Clinical Manifestations of Ocular Migraine

Visual Aura Characteristics

Ocular migraine presents with repeated attacks of monocular visual disturbances, including scintillations, scotomas, or transient blindness, that are fully reversible and typically followed by migraine headache within 60 minutes, as recommended by the American Academy of Otolaryngology-Head and Neck Surgery 1, 2
Bright scintillating lights or zigzag lines are the most characteristic positive visual phenomena, often appearing as shimmering or flickering patterns, according to the American Academy of Otolaryngology-Head and Neck Surgery 1, 3
Scotomas (blind spots) that interfere with reading and central vision, representing negative visual phenomena, are reported by the American Academy of Otolaryngology-Head and Neck Surgery 1, 3
Visual symptoms typically expand gradually over 5-20 minutes, which helps differentiate them from vascular events like transient ischemic attacks, as stated by the American Academy of Otolaryngology-Head and Neck Surgery 1
The duration of individual visual symptoms ranges from 5-60 minutes, with complete resolution expected, as noted by the American Academy of Otolaryngology-Head and Neck Surgery 1, 4

Visual disturbances develop gradually with spreading characteristics over at least 5 minutes, according to the American Academy of Otolaryngology-Head and Neck Surgery 1, 4
Multiple aura symptoms may occur in succession rather than simultaneously, as reported by the American Academy of Otolaryngology-Head and Neck Surgery 1, 4
Headache follows within 60 minutes of the visual symptoms in most cases, though some patients experience visual symptoms without subsequent headache, as stated by the American Academy of Otolaryngology-Head and Neck Surgery and Nature Reviews Neurology 1, 2

When headache accompanies the visual symptoms, it typically demonstrates unilateral location affecting one side of the head, as noted by the American Academy of Otolaryngology-Head and Neck Surgery 4, 5
The headache has a pulsating quality rather than constant pressure, according to the American Academy of Otolaryngology-Head and Neck Surgery 4, 5
The pain intensity is moderate to severe, interfering with daily activities, as reported by the American Academy of Otolaryngology-Head and Neck Surgery 4, 5
The headache is aggravated by routine physical activity, such as walking or climbing stairs, as stated by the American Academy of Otolaryngology-Head and Neck Surgery 4, 5

Photophobia (light sensitivity) occurs before, during, or after visual symptoms, according to the American Academy of Otolaryngology-Head and Neck Surgery 1, 5
Phonophobia (sound sensitivity) is a transient bilateral phenomenon, as reported by the American Academy of Otolaryngology-Head and Neck Surgery 1, 3
Nausea and/or vomiting occur during the headache phase, as noted by the American Academy of Otolaryngology-Head and Neck Surgery 4, 5

At least 2 attacks fulfilling the characteristic pattern are required for diagnosis, as stated by the American Academy of Otolaryngology-Head and Neck Surgery 1, 4
Complete reversibility of all visual symptoms is mandatory, with persistent deficits suggesting alternative diagnoses, according to the American Academy of Otolaryngology-Head and Neck Surgery 1
