title: CONTRALATERAL ANESTHESIA IN TWO PATIENTS AFTER RETROBULBAR BLOCK.
abstract: OBJECTIVE
  To report a case series of two patients with contralateral anesthesia after retrobulbar block.
  
  
  METHODS
  Retrospective review of two cases and review of the literature.
  
  
  RESULTS
  Two patients of one practitioner received contralateral anesthesia after retrobulbar block for posterior segment surgery. Patient 1 suffered from transient contralateral akinesia, whereas Patient 2 experienced transient contralateral amaurosis.
  
  
  CONCLUSIONS
  Posterior spread of anesthetics is a rare but potentially serious complication of retrobulbar anesthesia caused by spread of anesthetics along the optic nerve sheath. Modification of injection technique can decrease the risk of this complication.
