Differential Diagnosis for I Deviation in Occipital Strokes

• Single Most Likely Diagnosis
  • Hemianopic visual field defect: This is the most likely diagnosis because occipital strokes often result in visual field defects, including homonymous hemianopia, which can cause deviation in vision perception.
• Other Likely Diagnoses
  • Visual neglect: This condition, often associated with parietal lobe damage, can also occur with occipital strokes and leads to a deviation in attention and perception towards one side of the visual field.
  • Balint's syndrome: A rare condition characterized by ocular apraxia, optic ataxia, and simultanagnosia, which can result from bilateral occipital or parieto-occipital lesions, potentially causing deviation in visual processing.
• Do Not Miss Diagnoses
  • Cerebral vasculitis: Although less common, cerebral vasculitis can cause strokes, including in the occipital region, and missing this diagnosis could lead to inadequate treatment and severe consequences.
  • Migraine with aura: Some migraine auras can mimic the visual disturbances seen in occipital strokes, including deviation in visual perception, and are important to distinguish due to different management strategies.
• Rare Diagnoses
  • Occipital lobe epilepsy: Seizures originating from the occipital lobe can cause transient visual disturbances, including deviation in visual perception, and are a rare but important consideration in the differential diagnosis.
  • Progressive visual field defects from other causes (e.g., tumors, abscesses): While rare, other space-occupying lesions in the occipital region can cause gradual visual field defects and deviation, emphasizing the need for thorough diagnostic evaluation.
