Purpose
To evaluate the efficacy of vitreous surgery for treatment of fundus damages caused by ocular blunt trauma.
Methods
Clinical records were reviewed retrospectively for a series of consecutive 101 patients (105 eyes) with fundus damages caused by ocular blunt trauma underwent vitreous surgery from October 1992 to March 1998．
Results
Based on clinical examination and findings during surgery,all cases were divided into 4 subgroups:vitreous hemorrhage(VH)in 23 yes,VH with retinochoroidal rupture or optic damage in 25 eyes,traumatic retinal detachment in 46 eyes,and retinal giant tear in 11 eyes.Vision acuity improvement achieved in 77 eyes(73.3%)and of them 69 eyes(65．7%)had 0.02～0．6with 38 eyes(55．0%)better than 0．1.Two eye s with no light perception obtained better than 0.1． Visual acuity remained unchanged in 26 eyes(24.8%)and 2 eyes(1.9%)became worse after operation．The retina reattached in 54 eyes(94.7%).
Conclusion
Severe ocular blunt trauma may cause visual impairment and various fundus damages.Appropriate vitreous surgery can salvage most eyes with those injuries.
