Are you someone who suffers from migraines? If so, you’re probably familiar with some of the uncomfortable symptoms they can bring, such as throbbing headaches, nausea, and sensitivity to light and sound. However, another common symptom that often accompanies migraines is changes in vision. These visual disturbances, known as migraine aura, can be both perplexing and alarming. In this article, we will explore the relationship between migraines and vision changes, shedding light on why they occur and what you can do to manage them.
Overview
Migraine and vision changes often go hand in hand. A migraine is a neurological disorder that causes intense headaches, and vision changes are a common symptom experienced by many individuals during a migraine episode. These visual disturbances are known as migraine-related vision changes or ocular migraines. While they may be unsettling, it’s important to understand that they are typically temporary and harmless. By learning more about the different types, common symptoms, causes, diagnosis, treatment options, coping strategies, and when to seek medical attention, you can effectively manage this aspect of your migraine condition.
What is a migraine?
A migraine is a type of recurring headache that is often accompanied by a range of other symptoms. It is believed to be a neurological disorder involving abnormal brain activity. Migraines are characterized by intense, throbbing pain that can last for several hours or even days. The exact cause of migraines is still not fully understood, but certain triggers and genetic factors are believed to play a role.
What are vision changes?
Vision changes, also referred to as aura, are a common symptom experienced by individuals with migraines. These visual disturbances can range from mild to severe and can affect one or both eyes. Vision changes during a migraine episode can include flashing lights, blind spots, zigzag lines, shimmering or colored lights, and blurry or distorted vision. They typically last for about 20 minutes to an hour, but can sometimes persist for longer. It’s important to note that vision changes can occur with or without a headache.
Types of Migraine-related Vision Changes
Migraine with aura
Migraine with aura is a type of migraine where visual disturbances occur before or during the headache phase. These aura symptoms are usually experienced as temporary visual disturbances, such as seeing flashing lights, zigzag lines, or blind spots. However, aura can also manifest as other sensory disturbances, such as tingling or numbness in the face or hands. Migraine with aura is believed to affect about 25% of people with migraines.
Visual aura without headache
Some individuals may experience aura symptoms without the subsequent headache. This is known as visual aura without headache. While it can be puzzling to experience visual disturbances without the accompanying pain, it is still considered a form of migraine and may be a warning sign of an impending headache episode.
Retinal migraine
Retinal migraine, also known as ocular migraine, is a rare form of migraine that primarily affects vision in one eye. During a retinal migraine episode, vision loss or blindness can occur in the affected eye for a short period, usually less than an hour. This type of migraine is often accompanied by a migraine headache.
Ocular migraine
Ocular migraine refers to visual disturbances that affect both eyes simultaneously. It typically causes temporary vision loss or blind spots that can last for minutes or even hours. While ocular migraine does not usually cause severe pain, it can be a warning sign of an impending migraine headache.
Common Symptoms of Migraine-related Vision Changes
Flashing lights
Flashing lights, also known as photopsia, are a common visual symptom experienced during a migraine episode. These flashes of light may appear as streaks, dots, or sparkles and can be persistent or intermittent. They are often described as similar to seeing stars or fireworks.
Blind spots
Blind spots, also referred to as scotomas, are areas of reduced or lost vision that can occur during a migraine episode. These blind spots can vary in size and shape and may appear as patches of darkness or grayness in the visual field. They can be stationary or can move around, causing further confusion and discomfort.
Zigzag lines
Zigzag lines, also known as fortification illusions, are a distinct visual symptom experienced by some individuals with migraines. These lines may appear as shimmering or jagged patterns that expand in a zigzag shape. They can move across the visual field and are often accompanied by other aura symptoms.
Shimmering or colored lights
Shimmering or colored lights are another visual phenomenon often seen during a migraine episode. These lights can appear as flickering or pulsating sensations of various colors, including white, yellow, or even bright pink. They can be distracting and may interfere with daily activities.
Blurry or distorted vision
Blurred or distorted vision is a common complaint among individuals experiencing migraine-related vision changes. This can manifest as difficulty focusing, double vision, or a general reduction in visual acuity. It may feel as if you are looking through a foggy or distorted lens, making it challenging to perform tasks that require precise visual perception.
Causes of Migraine-related Vision Changes
Vascular changes in the brain
Migraine-related vision changes are believed to be caused by vascular changes in the brain. During a migraine episode, blood vessels in the brain may constrict and then dilate, leading to changes in blood flow. These fluctuations in blood flow can affect the visual cortex, causing the visual disturbances experienced during a migraine.
