At Blue Fin Vision®, London’s premier eye clinic, we understand that experiencing ocular migraines can be alarming, especially if they occur suddenly. If you’ve found yourself asking, “Why am I getting ocular migraines?” you’re not alone. This comprehensive guide will explore the causes, symptoms, and treatments of ocular migraines, helping you understand this condition and how our expert team can assist you.
Understanding Ocular Migraines
Ocular migraines, also known as retinal migraines, are a type of migraine that primarily affects your vision. Unlike traditional migraines, ocular migraines may not always be accompanied by headache pain. They are characterised by temporary visual disturbances that typically affect one eye.
A Unique Characteristic of Ocular Migraines
One of the most distinctive features of ocular migraines is that the visual phenomena are perceived even with both eyes closed. This crucial characteristic distinguishes ocular migraines from other visual problems:
- When you close both eyes, the visual disturbances remain just as visible.
- This indicates that the phenomena aren’t being “seen” in the traditional sense – no light is entering the eye and stimulating the retina.
- Instead, these visual disturbances are being “perceived” by the brain itself.
This unique aspect of ocular migraines highlights their neurological nature and can be a key factor in diagnosis.
Are Ocular Migraines Serious?
While ocular migraines can be distressing, they are generally not considered serious. However, it’s crucial to consult an eye specialist to rule out other potential causes of your symptoms. At Blue Fin Vision®, we provide comprehensive eye examinations to ensure your ocular health is thoroughly assessed.
Why Am I Suddenly Getting Ocular Migraines?
If you’re experiencing ocular migraines for the first time, several factors could be contributing to their sudden onset:
- Stress and Lifestyle Changes
Stress is a common trigger for ocular migraines. Recent changes in your work or personal life could be contributing to increased stress levels, potentially triggering these episodes.
- Hormonal Fluctuations
For women, changes in hormone levels due to menstruation, pregnancy, or menopause can trigger ocular migraines. If you’ve recently started or changed hormonal contraceptives, this could also be a factor.
- Environmental Factors
Changes in your environment, such as increased exposure to bright or flickering lights, loud noises, or strong odours, can trigger ocular migraines in susceptible individuals.
- Dietary Changes
Certain foods and drinks, including caffeine, alcohol, and foods containing nitrates or MSG, can trigger ocular migraines in some people. If you’ve recently changed your diet, this could be a contributing factor.
- Dehydration and Blood Sugar Fluctuations
Not drinking enough water or experiencing low blood sugar can potentially trigger ocular migraines. Ensuring proper hydration and maintaining stable blood sugar levels may help prevent episodes.
- High Blood Pressure
Uncontrolled hypertension can contribute to the occurrence of ocular migraines. If you’ve recently been diagnosed with high blood pressure or have stopped taking blood pressure medication, this could be a factor.
- Increased Screen Time
With many of us spending more time in front of digital screens, eye strain from prolonged screen use could be triggering ocular migraines.
Symptoms of Ocular Migraines
Recognising the symptoms of ocular migraines is crucial for proper diagnosis and treatment. Common symptoms include:
- Temporary vision loss or blindness in one eye
- Flashing or shimmering lights
- Zigzag patterns in your visual field
- Blind spots in your vision (scotomas)
These visual disturbances typically last between 5 to 30 minutes, rarely exceeding an hour. Remember, these symptoms persist even when the eyes are closed, a key diagnostic feature of ocular migraines.
How to Manage Ocular Migraines
If you’re experiencing ocular migraines, there are several steps you can take to manage your symptoms:
- Rest in a quiet, dark room: When experiencing an ocular migraine, find a calm environment to rest your eyes.
- Apply a cold compress: Placing a cold compress on your forehead can help alleviate discomfort.
- Stay hydrated: Ensure you’re drinking enough water throughout the day.
- Identify and avoid triggers: Keep a migraine diary to help identify potential triggers.
- Practice stress-management techniques: Engage in activities like meditation, yoga, or deep breathing exercises to reduce stress.
- Maintain a regular sleep schedule: Aim for 7-9 hours of sleep per night.
- Take regular breaks from screen time: Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds.
