During the procedure, the horizontal portion of the normal lower canaliculus was identified;the corresponding punctum was reconstructed via retrograde canaliculotomy and punctoplasty. Intubation was performed to prevent postoperative reocclusion. Patients were followed up for 12 to 24 mo. A total of 16 patients with unilateral upper and lower lacrimal punctal occlusion were included. Satisfactory outcomes were achieved: all 16 patients exhibited improvement of epiphora;31 rebuilt punctal openings and canaliculi achieved recanalization. Only one upper punctal opening could not be reconstructed because the corresponding canaliculus exhibited severe injury. No significant complications occurred as a result of the treatments. Retrograde canaliculotomy and punctoplasty appears to effective, safe, and minimally invasive for treatment of upper and lower punctal occlusion.展开更多
