AB KEY  POINTSMechanical  trauma  to  the  eye  is  divided  into  open  globe  injury,  where  the  sclera  and/or  cornea  (eyewall)  have  a  full-thickness  wound,  and  closed  globe  injury,  where  these  structures  do  not  have  a  full  thickness-injury.The  six  extraocular  muscles  are  attached  directly  to  the  sclera,  which  is  covered  by  the  thin  clear  conjunctiva,  which  itself  terminates  at  the  cornea.In  the  patient’s  history,  posttrauma  floaters  and  a  visual  field  defect  are  highly  suggestive  of  a  retinal  detachment.When  trying  to  measure  vision  between  1/200  and  20/20,  the  patient  should  be  wearing  his  or  her  eyeglasses.The  pupil  may  be  peaked  if  the  iris  is  sealing  (plugging)  a  corneal  or  anterior  scleral  laceration.Computed  tomography  imaging  is  used  to  evaluate  orbital  fractures,  orbital  foreign  bodies,  and  intraocular  foreign  bodies.After  the  application  of  appropriate  medication,  corneal  abrasions  heal  faster  without  patching.Prior  to  consultation  with  an  ophthalmologist,  routine  treatment  for  a  hyphema  can  be  initiated  with  topical  steroid  eye  drops  four  times  a  day  and  a  topical  cycloplegic  agent.Intraocular  foreign  bodies  are  associated  with  an  increased  incidence  of  endophthalmitis  that  results  in  poorer  visual  outcomes  after  penetrating  injury.One  of  the  signs  of  an  orbital  floor  fracture  is  decreased  skin  sensation  on  the  cheek  of  the  affected  side.