Genetic factors
There is evidence to suggest that genetics play a role in the development of migraines and the associated vision changes. If you have a family history of migraines, you may be more likely to experience these visual symptoms. Researchers have identified certain genes that may increase the susceptibility to migraines and aura symptoms.
Hormonal changes
Hormonal fluctuations are known to trigger migraines in some individuals, particularly women. Changes in estrogen levels, such as those that occur during the menstrual cycle, pregnancy, or menopause, can increase the likelihood of experiencing migraines and associated vision changes. This hormonal influence is thought to affect the vascular system and the brain’s response to pain.
Triggers
Various triggers can precipitate migraine episodes and the accompanying vision changes. These triggers can differ among individuals but commonly include certain foods (such as chocolate, cheese, or caffeine), sensory stimuli (such as bright lights or loud noises), hormonal changes, stress, lack of sleep, and weather changes. By identifying and avoiding triggers, you may be able to reduce the frequency and intensity of your migraines.
Diagnosing Migraine-related Vision Changes
Medical history and physical examination
Diagnosing migraine-related vision changes typically involves a comprehensive medical history review and physical examination. Your healthcare provider will inquire about your symptoms, including the frequency, duration, and characteristics of your migraines. They will also ask about any family history of migraines and conduct a thorough assessment of your overall health.
Eye examination
An eye examination is an essential part of diagnosing migraine-related vision changes. Your eye doctor will assess your visual acuity, perform various tests to evaluate your eye health, and check for any abnormalities or signs of underlying conditions that may be contributing to your visual symptoms. This examination will help rule out other potential causes of vision changes.
Neurological examination
Since migraines are a neurological condition, a neurological examination may be conducted to assess brain function and rule out other neurological disorders. This examination may involve assessing reflexes, muscle strength, coordination, and sensory perception.
Other diagnostic tests
In some cases, additional diagnostic tests may be ordered to assist in the diagnosis of migraines and ruling out other conditions. These tests may include magnetic resonance imaging (MRI) or computed tomography (CT) scans to evaluate the brain and rule out any structural abnormalities or other underlying causes of your symptoms.
Treatment Options for Migraine-related Vision Changes
Medications for acute episodes
To manage migraine-related vision changes and associated headaches, various medications can be utilized. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen sodium, can help alleviate pain and reduce inflammation during a migraine episode. Triptans are a class of medications specifically designed to treat migraines by constricting blood vessels and inhibiting the release of pain-causing substances.
Preventive medications
If your migraines are frequent or significantly impacting your quality of life, your healthcare provider may recommend preventive medications. These medications are taken regularly to reduce the frequency and intensity of migraine episodes. These include beta-blockers, calcium channel blockers, antidepressants, and anti-seizure medications. The choice of preventive medication will depend on your specific symptoms and medical history.
Lifestyle changes
In addition to medications, certain lifestyle changes can help manage migraine-related vision changes. It is important to establish a regular sleep routine, aiming for consistent sleep patterns and getting an adequate amount of sleep each night. Regular exercise and maintaining a healthy diet can also contribute to migraine prevention. Identifying and avoiding triggers, such as certain foods, stressful situations, and sensory stimuli, can greatly reduce the frequency and severity of your migraines.
Alternative therapies
For some individuals, alternative therapies may provide additional relief and complement conventional treatments. These may include acupuncture, biofeedback, relaxation techniques, and cognitive-behavioral therapy. However, it is important to consult with your healthcare provider before initiating any alternative therapies to ensure they are safe and suitable for your specific condition.
Coping Strategies for Migraine-related Vision Changes
Rest and relaxation
When experiencing migraine-related vision changes, it is crucial to prioritize rest and relaxation. Find a quiet, dark place to rest and apply a cold or warm compress to your head or neck, depending on what provides relief. Taking a break from screens and minimizing sensory stimulation can also help alleviate symptoms.
Managing triggers
Identifying and managing triggers can significantly reduce the frequency and intensity of migraines. Keep a migraine diary to track your symptoms and potential triggers, such as certain foods, environmental factors, or stressors. Once you have identified your triggers, make a conscious effort to avoid or minimize exposure to them.
Stress management techniques
Stress is a common trigger for migraines, so incorporating stress management techniques into your daily routine can be beneficial. Explore relaxation techniques such as deep breathing exercises, meditation, mindfulness, or yoga. Engaging in hobbies or activities that you enjoy can also help reduce stress levels.
