眼外傷症例の視力予後不良因子の検討

Factors related to visual outcome in ocular injury

要約　目的：眼外傷症例の予後不良因子の検討。対象と方法：対象は2009～2011年に，眼外傷で獨協医科大学眼科を受診し，入院加療を要した71例71眼。眼外傷症例の患者因子や病態（年齢，術前視力，病態，角膜穿孔，前房出血，水晶体損傷，水晶体または眼内レンズ脱臼・脱出，硝子体出血，硝子体脱出，網膜剝離，眼手術既往）と術後視力の関係をレトロスペクティブに解析した。結果：術後視力不良因子は，年齢60歳以上，術前視力0.01未満，眼球破裂，水晶体または眼内レンズ脱臼・脱出の合併，眼手術既往であった。結論：高齢者，術前視力不良，眼球破裂，水晶体または眼内レンズ脱臼・脱出，眼手術既往のある眼外傷症例の視力予後は不良である。

Abstract.　Purpose：To report factors that affect visual outcome in ocular injury. Cases and Method：This retrospective study was made on 71 eyes of 71 cases who were treated by us during 3 years through 2011. They were analyzed regarding age, visual acuity before treatment, nature of injury, corneal laceration, hyphema, injury to the lens including dislocation, vitreous hemorrhage or prolapse, retinal detachment, and history of eye surgery. Results：Visual outcome was significantly poor in patients aged 60 years or over, initial visual acuity less than 0.01, eyeglobe rupture, lens dislocation, and previous eye surgery. Conclusion：There are factors that affect the visual outcome in ocular injury. They include advanced age, poor visual acuity before treatment, eyeglobe rupture, lens dislocation, and previous eye surgery.
