Migraine episodes approximately twice per month with good response to pain medication. A January 2021 research review found that more than 11 percent of study participants with COVID-19 had eye symptoms. People who develop COVID-19 sometimes develop symptoms affecting their eyes. Severe neurological complications such as stroke or seizure have also been reported, although these aren’t common with COVID -19. Some people without a history of migraine report experiencing migraine-like headaches.Ī 2020 study found that among 47 people with COVID-19 who reported having headaches, 24 people (51 percent) reported migraine-like headaches, while 40 percent had symptoms of a tension headache.īefore they developed COVID-19, only 12 of the study participants had previously experienced migraine episodes.Īccording to a June 2020 research review, the most commonly reported neurological symptoms of COVID-19 are headache and loss of smell. Some people with a previous history of migraine report worsening migraine episodes during COVID-19. Is ocular migraine a symptom of COVID-19? ![]() Visual disturbances can include:Īmong people who experience an aura, about 99 percent have at least one visual symptom with some of their auras. Usually, people who have migraine with aura don’t experience an aura with all of their migraine episodes, just with some of them.Īn aura is a temporary visual, auditory, motor, or other sensory change. Migraine tends to run in families.Ī migraine aura is experienced by about 25 percent of people with migraine, either before or at the same time as a migraine episode. Migraine is a neurological condition that often causes intense headaches. You may experience flashes or mosaic patterns of light.Īs of now, there’s no research connecting this specific type of migraine to COVID-19. Your vision may also become blurry or dim. Partial or total vision loss typically lasts 10 to 20 minutes before returning to normal. Other researchers suggest electrical changes in the neurons of the retina cause them. Some researchers point to a possibility that a narrowing of the retinal or ciliary arteries causes them. The reason why these migraine episodes develop is controversial. Retinal migraine is a condition that causes partial or full vision loss in one eye and a headache within 60 minutes of vision loss. Sometimes it’s used to specifically refer to a type of migraine called retinal migraine. People who have migraine with aura are at a mildly increased risk of stroke.The term “ ocular migraine” is often used to refer to any type of headache that causes visual changes. Migraines are also more common in women than in men. Risk factorsĪlthough no specific factors appear to increase the risk of migraine with aura, migraines in general seem to be more common in people with a family history of migraine. Many of the same factors that trigger migraine can also trigger migraine with aura, including stress, bright lights, some foods and medications, too much or too little sleep, and menstruation. The electrical and chemical waves can occur with normal functioning of the nerves and do not cause harm to the brain. The most common type of aura is visual aura, which occurs when a wave of electrical activity spreads through the visual cortex and causes visual symptoms. This electrical or chemical wave can occur in areas that process sensory signals, speech centers or centers that control movement. The part of the brain where the electrical or chemical wave spreads determines the type of symptoms you might experience. There is evidence that the migraine aura is due to an electrical or chemical wave that moves across the brain. ![]() Your doctor will need to rule out more-serious conditions, such as a stroke. ![]() ![]() See your doctor immediately if you have new signs and symptoms of migraine with aura, such as temporary vision loss, speech or language difficulty, and muscle weakness on one side of your body. Numbness, typically felt as tingling in one hand or on one side of your face that may spread slowly along a limb.Other temporary disturbances sometimes associated with migraine aura include: Zigzag lines that gradually float across your field of vision.Blind spots (scotomas), which are sometimes outlined by simple geometric designs.Most people who have migraine with aura develop temporary visual signs and symptoms, which tend to start in the center of the field of vision and spread outward. Sometimes migraine aura occurs without headache, especially in people age 50 and older. Migraine aura usually occurs within an hour before head pain begins and generally lasts less than 60 minutes. Migraine aura symptoms include temporary visual or other disturbances that usually strike before other migraine symptoms - such as intense head pain, nausea, and sensitivity to light and sound.
