Understand Ocular Migraines
Ocular migraines may sound painful, but they typically are not. While people who experience migraines often feel significant pain, they are also more likely to experience ocular migraines, which can act as a precursor to a migraine. However, ocular migraines can also occur on their own, without leading to a headache. Migraines with auras are also common, where people experience visual disturbances—often seen as squiggly lines or glowing halos—alongside the migraine.
What Are Ocular Migraines?
Ocular migraines are visual disturbances that can affect one or both eyes. These disturbances often appear as “hallucination” type visuals, similar to the auras associated with migraines with aura, and usually last for a short period. In some cases, people may experience partial or complete vision loss in the affected eye. If you experience these symptoms, it’s important to inform your optometrist, as transient vision loss can indicate other underlying conditions that may need further evaluation.
Causes and Treatment of Ocular Migraines
The exact cause of ocular migraines remains unclear, as they are difficult to study. They are believed to result from disruptions in blood flow to the optic nerve and retina. When normal blood circulation is interrupted, it affects how the retina and optic nerve function, leading to visual disturbances. The reason behind these changes in blood flow is still unknown. There are no specific treatments or medications to speed up the resolution of ocular migraines. They typically go away on their own within a certain time frame. If you experience one while driving or performing tasks that require clear vision, it’s best to stop what you’re doing and wait for the episode to pass.
