Light Sensitivity/Migraine

Ocular migraines are temporary visual disturbances. Although they can be alarming, they’re usually nothing to worry about and symptoms will normally disappear on their own after around 30 minutes.

An ocular migraine happens when the blood flow to the eye becomes restricted due to a sudden narrowing of the blood vessels. Once the vessels relax, normal blood flow returns and symptoms clear. Usually, this will have no lasting damage to the eye.

Common triggers include:

  • Stress
  • High blood pressure
  • Dehydration
  • Low blood sugar
  • Excessive heat
  • Exercise
  • Bending over
  • Smoking
  • Certain types of contraceptives

They’re also more common in women, people over 40, and those with a family history of migraines or headaches.

Avoiding these triggers is the first step in preventing ocular migraines. So keep a note of when you get an attack so that you can work out what your trigger is.

Ocular migraines can be diagnosed by examining the eyes and asking a series of questions about the symptoms. It’s important to rule out other conditions with similar symptoms.

Once diagnosed, treatment for the ocular migraines and advice on preventing them can be discussed.
