I．緒言

　眼外傷に関する多数の報告の中で，片側の眼外傷が他側の視野狭窄をもたらした症例は，私の調べた範囲では僅かに籾木氏の1例あるのみである。氏は，木片に依る右眼球眼窩刺創患者を受傷後33日目に初めて診察した所，右眼は失明し，左眼の視野が黄斑回避を有する耳側半盲を示したと述べている。最近私は，飛来せる棒状木片の先端が，眼瞼を損傷することなく，瞼裂を経て右眼球眼窩を挫滅し，受傷後8ヵ月有余にして左眼の視力低下や，高度の求心性視野狭窄，著明な眼精疲労等を現わした1例を経験したのでここに報告する。

A man of 38 years, when working at a saw mill, had his right bulb and orbit stabbed with a piece of timber of 150cm in length and 1×2cm² in sectional width, penetrating st-raight 7.5cm deep through the palpebral fissure without injuring the lids.

X-ray photograph showed a partial defect in the lower wall of the Fissura orbitalis superior.

Enucleatio bulbi and removal of the intraorbital foreign bodies were performed.

Afrer 8 months the patient complained of fogginess and fatigued vision. By examination were finded medium disturbance of vision and concentric contraction of the visual field of the left eye.
