HAVE YOU EVER HAD AN OCULAR MIGRAINE?
Published on
Ocular migraine, also known as visual aura, is a type of headache characterised by temporary visual symptoms. These may occur on their own or accompany the headache, appearing before, during or after the episode. Symptoms can affect one or both eyes and usually include:
- Scotomas: Partial loss of vision, with grey or dark areas in the visual field.
- Shimmering or flickering lights: Central flashes of light, zigzag lines or geometric patterns.
- Blurred vision: Vision may become hazy or unclear.
- Other visual symptoms: Seeing wavy lines or fixed spots that appear and disappear.
These symptoms usually last between 10 and 30 minutes, although in some cases they can extend to several hours.
Causes of ocular migraine
The exact cause of ocular migraine is not fully understood, but it is thought to be related to changes in blood flow in the brain. Common triggers include:
- Stress and anxiety.
- Fatigue and lack of sleep.
- Hormonal changes, such as those associated with the menstrual cycle.
- Consuming certain foods and drinks, such as chocolate, red wine, coffee and processed foods.
- Changes in the weather or barometric pressure.
- Exposure to bright or flickering lights.
Treatment for ocular migraine
Treatment for ocular migraine includes avoiding known triggers and using painkillers such as paracetamol or ibuprofen. It is essential for people experiencing ocular migraine symptoms to consult an ophthalmologist for an accurate diagnosis. In rare cases, visual symptoms may indicate other eye or neurological diseases, so ruling out other causes is essential.
