title: [The surgical timing and effects for vitreous hemorrhage caused by ocular blunt trauma].
abstract: OBJECTIVE
  To investigate the surgical timing and effects for vitreous hemorrhage caused by blunt ocular trauma.
  
  
  METHODS
  116 eyes of vitreous hemorrhage caused by ocular blunt trauma were divided into two groups, non-vitrectomy group (46 eyes) and vitrectomy group (70 eyes). The treating results and follow-up results were compared.
  
  
  RESULTS
  50 of 70 eyes (71.4%) in vitrectomy group and 10 of 46 eyes (21.7%) in non-vitrectomy group achieved a visual acuity of 0.1 or better over a follow-up period of 1 month, which indicated a significant difference between two groups. In the non-vitrectomy group, visual acuity of 10 eyes were better than 0.1, 7 eyes (70.0%) of them improved within 2 weeks of injury. In surgery group, 27.1% underwent only vitrectomy and 70.9% needed combining with other manipulations. In vitrectomy group the retina detachment was found in 3 eyes (4.3%) post-operatively and were cured by second operation. In non-vitrectomy group, the retinal detachment was found in 14 eyes (30.4%) during the follow-up period, and 8 eyes (72.7%) of 11 eyes received operation were cured.
  
  
  CONCLUSIONS
  Early vitreous surgery can improve curative effect for vitreous hemorrhage caused by blunt ocular trauma when no improvement was observed after applied drugs 2 - 3 weeks.
