Signs Of A Hemiplegic Migraine

Double Vision

Double vision is one of the many types of visual disturbances that occur with hemiplegic and other types of migraines. Visual problems are generally part of the aura that comes before the headache. In addition to double vision, patients have reported seeing zigzag lines, sparkles or shimmers, dots, flashing lights, and even blind spots in their vision. Between thirty to seventy-nine percent of patients may also experience nystagmus, which is very rapid, rhythmic eye movements that are completely involuntary. These visual changes are frequently accompanied by a sensitivity to light that can be extreme. Like other aura symptoms, vision changes can start slowly and build over the course of thirty minutes or longer, lasting for up to a few hours before disappearing. While apatient's vision typically returns to normal, in some rare instances, long-term problems can occur such as involuntary eye movements, have been documented.
