• Cause of Ocular Attack?
Even if pain is not experienced during an ocular migraine, the reasons for the cause of the attack are the same. The inflammation of the blood vessels and nerves that surround the brain changes the blood flow which contributes to the visual migraine symptoms.
An Ocular migraine attack can last from as little as a few seconds to up to half an hour. The visual disturbances a person sees can be very disturbing and often disorientating. There is however, no lasting or permanent damage to the eye. Although this is the case, anyone experiencing a visual migraine should always consult a doctor as there are other conditions that can cause visual disturbances.
• Dangers
Since someone who is having an migraine attack can suffer considerable visual impairment, it is advisable to be aware of when an attack is coming on and take precautions to ensure your safety. This is particularly important when driving, crossing the road or using machinery. It is always best to stop what you are doing until the attack passes. As some people can temporarily become blind in one eye.
• Cause of Ocular Migraine?
Despite much medical research and technological advancements the cause of ocular migraine is still unknown. However, it is well known that certain triggers can bring on an attack of any type of migraine including ocular migraine. Such triggers include, stress, fatigue, alcohol and smoking. Some foods can trigger an attack, caffeine, cheese, chocolate and citrus fruit have all been linked to migraine attacks. Even certain smells such as perfume can bring on an attack. Flashing or flickering lights can also trigger an attack.
• Diary Keeping
It is for this reason that it is well worth keeping a diary if you are a frequent migraine sufferer. Recording when you have an attack and what happened or what you have eaten prior to an attack can be very useful in managing your own ocular migraine attacks and limiting them.
• Eye Exercises
One suggested way to minimize the recurrence of ocular migraines is by practicing eye exercises. This is especially useful for those who do a lot of close up work or spend long periods of time on the computer. Roll your eyes up and down and then from side to side. This helps to stretch the muscles in the eyes.
Often when ocular migraine sufferers only experience attacks infrequently, medication may not be prescribed. However, if you suffer severe pain with the attack there are many good painkillers to deal specifically with migraine pain.

Many people who have an migraine attack may not realize it is a migraine, especially if they suffer no pain that is associated with migraines. Fortunately, ocular migraines are mostly harmless. Resting and waiting until the symptoms have passed is really the only remedy once one has started.
