開放性眼外傷の予後予測因子の検討

Prognostic factors in open injury to the eyeglobe

要約　目的：開放性眼外傷の視力転帰に関係する要因の報告。対象と方法：過去10年間に初回手術を行った眼外傷84例84眼を対象とした。男性71例，女性13例で，ほぼ全例が受傷当日に受診していた。The Ocular Trauma Classification Group（1997）に従って，外傷の到達部位，角膜穿孔創の大きさ，網膜剝離の有無の各因子を評価した。結果：今回の症例群では，作業中の受傷，男性，50歳台が多かった。最終視力の不良化要因は，受傷または到達部位が眼球の後方にあること，初診時視力が不良であること，角膜創が大きいこと，網膜剝離の併発であった。結論：開放性眼外傷の視力予後の推定には，Ocular Trauma Classification Groupの分類が有用である。

Abstract.　Purpose：To report prognostic factors in open injury to the eyeglobe. Cases and Method：This retrospective study was made on 84 eyes of 84 cases who were treated by us during the past 10 years. The series comprised 71 males and 13 females. Almost all the cases were treated on the same day of injury. Prognostic factors were analyzed based on classification by Ocular Trauma Classification Group（1997）regarding depth of injury,size of corneal injury,and presence of retinal detachment. Results：The present series was characterized by injury during work-related accidents and involvement of males in the sixth decade of life. Final visual acuity tended to be poor when the injury was located deeper in the eyeglobe,when corneal injury was greater than 1.5 mm,and when retinal detachment was present. Conclusion：Classification by Ocular Trauma Classification Group promises to be of value in assessing visual outcome in open injury to the eyeglobe.
