Two children recovered vision after penetrating injury of the orbit by wood had produced sudden blindness. Absent light perception demands urgent action as early visual loss does not necessarily indicate a poor prognosis. The depth and direction of penetration and size of wooden fragments is difficult to assess clinically and radiologically. Immediate and delayed neurological complications should always be anticipated. Removal of all fragments of wood is of paramount importance in restoring visual acuity. Prolonged visual loss with symptoms and signs of retained foreign body demands vigorous management.
两名儿童因眼眶被木头穿透伤导致突然失明后恢复了视力。无光感需要紧急处理，因为早期视力丧失不一定预示预后不良。临床上和放射学上很难评估木头碎片的穿透深度、方向和大小。应始终预见到即时和延迟的神经并发症。取出所有木头碎片对恢复视力至关重要。伴有异物存留症状和体征的长期视力丧失需要积极处理。
