To determine the long-term outcome in patients with a lesion of a single lacrimal canaliculus without surgical correction.
Prospective.
In the period August 1995-August 1999 16 patients were seen with a monocanalicular trauma. No attempt was made to reconstruct the canaliculus; only the superficial layers were closed (skin and M. orbicularis oculi). At follow-up the patients were asked about epiphora (score of Munk) and the test of Anel and the fluorescein dye disappearance test were carried out.
At follow-up a mean of 13.7 months (range: 3-33) after the trauma the injured canaliculus was totally blocked in all patients. In spite of this, none of the patients experienced epiphora either indoors or outdoors. Tear drainage of the ipsilateral unharmed canaliculus was functioning normally in such a way that epiphora was prevented.
In patients with a monocanalicular lesion repair of only the superficial layers of the eyelid without reanastomosis of the torn ends of the canaliculus is sufficient to maintain normal tear drainage. This procedure is safe and simple.
确定未接受手术矫正的单泪小管损伤患者的长期预后。
前瞻性研究。
在1995年8月至1999年8月期间，有16例患者出现单泪小管外伤。未尝试重建泪小管；仅封闭表层（皮肤和眼轮匝肌）。随访时询问患者溢泪情况（蒙克评分），并进行阿内尔试验和荧光素染料消失试验。
外伤后平均随访13.7个月（范围：3 - 33个月），所有患者受伤的泪小管均完全阻塞。尽管如此，所有患者在室内或室外均未出现溢泪。同侧未受伤泪小管的泪液引流功能正常，从而防止了溢泪。
对于单泪小管损伤的患者，仅修复眼睑表层而不重新吻合泪小管断端足以维持正常的泪液引流。该手术安全且简单。
