Ocular migraines involve unique visual disturbances, often affecting one eye. Understanding these symptoms is crucial for effective management and treatment.
An ocular migraine, sometimes called a retinal migraine, is a rare migraine type that brings on visual disturbances in one eye. The condition is not caused by an issue in the eye itself but rather by the way the brain processes signals from the eyes. Understanding ocular migraines is important because even temporary vision changes can be unsettling and warrant proper evaluation by our eye doctors.
An ocular migraine is a unique form of migraine headache marked by vision changes in one eye, such as blind spots, shimmering lights, or zigzag patterns. The symptoms occur because of abnormal neurological activity rather than a primary eye disease. If you notice that these visual disturbances continue even when you close your eyes, it suggests the trigger is in your brain and not an eye problem.
It’s easy to get confused between an ocular migraine and a migraine with aura. The key difference lies in the area affected: while migraine auras typically disrupt the vision in both eyes, ocular migraines tend to present in just one eye. This distinction is essential for our eye doctors as they work to determine the underlying cause of your symptoms. Even though the visual disturbances might resemble each other, knowing which type you’re experiencing can shape how your condition is managed and monitored.
Ocular migraine symptoms are primarily related to changes in your vision, and recognizing these early signs can make a significant difference. The visual symptoms typically last anywhere from 5 to 60 minutes, with your vision gradually returning to its normal state once the episode clears. Here’s what you might experience during an ocular migraine:
It’s important to note that not everyone will experience all of these symptoms, and the severity can vary from person to person. Even if you only notice one or two signs, it’s wise to have your symptoms evaluated by our eye doctors.
While the hallmark of an ocular migraine is the visual disturbance in one eye, many individuals also experience a headache. The headache may develop before, at the time of, or following the visual symptoms, typically manifesting as a throbbing or pulsing pain behind the affected eye. You might also have sensitivity to light, noise, or even certain smells. In addition to head pain, other common associated symptoms include:
Even though the headache can vary in intensity, these symptoms usually resolve once the ocular migraine subsides. However, if you experience unusually severe or prolonged symptoms, contacting our office for personalized advice is always a wise precaution.

The exact causes of ocular migraines remain a topic of ongoing research. Experts believe that several factors may contribute to these visual disturbances by affecting blood flow or nerve activity. One popular theory is that spasms in the retinal blood vessels can temporarily reduce blood flow, leading to the visual symptoms observed during an episode. This sudden change in blood flow is thought to play a role in triggering the cascade of neurological events that result in an ocular migraine.
Another theory revolves around the notion that certain nerve pathways in the brain become overstimulated, which then sends abnormal signals to the eye. Since the visual cortex in the brain is highly sensitive, even minor fluctuations in its activity can trigger significant visual disturbances. Genetics may also be at play here—studies suggest that up to 50% of those who experience ocular migraines have a family history of the condition, indicating that a predisposition might be inherited.
Ocular migraines, much like other types of migraines, often occur in response to specific triggers. These triggers can vary significantly from one person to another, so keeping track of events that preceded your ocular migraine is crucial. Some of the most commonly reported triggers include:
Since not everyone is affected by the same triggers, maintaining a detailed diary of your migraine episodes can aid our eye doctors in identifying patterns that may help you prevent future occurrences.
Because there’s no single test that definitively diagnoses an ocular migraine, our eye doctors take a comprehensive approach. They begin by asking about your specific symptoms, their duration, and any patterns you have noticed over time. Your personal and family medical histories are important pieces of the puzzle, and discussing them openly helps our eye doctors rule out other potential causes. When necessary, you might also be referred for additional tests to ensure that no other eye or neurological condition is at work—especially because similar symptoms can sometimes indicate more serious issues.
During a physical exam, our eye doctors may use instruments such as an ophthalmoscope to check for any visible changes in the blood flow or structure of your retina. Even though the visual symptoms of ocular migraines are usually temporary, this thorough evaluation is crucial to ensure proper management and to rule out conditions like amaurosis fugax, retinal artery issues, or other vascular problems.
Because vision changes can arise from various conditions, differentiating an ocular migraine from other, more serious conditions is essential. Some conditions that may present with similar symptoms include:
If your symptoms are new or have changed in intensity or frequency, it’s particularly important to schedule an evaluation with our eye doctors. Early diagnosis and management can help rule out dangerous conditions and guide you toward effective treatment strategies.
