Ocular migraines, also known as retinal migraines, are a type of migraine that affects the vision. They are characterized by a sudden onset of visual symptoms, such as flashing lights, blind spots, or zigzag lines. The visual symptoms typically last for 5 to 60 minutes, and they may be followed by a headache.
Ocular migraines are not as common as other types of migraines, but they can be just as debilitating. They can cause significant visual disturbances, and they can make it difficult to see. In some cases, ocular migraines can even lead to temporary blindness.
What Causes Ocular Migraines?
The exact cause of ocular migraines is not fully understood, but they are thought to be caused by a temporary interruption of blood flow to the retina. The retina is the light-sensitive tissue at the back of the eye. When blood flow to the retina is interrupted, it can cause the visual symptoms of an ocular migraine.
