We report the results of office nasolacrimal duct probing under topical anesthesia in 2369 eyes with symptomatic nasolacrimal duct obstruction. The overall success rate for cure by initial probing was 92%. In patients less than 9 months old, a 94% cure rate was achieved with one probing; in patients 9 months and older, the rate decreased to 84%. The decrease in success rate after 9 months was statistically significant (P less than .00001 by chi-square analysis). A majority of 180 parents of these patients surveyed said they were happy with the office procedure and preferred having the probing performed to resolve symptoms, even though they realized that the symptoms most probably would resolve by 1 year of age without it. We conclude that office probing for congenital nasolacrimal duct obstruction is a safe and effective method for treatment of symptomatic nasolacrimal duct obstruction, allowing the cost and risk of general anesthesia as well as the cost and inconvenience of prolonged medical management to be avoided.
我们报告了2369例有症状性鼻泪管阻塞的眼睛在局部麻醉下行门诊鼻泪管探通术的结果。初次探通术的总体治愈率为92%。年龄小于9个月的患者，一次探通术的治愈率为94%；9个月及以上的患者，治愈率降至84%。9个月后成功率的下降具有统计学意义（经卡方分析，P<0.00001）。在接受调查的这些患者的180位家长中，大多数表示他们对门诊手术感到满意，并且更倾向于通过探通术来缓解症状，尽管他们意识到即使不进行手术，这些症状很可能在1岁时也会自行缓解。我们得出结论，门诊探通术治疗先天性鼻泪管阻塞是一种安全有效的方法，可避免全身麻醉的费用和风险以及长期医疗管理的费用和不便。
