術前に裂創不明の眼球破裂眼の裂創に対する検討

Review of eyeglobe rupture with no detectable wound before surgery

要約　目的：術前に裂創が不明であった眼球破裂11眼の報告。対象と方法：過去5年間に治療した眼球破裂眼のうち，術前に裂創が不明であった11例11眼を診療録の記録により検索した。結果：男性4例，女性7眼で，年齢は58～95歳（平均79歳）であった。受傷原因はすべて鈍性外傷で，手術により全例に1個の眼球破裂創があった。裂創の中心は，9眼では上方にあり，他の2眼でも裂創の一部は上方に含まれていた。結論：術前に裂創が不明な眼球破裂眼では，裂創が必ず存在し，その中央部または一部が上方に位置する。このような症例では，手術の開始時に上方結膜下の裂創を確認することが有用である。

Abstract.　Purpose：To report the location of scleral wound in ruptured eyeglobes with no identifiable wound before surgery. Cases and Method：This retrospective study was made on 11 eyes of 11 patients treated by us in the past 5 years. All the eyes had eyeglobe rupture with no identifiable wound before surgery. Results：The series comprised 4 males and 7 females. The age ranged from 58 to 95 years,average 79 years. Injury was due to blunt trauma in all cases. During surgery,all the eyes had one scleral wound. Center of the wound was located superior to horizontal line running through 9 and 3 o'clock position in 9 eyes. In the remaining 2 eyes,a part of the wound lay superior to the line. Conclusion：A scleral wound was present in all ruptured eyes during surgery. The wound was located in the superior hemisphere of the globe. This finding may serve as a guideline in the surgery on ruptured eyeglobe with no identifiable wound.
