Differential Diagnosis for Patient Complaining of Strobe Lights in Vision

  • Single Most Likely Diagnosis
    • Migraine with aura: This condition is characterized by visual disturbances, including flashing lights or strobe-like effects, often preceding a headache. The symptoms described by the patient are classic for a migraine aura, making it the most likely diagnosis.
  • Other Likely Diagnoses
    • Ocular migraine: Similar to migraine with aura but without the subsequent headache, ocular migraines can cause transient visual symptoms including seeing strobe lights.
    • Photosensitive epilepsy: Although less common, this condition can cause visual disturbances, including seeing flashing lights, in response to certain visual stimuli.
    • Retinal detachment: Symptoms can include flashes of light, but typically, these are accompanied by other signs like floaters or a curtain descending over the visual field.
  • Do Not Miss Diagnoses
    • Stroke or transient ischemic attack (TIA): While less likely, a stroke or TIA can present with sudden visual disturbances, including flashing lights, especially if the posterior circulation is involved. Missing this diagnosis could be catastrophic.
    • Pituitary apoplexy: A rare but potentially life-threatening condition where a pituitary tumor suddenly hemorrhages, leading to acute symptoms that can include visual disturbances.
    • Temporal lobe seizures: These can cause a variety of visual and sensory disturbances, including the perception of flashing lights, and are critical not to miss due to their implications for seizure management.
  • Rare Diagnoses
    • Charles Bonnet syndrome: A condition in visually impaired individuals where they experience complex visual hallucinations, which could potentially include seeing strobe lights.
    • Hallucinogenic drug use: Certain drugs can cause visual disturbances, including seeing flashing lights or patterns.
    • Vitamin B12 deficiency: Though very rare, severe deficiencies can lead to neurological symptoms, including visual disturbances, though these are typically not the first or most prominent symptoms.
