泪道探通联合粘弹剂留置在泪道阻塞和泪小管断裂伤的应用研究

目的：探讨泪道探通并管结合透明质酸钠注入留置.对泪道阻塞及泪小管断裂吻合术后预防狭窄的治疗效果。方法：对47例54眼泪道阻塞及泪小管断裂吻合术后患者行泪道探通术并注入透明质酸钠治疗，观察泪道引流泪液功能的恢复情况。结果：随诊12～23个月，41眼(79.7％)泪道冲洗通畅，9眼(14.9％)溢泪症状减轻，4眼(5.4％)冲洗不通。结论：行泪道探通并留置管结合透明质酸钠注入是治疗泪道阻塞及泪小管断裂吻合术后预防狭窄的有效方法。

Clinical study on lacrimal passage probing with hyaluronic acid injecting into lacrimal passages in patients with obstruction of lacrimal ducts and canalicular laceration

Objective: To study the therapeutic efficacy of lacrimal passage probing with hyaluronic acid injecting into lacrimal passage ,used in preventing the lacrimal passage straitness in patients with obstruction of lacrimal ducts and canalicular laceration. Method: Probing of lacrimal passage with hyaluronic acid injecting into lacrimal passages had been used in treating 47 patients (54 eyes) with obstruction of lacrimal ducts and post-surgery of lacrinmal canaliculi anastomosis, then to observe lacrimal passages' drainage function. Result: Due to the follow-up 12 to 23 months after treatment, we found that 41 eyes were drained well , symptom of epiphora were relieved in 9 eyes and 4 eyes were blocked up. Conclusion: Probing of lacrimal passage with hyaluronic acid injecting into lacrimal passages is an effective method in preventing the lacrimal passage straitness in patients with obstruction of lacrimal ducts and lacrinmal canaliculi anastomosis.
