The term retinal migraine is often misunderstood to mean any migraine that involves any visual symptoms or a migraine with visual symptoms but without the headache phase of the attack. The retinal migraine is a type of migraine that results in temporary vision loss or disturbance of vision of one eye. It is a rare type of migraine that involves aura. Unlike most migraines with aura, a retinal migraine affects vision in one eye only. According to the best retina specialists of Sohna road, retinal migraine is identified when repeated attacks of visual disturbances occur in only one eye before the headache phase of the migraine attack. The criteria for identifying retinal migraines include vision change in one eye along with a headache. The vision change may consist of flickering lights or temporary blindness. The visual disturbance lasts no longer than an hour but the headache associated can last from a few hours to a few days. It is more common in women than in men. The attack of this migraine varies in frequency, but many people who experience them will have one in every few months. There is a small risk with a retinal migraine that the sudden reduction in blood flow to the eye may damage its retina and blood vessels. Therefore, it is better to know about the causes, symptoms and preventative measures of this disease.
Dr. Kapil Chopra from Chopra’s Eye and Dental Care clinic explains that retinal migraine is caused when the blood vessels to the eye suddenly start narrowing (constricting), reducing the blood flow to the eye. As the blood vessel relaxes and blood flow returns to normal, the symptoms usually disappear, and vision comes back. Here are the few causes of retinal migraine:-
- Medications that lead to swelling in blood vessels and regular use of painkillers for headaches can cause retinal migraine.
- Sensitivity to ingredients in specific foods is another cause of this eye disease.
- Changes in sleeping schedules also lead to retinal migraines.
- Too many bright lights or loud noises also cause retinal migraines.
- Stress, tension and being overtired can also be the reasons for retinal migraine.
- Starving oneself i-e not eating and drinking enough.
- Excessive caffeine or caffeine withdrawal also causes retinal migraines.
A retinal migraine attack begins with monocular (in one eye) visual symptoms that can include:
- Scintillations i-e seeing twinkling lights
- Scotoma i-e areas of decreased or lost vision
- Temporary blindness
Top eye clinics in Gurgaon underline that retinal migraine involves repeated attacks of visual disturbances and then headaches. The visual disturbances may last up to an hour but headache can continue for some time after. The visual disturbances collectively are often called an aura. The characteristics of an aura include temporary blindness, partial loss of vision and flashing or twinkling lights. The aura lasts between 5 and 60 minutes. Within an hour of the visual symptoms beginning, the headache phase of retinal migraine may begin. This migraine headache is nauseating, pulsing and causes sensitivity to light as well as intolerance to sound.
We all know prevention is better than cure and when it comes to the health of your eyes, you can’t afford to take risks. The best eye specialist in Sohna road recommends some preventive measures which will help you to prevent yourself from retinal migraine. These include:-
