addition to producing a homonymous hemianopsia, may also lead to the syndrome of ...
