How are ophthalmologic migraine symptoms managed?

Management of Ophthalmologic Migraine Symptoms

For ophthalmologic migraine symptoms, first-line treatment includes NSAIDs such as acetylsalicylic acid, ibuprofen, or diclofenac potassium, with triptans as second-line therapy when NSAIDs are insufficient. 1

Understanding Ophthalmologic Migraine

Ophthalmologic migraine (also known as migraine with visual aura) is characterized by fully reversible visual symptoms that typically precede or accompany headache. These symptoms may include:

• Visual disturbances (most common aura symptom)
• Scintillating scotomas (flashing lights)
• Fortification spectra (zigzag patterns)
• Visual field defects
• Blurred vision

According to the International Classification of Headache Disorders (ICHD-3), migraine with aura requires at least two attacks with one or more fully reversible aura symptoms (visual, sensory, speech/language, motor, brainstem, or retinal) 1.

Diagnostic Approach

Diagnosis requires careful assessment of:

• Visual symptoms that spread gradually over ≥5 minutes
• Duration of individual aura symptoms (typically 5-60 minutes)
• Timing of headache (aura is usually accompanied by or followed by headache within 60 minutes)
• Pattern of symptoms (aura symptoms often occur in succession)

Important: While visual symptoms are typically transient, some patients may experience prolonged visual disturbances. Any persistent visual field defects lasting more than 7-10 days require thorough evaluation to rule out other causes 2.

Treatment Algorithm

1. Acute Treatment

• First-line therapy:

  • NSAIDs: acetylsalicylic acid (650-1000 mg), ibuprofen (400-800 mg), or diclofenac potassium 1
  • Take early in the headache phase for maximum effectiveness

• Second-line therapy:

  • Triptans when NSAIDs provide insufficient relief 1
  • Consider combining triptans with fast-acting NSAIDs to prevent recurrence

• Third-line therapy:

  • Newer options like ditans and gepants 1

• Adjunctive therapy for nausea/vomiting:

  • Prokinetic antiemetics: domperidone or metoclopramide 1

2. Preventive Treatment

Consider preventive therapy when:

• Attacks occur ≥2 days per month despite optimized acute therapy
• Attacks significantly impair quality of life
• Risk of medication overuse headache exists

Preventive options include:

• Beta-blockers (propranolol)
• Tricyclic antidepressants (amitriptyline)
• Anticonvulsants (topiramate) - monitor for metabolic acidosis and visual side effects 3
• CGRP monoclonal antibodies for refractory cases 1

Special Considerations

Visual Field Defects

• While most visual symptoms resolve within 60 minutes, some patients may experience prolonged visual disturbances 4
• Research suggests that 35% of migraine patients may have some form of visual field abnormality 5
• Persistent visual field defects warrant neuroimaging to rule out other causes 2

Medication Overuse Risk

• Limit use of acute medications to avoid medication overuse headache (MOH)
• MOH criteria: regular overuse of acute medications for >3 months (≥15 days/month for simple analgesics or ≥10 days/month for other medications) 1

Medications to Avoid

• Oral ergot alkaloids (poorly effective and potentially toxic)
• Opioids and barbiturates (questionable efficacy, risk of dependency) 1

Monitoring and Follow-up

• Use headache diaries to track frequency, duration, and response to treatment
• Assess effectiveness and adverse events of medications
• Review diagnosis and treatment strategy if outcomes are suboptimal
• Consider specialist referral for patients with chronic migraine or persistent visual symptoms 1

Remember that ophthalmologic migraine symptoms typically resolve completely, but persistent visual disturbances require thorough evaluation to rule out other neurological conditions.
