術後視力良好な穿孔性眼外傷における受傷要因の検討

Factors related to fair visual outcome in perforating ocular injury

要約　目的：術後視力良好な穿孔性眼外傷における受傷要因を解析した。対象と方法：横浜市立大学附属病院に過去5年間に受診した穿孔性眼外傷22例22眼（男性18例，女性4例，平均年齢35歳）を術後最終視力によってA群（術後最終視力1.0以上の症例），B群（術後最終視力1.0未満の症例）と分類し，両群の術前視力，年齢，受傷時間，受傷時の就労有無，自他傷の別，受傷方法（飛入，刺入），受傷異物（釘，針金，鉄片，その他）について検討した。結果：A群とB群では釘の受傷の有無で統計学的に有意差があった。結論：穿孔性眼外傷では釘のような直線状で不整な形状でない異物の受傷であれば視力予後が良好である可能性がある。

Abstract.　Purpose：To analyze cases of perforating ocular injury with fair visual outcome. Cases and Method：This retrospective study was made on 22 eyes of 22 cases who were treated by for perforating ocular injury in the past 5 years. The series comprised 18 males and 4 females. The age ranged from 3 to 66 years,average 35 years. Cases were divided into 2 groups consisting of 11 eyes each. One group had final visual acuity of 1.0 or better. The other had visual acuity of less than 1.0. Cases were evaluated regarding initial visual acuity,age,circumstances during injury,and causative object. Results：Final visual acuity was better when injured by a not ragged object including a nail（p＜0.05）. Conclusion：Visual outcome is better when injured by a not irregularly shaped object like a nail.
