目的 比较泪道激光成形后联合与不联合鼻泪管支架置入术治疗鼻泪管阻塞的临床效果.方法 76例(80眼)随机分为两组:A组,鼻泪管阻塞36例(38眼)行单纯泪道激光成形术;B组,40例(42眼)鼻泪管阻塞行泪道激光成形术后再置入鼻泪管支架.术后随访6个月,观察两组治疗效果,并进行比较分析.结果 A组显效率36.84％,有效率28.95％,无效率34.21％,总有效率为65.79％;B组显效率64.29％,有效率30.95％,无效率4.76％,总有效率为95.24％.两组间差异有统计学意义(x2=12.186,P =0.002).结论 泪道激光联合鼻泪管支架置入术治疗鼻泪管阻塞是一种较为有效的治疗方法.“,”Objective To compare the clinical efficacy after laser dacryocystoplasty combined with or without nasolacrimal duct stent placement in the treatment of nasolacrimal duct obstruction.Methods Total of 80 eyes of 76 cases were randomly divided into two groups:Group A,38 eyes of 36 patients treated with laser dacryocystoplasty;Group B,42 eyes of 40 patients treated with laser dacryocystoplasty combined with nasolacrimal duct stent intubation.The follow-up time was 6 months.Nasolacrimal duct stent was kept for 3 months.And the treatment efficacy of the two groups were compared and analyzed.Results The treatment efficacy was very significant in 14 eyes (36.84％) of Group A and the symptoms improved in 11 eyes (28.95％).The total effeciency rate was 65.79％.The treatment effect was very significant in 27 eyes (64.29％) of Group B and the symptoms improved in 13 eyes(30.95％),the total efficiency rate was 95.24％.After statistical analysis,there was significant difference between the two groups (x2 =12.186,P =0.002).Conclusion Laser dacryocystoplasty combined with nasolacrimal duct stent intubation in the treatment of nasolacrimal duct obstruction is more effective.
