徳島県における過去10年間の開放性眼外傷の検討

A ten-year review of open-globe injury in Tokushima Prefecture

要約　目的：開放性眼外傷の統計報告。対象：2011年までの10年間に徳島大学病院と徳島赤十字病院で手術をした開放性眼外傷90例91眼を対象とした。結果：男性55例，女性35例で，年齢は3～99歳（平均62歳）であった。症例の内訳は，眼球破裂42眼（46％），眼球穿孔49眼（54％）であった。穿孔は裂傷29％，眼内異物23％，二重穿孔2％であった。平均年齢は眼球穿孔が48歳，眼球破裂が77歳で，有意差があった（p＜0.01）。眼球破裂の原因は転倒が多かった。眼球破裂で硝子体手術が行われた6眼では，0.5以上の矯正視力が得られた。結論：眼球破裂では硝子体手術により視力転帰が改善することがある。

Abstract.　Purpose：To present a review of open-globe injury in Tokushima Prefecture. Cases：This review was made on 91 eyes of 90 cases who were surgically treated at Tokushima University Hospital or Tokushima Red Cross Hospital during 10 years through 2011. Results：The series comprised 55 males and 35 females. The age ranged from 3 to 99 years, average 62 years. There were 42 eyes（46％）of eyeglobe rupture and 49 eyes（54％）of eyeglobe perforation. Cases of perforation included penetrating trauma 29％, intraocular foreign body 23％, and double perforation 2％. The age averaged 48 years in cases of perforation and 77 years in those of eyeglobe rupture. The difference was significant（p＜0.01）. Falling down was the most frequent cause of eyeglobe rupture. Corrected visual acuity of 0.5 or over was obtained in 6 eyes that received vitreous surgery after eyeglobe rupture. Conclusion：Vitreous surgery may result in favorable visual outcome following eyeglobe rupture.
