title: Photophobia as the visual manifestation of chiasmal compression by unruptured anterior communicating artery aneurysm. Case report.
abstract: A 37-year-old woman presented with photophobia without visual loss associated with chiasmal compression by an unruptured anterior communicating artery (AcomA) aneurysm. She had suffered progressive photophobia for one year. Neuroimaging indicated an AcomA aneurysm attached to the chiasm. Photophobia was resolved following clipping of the aneurysm. AcomA aneurysm should be considered in patients who experience photophobia without visual loss.
