Differential Diagnosis for Changes in Vision when Turning Head

  • Single most likely diagnosis
    • Benign Paroxysmal Positional Vertigo (BPPV): This condition is characterized by brief, episodic vertigo triggered by specific head movements, which can also cause transient changes in vision. The symptoms are usually related to the movement of the head, making it a likely cause for vision changes when turning the head.
  • Other Likely diagnoses
    • Vestibular Migraine: This condition can cause vertigo, headache, and visual disturbances, including blurred vision or sensitivity to light, which can be exacerbated by head movements.
    • Cervicogenic Dizziness: This refers to dizziness that originates from the cervical spine and can be triggered by certain head movements, potentially causing changes in vision.
    • Labyrinthitis: An inner ear disorder that can cause vertigo, dizziness, and vision changes, especially when moving the head.
  • Do Not Miss diagnoses
    • Stroke or Transient Ischemic Attack (TIA): Although less common, a stroke or TIA can present with sudden visual changes, especially if the posterior circulation is involved. It's crucial to rule out these conditions due to their high morbidity and mortality.
    • Multiple Sclerosis: This autoimmune disease can cause a wide range of neurological symptoms, including vision problems that might be exacerbated by head movements.
    • Vertebrobasilar Insufficiency: This condition involves decreased blood flow in the posterior circulation of the brain and can cause symptoms such as dizziness, vertigo, and visual disturbances with head movements.
  • Rare diagnoses
    • Chiari Malformation: A structural defect in the cerebellum that can cause a range of neurological symptoms, including vision changes with certain head movements, due to compression of the brainstem and cerebellum.
    • Superior Canal Dehiscence: A rare condition where there is an abnormal opening in the bone overlying the superior canal of the inner ear, leading to vertigo and visual disturbances with sound or pressure changes, including head movements.
