“Ocular Migraine” is a term that has been used to refer to a number of migraine subtypes that are characterized by a variety of visual disturbances including visual loss, blind spots, zig-zag lines, or seeing stars.
Unlike other forms of migraine, they may occur without any accompanying head pain. It’s not uncommon for a single patient to experience a wide range of visual symptoms.
Like other types of migraine, harsh lights and electronic screens can be triggers. Straining your eyes by staring at a screen for long periods of time, spending time in fluorescent or another harsh lighting, driving long distances and other taxing visual activities can increase your risk for attacks.
Talk to your eye doctor about how to avoid attacks.
