大阪市立大学における7年間の眼外傷の統計的検討

Review of ocular injuries during the foregoing seven years at Osaka City University

（展示192）　1989年から1995年までの7年間に，大阪市立大学眼科を受診した眼外傷患者606名625眼を対象に，統計的観察を行った。

　男女比は3.2：1で，年齢では10歳代が156眼（25.0％）と最も多く，原因では日常生活上の受傷が24.8％を占め，次にスポーツ外傷（19.7％）が多かった。病態は隅角後退が最も多く，ついで虹彩炎，角膜びらん，網膜振盪症であった。

　スポーツ外傷では野球およびサッカーが58.5％を占め，サッカーでは眼底上方，野球では眼底下方に病巣が発生する頻度が高かった。

　0.2以下の視力予後不艮例は76眼で，その原因はけんかや仕事中の受傷に多く，病態は眼内異物，網膜剥離，視神経萎縮が主であった。

We reviewed 625 eyes of 606 cases with ocular trauma seen by us during 7 years ending 1995. The series comprised 476 eyes in males and 149 eyes in females, or at the ratio of 3.2 to 1. Patients in the second decade of life formed the largest group at 25.0% of the series. The causes of trauma included accidents in daily life at 24.8% and sports-related activities at 19.7%. The most common type of eye injury was angle recession, followed by traumatic iritis, corneal erosion and retinal concussion in the descending order. Baseball and soccer injuries accounted for 58.5% of sports-related injuries. Injury by soccer ball was most commonly associated with lesion in the superior fundus sector. Injury by baseball frequently involved the inferior fundus sector. Impairment of visual acuity to 0.2 or less was present in 72 eyes. Injury to these eyes mainly resulted from fighting or professional work. Intraocular foreign body, retinal detachment and optic nerve atrophy indicated poor prognosis.
