title: [Combined central retinal artery and vein occlusion secondary to cataract surgery in a patient with persistent hyaloid artery].
abstract: METHODS
  A 72 year-old woman referred for cataract surgery in her right eye. Biomicroscopy revealed a retrocapsular fibrotic tissue in communication with the optic nerve, suggesting a persistent hyaloid artery (PAH). A posterior capsule rupture unexpectedly occurred during lens hydrodissection. One day after surgery, fundus examination showed a combined central retinal artery and vein occlusion.
  
  
  CONCLUSIONS
  PAH is uncommon, but its presence may alert us of this possible complication during cataract surgery.
