What is Ophthalmic Migraine?
Ophthalmic migraine, also called visual migraine, is a type of migraine that primarily affects vision. It is characterized by transient visual disturbances that may precede or accompany a headache. Unlike other migraines, the visual symptoms are usually temporary and reversible, but they can be alarming and may interfere with daily activities such as reading, driving, or using a computer. Ophthalmic migraines are more common in adults, particularly in women, and may have a hereditary component.
Aura
The aura in ophthalmic migraine is a set of visual symptoms that usually occurs before the onset of headache. Common aura manifestations include flashing lights, zigzag lines, shimmering spots, blind spots (scotomas), or tunnel vision. Auras generally develop gradually over 5–20 minutes and last less than an hour, often resolving completely without any residual vision loss.
The visual aura reflects cortical spreading depression—a wave of electrical activity followed by temporary suppression in the brain’s visual cortex. Recognizing aura is important because it helps differentiate ophthalmic migraine from other conditions like retinal migraine or ocular ischemic events. Some patients may experience aura without subsequent headache, a variant called acephalgic migraine.
Symptoms
Symptoms of ophthalmic migraine extend beyond visual disturbances. Patients often report temporary blurred vision, eye pain, light sensitivity (photophobia), nausea, or dizziness. Headache, if present, is usually throbbing and affects one side of the head, though some patients experience minimal or no headache.
Additional symptoms may include tingling in the face or extremities, difficulty concentrating, or mood changes. Symptoms are typically short-lived, lasting from a few minutes up to an hour, and resolve without permanent damage. Careful documentation of symptom onset, duration, and characteristics can assist healthcare providers in confirming the diagnosis and excluding other causes.
Treatment
Treatment of ophthalmic migraine focuses on symptom relief and prevention. Acute attacks can be managed with rest in a dark room, hydration, and over-the-counter pain relievers such as NSAIDs. Prescription medications, including triptans, may be used in patients with frequent or severe attacks.
Preventive strategies are essential for recurrent cases. Lifestyle modifications like adequate sleep, regular meals, stress management, and avoiding known triggers (such as bright lights, certain foods, or hormonal changes) can reduce attack frequency. In some patients, preventive medications such as beta-blockers, calcium channel blockers, or anticonvulsants may be recommended.
Intractable Type
Intractable ophthalmic migraine refers to cases where attacks are frequent, prolonged, or resistant to standard treatments. Patients may experience persistent visual disturbances, chronic headaches, or significant impact on daily functioning. This type often requires referral to a neurologist or headache specialist for advanced management.
Treatment options may include combination therapy, higher doses of preventive medications, or newer agents such as CGRP inhibitors. Intractable cases also benefit from careful monitoring of triggers, structured headache diaries, and comprehensive lifestyle interventions. Early recognition is key to prevent complications like medication overuse headaches.
Ophthalmic Migraine vs Ocular Migraine
While the terms are sometimes used interchangeably, there are subtle differences. Ophthalmic migraine primarily refers to visual symptoms originating from the brain’s visual cortex, whereas ocular migraine (or retinal migraine) involves transient vision loss in one eye, typically due to retinal or ocular vascular changes. Ocular migraines are less common and may be associated with higher risk of vascular events.
In ophthalmic migraine, visual disturbances usually affect both eyes and may present as flashing lights, zigzags, or blind spots. In contrast, ocular migraine affects only one eye, often as a temporary dark spot or vision loss. Differentiating these conditions is critical for management, as ocular migraine may require ophthalmologic or cardiovascular evaluation to rule out serious causes.
