AB Nearly  3%  off  all  visits  to  emergency  departments  in  the  United  States  involve  ocular  complaints.  Bedside  ultrasound  has  become  an  indispensable  tool  for  both  traumatic  and  nontraumatic  eye  complaints.  While  ocular  ultrasonography  is  not  a  new  concept,  its  application  in  the  critical  care  setting  is  new.  Traditional  fundoscopic-based  eye  exams  are  not  only  difficult  to  perform  in  the  acute  care  setting;  they  are  notoriously  unreliable  in  the  setting  of  trauma.  The  physical  exam  of  the  eye  requires  controlled  conditions  and  appropriate  equipment  not  often  found  in  the  ICU.  Intensivists  can  use  familiar  ultrasound-based  principles  to  develop  a  limited  ocular  exam  capable  of  ascertaining  a  rage  of  pathological  conditions  not  previously  detectable  on  a  physical  exam.  The  eye  itself  is  a  fluid-filled  structure  ideal  for  sonographic  imaging.  The  use  of  ultrasound  allows  the  provider  to  perform  a  detailed  exam  of  the  ocular  structures  without  the  patient  opening  his  or  her  eyes.  This  limited  sonographic  exam  allows  the  practitioner  to  evaluate  ocular  movement,  the  anterior  chamber,  the  posterior  chamber,  and  the  retrobulbar  space,  including  the  optic  sheath  to  assess  intracranial  pressure.
