title: Ophthalmic artery microcatheterization for research purposes in pigs. A technical note.
abstract: OBJECTIVE
  To describe a technique for micro catheterization of the external ophthalmic artery (EO) in pigs for investigational and training purposes.
  
  
  METHODS
  Carotid angiography was performed in seven male domestic pigs. The external ophthalmic artery was reached with a microcatheter in order to administer a neoplastic drug in the eye.
  
  
  RESULTS
  The external ophthalmic artery could be found arising from the infraorbital (IO) artery in the bend of the internal maxillary (IM) artery. It could be reached in every animal.
  
  
  CONCLUSIONS
  Following anatomic landmarks of the external carotid (EC) artery the ophthalmic artery can be easily reached and catheterized for training and investigational purposes.
