Doctor's Notes on Visual Migraines (Ocular Migraines)
Migraine headaches differ from regular tension headaches in that they cause incapacitating neurological symptoms. Migraine pain often occurs on just one side of the head but it may occur on both sides. Migraine attacks are often accompanied by visual disturbances.
Migraine symptoms that affect vision often occur with a migraine aura and include
- blurred or absent areas in the visual field,
- tunnel vision,
- complete blindness,
- sensitivity to light (photophobia),
- an absent arc or band of vision with a shimmering or glittering zigzag border;
- a sensation of lights, sparks, or colors;
- visual hallucinations, and
- uniform flashes of light.
Head pain from migraine headaches often occurs on one side of the head, but it may be present on both sides. Head pain usually has a slow onset and is typically described as throbbing or pulsing, but maybe a continuous ache.
Other symptoms of migraine headaches include
- sensitivity to sound and/or smells,
- fatigue, mood changes,
- frequent urination,
- sore and stiff neck muscles,
- loss of appetite,
- paleness, and
What Is the Treatment for Visual Migraines (Ocular Migraines)?
Treatment for the visual effects of migraine headaches includes removing migraine triggers, use of medications to prevent a migraine, and medical treatments to lessen the symptoms themselves.
Talk to your doctor about stopping any drugs that worsen the headache (Do not stop any medication without talking to your doctor first.) Migraine sufferers should avoid potential migraine triggers such as:
The following drugs have preventive effects when taken daily. They are mainly useful in people who have more than 1-2 headaches per week. Commonly used medications to prevent migraines include:
- Valproic acid (Depakote)
- Topiramate (Topamax)
- Amitriptyline (Elavil)
- Nortriptyline (Pamelor)
- Propranolol (Inderal) and other beta-blockers
- Verapamil (Covera) and other calcium channel blockers
- Cyproheptadine (Periactin)
Medical therapies (oral medications, injections, or medical devices) prescribed for migraines are used to treat migraine symptoms and keep migraines from occurring. The most commonly used treatments for migraines include:
- Trigger point injections
- OnabotulinumtoxinA (Botox)
- Anti-nausea medications (antiemetics) given in a shot or intravenous (IV)
- Chlorpromazine, prochlorperazine, and diphenhydramine
- Selective serotonin 1F receptor agonist
- Lasmiditan (Reyvow)
- Calcitonin-gene related peptide (CGRP) antagonists
- Rimegepant (Nurtec)
- Ubrogepant (Ubrelvy)
- Ergotamine preparations
- Dihydroergotamine (D.H.E. 45, Migranal)
- Ergotamine (Ergomar)
- Transcutaneous supraorbital nerve stimulation
- Transcranial magnetic stimulation (TMS)
- Remote electrical neuromodulation
- Noninvasive vagus nerve stimulation (nVNS)
- Peripheral nerve blocks
- Occipital nerve blocks
- Sphenopalatine ganglion blocks

Alternative and Complementary Medicine for Migraine and Cluster HeadachesMigraine headaches are intense, recurring headaches that are sometimes accompanied by nausea, vomiting and other symptoms. Alternative therapies that have proven successful for some include: spinal manipulation, acupuncture, and homeopathy.

How Does a Doctor Diagnose a Migraine?A migraine headache causes symptoms such as severe head pain and sensitivity to light, sound, or smells. In order to be diagnosed with migraines, your doctor may prescribe tests such as blood tests, imaging tests (X-rays, computerized tomography [CT] scan, magnetic resonance imaging [MRI] scan), or lumbar puncture.
How Does CGRP Cause Migraine?CGRP (calcitonin gene-related peptide), a protein released around the brain that can dilate blood vessels and cause severe inflammation, is believed to cause the pain of a migraine headache.
Medical AcupunctureThe practice as acupuncture consists of placing fine steel needles placed through the skin and into nodes mapped out in traditional Chinese medicine. Acupuncture was recognized as a legitimate medical practice by the FDA in the 1990s. Independently licensed physicians practice acupuncture for various types of symptom relief.
Migraine and Cluster Headache MedicationsMigraines and cluster headaches are severe recurrent headaches. Medications to treat them fall under a number of different categories. These include triptans and ergot alkaloids for abortive therapy. For preventative therapy, a number of different drug classes are available, including beta blockers, predisone, antidepressants, lithium, antiseizure medications and others.
Migraine and Related HeadachesTwo general types of headaches exist: primary (like migraines and cluster headaches) and secondary (headaches caused by a structural problem, trauma, or infection) Triggers include stress, lack of sleep, not enough food or fluids, and many other causes. A variety of medications all working through a variety of different mechanisms are used to treat migraines.
Migraine HeadacheMigraine headaches are one of the most common problems seen by doctors, Urgent Care Centers, and Emergency Departments. While the exact cause of this type of headache is not clearly understood, researchers and doctors believe they are due to changes in the brain and surrounding blood vessels.Triggers for migraine headache are certain foods (chocolate, cheese, alcohol, msg, etc.), stress, birth control pills, and smoking.Signs and symptoms of a migraine include a variety of warning signs (referred to as “prodome”), for example, feeling "high," irritable, or depressed, migraine aura, headache pain, and migraine pain that resolves. Other migraine symptoms, for example, problems eating, concentrating, and fatigue may linger after the pain is gone.
Migraine Headache FAQsThe difference between headache and migraine often includes intense pain, sensitivity to light, sound and smells, and nausea and vomiting for migraine headache. Migraines last from 4 hours to 3 days and may be preceded by pre-migraine symptoms like auras. The exact cause of migraines is unclear, but numerous triggers can precipitate a migraine attack. Migraines may be managed and/or prevented by a combination of medication and avoiding triggers.
Migraine Headache in ChildrenMigraine is a headache condition that comes back again and again. Ten percent of children get migraines, and an even higher percentage of teenagers have them. Migraines can be managed with a number of different varieties of medications.
What Are Home Remedies to Get Rid of a Migraine Fast?The best way to relieve a migraine is to try to stop a migraine attack before it happens. As soon as you feel a migraine coming on, you should try home remedies such as ice, heat, breathing techniques, getting fresh air, staying hydrated, and getting to a darkened room to avoid light (a migraine trigger).
What Causes Migraines?Researchers assume migraine occurs because of an imbalance in the level of neurotransmitters in the brain. The resulting imbalance causes the nerve cells to undergo changes responsible for headaches. The trigeminal nerve (the fifth cranial nerve) may also be involved in these pain mechanisms.
What Causes Ocular Migraines?Ocular migraines are a type of migraine that causes vision changes such as small blind spots, vision loss, flashes of light, zig-zag lines, or seeing stars. The cause of ocular migraines is unknown, but may be caused by abnormal brain activity. Risk factors include genetics and hormones.
What Is the Main Cause of Migraine?It is not known what causes migraines, but genetics and environment are factors. The main triggers of migraines include stress, poor sleep, hormones, caffeine, alcohol, weather changes, certain foods, dehydration, bright lights, certain smells, and medication overuse.
What Triggers an Ocular Migraine?Harsh lighting, long screen time, other visual strain, stress, dehydration, food additives, and other causes all may trigger an ocular migraine, a subtype that focuses in the eye and causes vision changes.
Worst Headache of Your LifeThe worst headache of your life may be a life-threatening emergency. Symptoms such as a headache with fever and a stiff neck, a headache that starts with a thunderclap, a headache following a head injury, a headache with loss of vision or numbness of the arms or legs, or a headache with a fever (not caused by the flu) are emergent medical conditions. Treatment of the worst headache of your life depends on the cause of the headache.
