title: Central retinal artery occlusion in association with an aneurysm of the internal carotid artery.
abstract: OBJECTIVE
  To report an unusual case of central retinal artery occlusion in a 41-year-old woman.
  
  
  METHODS
  Interventional case report.
  
  
  METHODS
  A 41-year-old woman presented with sudden and painless decrease of visual acuity of the left eye. Indirect ophthalmoscopy revealed the typical fundus findings of a central retinal artery occlusion. The fovea was spared by a cilioretinal arteriole.
  
  
  RESULTS
  Cerebral angiography showed an aneurysm of the left internal carotid artery, measuring approximately 1.7 x 1.5 x 1.7 cm. The aneurysm was located in close proximity to the ophthalmic branch.
  
  
  CONCLUSIONS
  Aneurysm of the intracranial arteries should be included in the differential diagnosis of central retinal artery occlusion in young patients.
