There has been a report of a person who, after receiving the COVID-19 vaccine, has experienced an oppressive headache. Can migraine occur after the COVID-19 vaccine? In some cases,⁴ people who contract COVID-19 have experienced headaches without aura long after recovering from the virus. ![]() However, many people who have regularly had migraines throughout their life find themselves experiencing migraine with aura for the first time after contracting COVID-19. Their headaches simply don't present in conjunction with any visual abnormalities. Many people who experience migraines never experience an ocular migraine. The link between COVID-19 and ocular migraine Because of this, your doctor may recommend some medications and suggest treatment for other stroke risk factors. It's rare for this damage to result in permanent vision loss, however.įor some people, migraine with aura can increase the risk of stroke. However, in the case of retinal migraine caused by decreased blood flow, there is a small chance that the lack of blood can damage the vessels in the eye. ![]() In most cases, the condition is nothing to worry about. The symptoms of ocular migraine are annoying but temporary. Because of this, the visual effects should disappear when you close the affected eye.

The patterns caused by the ocular migraine result from these electrical abnormalities spreading across different parts of the visual cortex. For migraine with aura, this abnormal activity is located in the visual cortex area of the brain. The aura of migraine with aura and the visual disturbances of retinal migraine are both caused¹ by abnormal electrical activity. Retinal migraine is a rare subtype of ocular migraine, while migraine with aura is the more common version. In addition to seeing stars, people experiencing a retinal migraine may notice decreased vision, temporary blindness, or even irreversible visual loss as a complication. ![]() In migraine with aura, a person may see stars, flashes of light, or experience blind spots.
