Whenever the word “migraine” is used, people often think of a “bad headache”. There is however, something called an “ocular migraine”, which is painless. The patient with the ocular migraine usually experiences a visual “aura” similar to that of a classic migraine, but without the subsequent headache. There are several visual symptoms that can occur. Patients will come into our office describing a large blind spot in their central vision with flashing or flickering lights. Others will describe wavy or zig-zag lines and some experience a kaleidoscopic effect. Ocular migraines typically last approximately 20-30 minutes and its causes can be similar to those of a classic migraine headache. Many of these symptoms include certain smells, bright lights, fatigue and emotional stress. If you experience any of the visual symptoms of an ocular migraine, it is recommended to have a complete eye health examination to rule out any other possible causes.
