Source: bing.comA retinal migraine is a rare type of migraine that causes temporary vision loss in one eye. It is also known as an ocular migraine or a visual migraine. The condition affects the blood vessels in the eye and can affect people of any age, sex, or race. In this article, we will discuss the causes, symptoms, diagnosis, and treatment options for retinal migraines.
Causes of Retinal Migraines
Source: bing.comThe exact cause of retinal migraines is not known. However, it is believed to be related to the abnormal functioning of blood vessels in the eye. The blood vessels in the retina, which is a layer of tissue at the back of the eye that senses light and sends visual signals to the brain, can spasm or constrict during a migraine attack, causing temporary vision loss in one eye.
Other factors that may trigger a retinal migraine include stress, hormonal changes, certain foods, lack of sleep, and physical activity. People who have a family history of migraines are also at a higher risk of developing retinal migraines.
Symptoms of Retinal Migraines
Source: bing.comThe main symptom of a retinal migraine is temporary vision loss in one eye. The loss of vision can last from a few seconds to an hour and is usually followed by a headache. Other symptoms that may occur during a retinal migraine include:
- Flashing or flickering lights in the affected eye
- Blurred vision
- Seeing a zigzag pattern or a blind spot
- Numbness or tingling in the face, arms, or legs
- Dizziness or vertigo
Diagnosis of Retinal Migraines

The doctor will perform a comprehensive eye exam to determine if there is an underlying eye condition that may be causing the symptoms. They may also ask you about your medical history and perform other tests such as a visual field test, a blood test, or an MRI to rule out other causes of vision loss.
Treatment of Retinal Migraines

- Triptans, which are migraine-specific drugs that help relieve headache pain and other symptoms
- Beta-blockers, which are used to reduce the frequency and severity of migraines
- Anti-seizure drugs, which are sometimes used to prevent migraines

- Getting regular exercise
- Maintaining a healthy diet
- Getting enough rest and sleep
