    \n\t\t<\/svg>Definition<\/span>\n\t\t\t

    Ocular migraine<\/strong> (noun, informal term)<\/em>: a temporary visual disturbance, such as flashing lights, zigzag lines or a blind spot, that comes on during or around a migraine and then fully clears. Doctors use the phrase for two different conditions: migraine with visual aura, which is common and starts in the brain’s visual centres, and retinal migraine, which is rare, affects one eye only and can be diagnosed only after other causes of temporary sight loss are excluded.<\/p>\n\t\t<\/div><\/div><\/div><\/div><\/section>\n\n\n\n\n

    Quick answer.<\/strong> An ocular migraine is a short, fully reversible visual disturbance linked to migraine, usually lasting 5 to 60 minutes. Most cases are a migraine aura that affects both eyes, even though it can feel as if it is in one. True one-eye (retinal) migraine is rare. Sudden loss of vision, or a first-ever aura after 40, needs a doctor. At Laser Istanbul Clinic, our eye surgeons can examine your eyes to rule out eye causes.<\/p><\/div><\/div><\/div><\/div><\/section>\n\n\n\n\n

    What is an ocular migraine? Two different conditions<\/h2>\n\t\t\t

    “Ocular migraine” is not a single official diagnosis.<\/strong> A 2021 narrative review in the journal Vision<\/em> explains that the terms “ocular migraine”, “ophthalmic migraine” and “retinal migraine” have been used interchangeably for decades, which has caused confusion for both doctors and patients. In practice the phrase covers two things:<\/p>\n\t\t\t

    <\/th>Migraine with visual aura<\/th>Retinal migraine<\/th><\/tr><\/thead>
    How common<\/th>Common: visual aura occurs in over 90% of people with migraine with aura, at least in some attacks (ICHD-3)<\/td>Rare: described by the International Headache Society as “extremely rare”<\/td><\/tr>
    Which eye<\/th>Both eyes. The disturbance is in one side of the visual field of both eyes, even though it can feel as if it comes from one eye<\/td>One eye only, by definition<\/td><\/tr>
    Where it starts<\/th>In the brain’s visual cortex<\/td>Debated: the retina or its blood supply, or a migraine-type process; the 2021 review calls the name “potentially a misnomer”<\/td><\/tr>
    Typical symptoms<\/th>Flickering zigzag or shimmering shapes that expand, then a blind spot<\/td>One eye sees flashes, a blind spot or loses vision, then recovers<\/td><\/tr>
    Duration<\/th>5 to 60 minutes<\/td>The ICHD-3 criteria include symptoms lasting 5 to 60 minutes<\/td><\/tr>
    How it is diagnosed<\/th>From the story and pattern, after a check that nothing else is going on<\/td>Only after other causes of temporary one-eye vision loss are ruled out<\/td><\/tr><\/tbody><\/table><\/div>

    Why the confusion?<\/strong> Our visual field is wider on the temple side (about 90 degrees) than on the nose side (about 60 degrees), so when half of the vision in both eyes is affected, people often feel it only in the eye with the larger lost area. The 2021 review points out that many patients who describe a “one-eye” problem in fact have a symptom shared by both eyes. A simple check is to cover one eye at a time during an episode and note what each eye sees.<\/p><\/div>\t<\/div><\/div><\/div><\/section>\n\n\n\n\n

    Ocular migraine symptoms: what does it look like?<\/h2><\/div>

    The most common ocular migraine symptom is a flickering or zigzag shape that slowly spreads across your vision.<\/strong> The International Headache Society (ICHD-3) calls the classic form a “fortification spectrum”: a zigzag figure near the point you are looking at that gradually spreads to one side, with a shimmering, angled edge, and leaves a blind patch (scotoma) behind as it moves. Research reviews describe it as starting small, often as a flickering blind spot or as flashes or balls of light, and expanding in a C-shape over 5 to 60 minutes.<\/p>\n
