目的：观察不同方法治疗获得性泪点狭窄或粘连的疗效，探寻获得性泪点狭窄或粘连比较理想的治疗方法。

方法：获得性泪点狭窄或粘连患者52例72眼，采用随机数字表法分为治疗组和对照组，治疗组27例36眼，采用改良式泪点切开联合硅胶管置入术； 对照组25例36眼，采用硅胶管置入术，随访12mo，观察两组疗效。

结果：治疗组总有效率为94%，对照组总有效率为78%，两组比较差异具有统计学意义(P<0.05)。治疗组脱管率为6%，对照组脱管率为8%，两组患者术后脱管率相近，差异无统计学意义(P>0.05)。两组患者均未发生泪点撕裂。

结论：改良泪点切开联合硅胶管置入术操作简单，损伤小，恢复快，有效率高，是治疗获得性泪点狭窄或粘连比较理想的手术方法。

METHODS: Totally 52 cases(72 eyes)suffered from acquired lacrimal point stenosis or adhesion, were divided into treatment group and control group by random number table, in which 27 cases(36 eyes)in treatment group were treated by modified tear incision combined with silicone tube implantation, 25 cases(36 eyes)in control group were treated by silicone tube implantation. All cases were followed up for 12mo.

RESULTS: The total effective rate of the treatment group was 94%. The total effective rate of the control group was 78%. The difference between two groups was statistically significant(P<0.05). Silicone tube shedded in two eyes in treatment group and three eyes in control group. The rate of silicone tube shedded in two was 6% and 8%, respectively. The difference between two groups was not statistically significant(P>0.05). None case had lacrimal point tear in two groups.

CONCLUSION: Modified tear point incision combined with silicone tube implantation is the better operative methods on acquired lacrimal point stenosis or adhesion. It is easily operating, less damage with quick recovery. And effective rate is high.
