title: [Clinical observation on removal of small foreign bodies touching the optic nerve in the deep orbital region].
abstract: OBJECTIVE
  To evaluate the treatment and therapeutic efficacy of extraction of deep intra-orbital little foreign bodies touching the optic nerve.
  
  
  METHODS
  In this retrospective study, the clinical data of 5 deep intra-orbital little foreign bodies cases were recorded from 2008 to 2012 in Eye Center, PLA 474th Hospital. The treatment and therapeutic effect were analyzed.
  
  
  RESULTS
  The properties of the foreigen bodies in these 5 cases weremetallic in 4 cases and nonmetallic in 1 cases. The preoperative visual acurity were no light perception in 3 cases, light perception in 1 case, and hand movement in 1 case. The complications included vitreous hemorrhage which had been temponaded with silicon oil in other hospital (1 case), traumatic cataract, retinal and choroid detachment (1 case), traumatic retinal detachment and vitreous hemorrhage (2 cases). In all the cases, computed tomography (CT) indicated deep orbital foreign bodies touching the optic nerve, and clinical manifestations showed optic nerve injuries. The Foreign bodies were extracted successfully in all the cases. The postoperative visual acuity improved in 3 cases, however 2 cases remained blind.
  
  
  CONCLUSIONS
  Carefully positioned with CT preoperatively, Deep intra-orbital little foreign bodies touching the optic nerve could be exctracted by lateral orbitotomy and the vision could improve in some patients.
