title: Central retinal artery occlusion after phacoemulsification under peribulbar anaesthesia: Pathogenic hypothesis.
abstract: METHODS
  A 77-year-old patient had uneventful cataract surgery in the right eye under peribulbar anaesthesia. The next day, a severe and progressive eyelid swelling was noted, caused by an unknown allergic reaction to povidone-iodine. The allergic signs dissapeared by the fifth day, but amaurosis and a cherry-red spot were detected. Doppler ultrasound and CT angiography confirmed an 80% ipsilateral internal carotid artery stenosis.
  
  
  CONCLUSIONS
  Retinal vascular occlusion after orbital loco-regional anaesthesia is rare. When this complication occurs, carotid disease, and local or systemic factors, should be evaluated.
