片頭痛と光環境

抄録

Photophobia in migraine is a symptom with a dazzling light sensibility such as sun and room lighting at the time of headache attack, and the light may also cause headache attack. This paper proposes an optimal light environment for patients with migraine. It is pointed out that intrinsically photosensitive retinal ganglion cells for non-image-forming vision could be involved in the mechanism for photophobia of migraine as visual information from retina. The light environment suitable for patients with migraine can be low color temperature and low illuminance and should avoid the higher light component of blue light. Adjustment of the light environment for light-sensitive patients with migraine might possibly reduce headache attack.
