目的：探讨泪道探通术联合妥布霉素地塞米松眼膏填充治疗对泪道阻塞患者眼表症状和生活质量的影响。

方法：选取2016-10/2018-01我院收治的泪道阻塞患者120例120眼，按照治疗方法分为对照组(n=60)和观察组(n=60)。对照组予以单纯泪道探通术治疗，观察组予以泪道探通术联合妥布霉素地塞米松眼膏填充治疗。比较两组患者临床疗效、治疗前后眼表疾病指数量表(OSDI)评分及血清超敏C反应蛋白(hs-CRP)、降钙素原(PCT)水平的变化。

结果：观察组临床疗效明显优于对照组(P<0.05)。治疗后1mo，观察组OSDI总分及眼部不适频率评分、眼部不适对日常生活的影响评分、不良环境眼部不适发生频率评分均较术前明显降低(P<0.05)。治疗后1mo，观察组血清hs-CRP、PCT水平均明显低于对照组(P<0.05)。

结论：泪道探通术联合妥布霉素地塞米松眼膏填充治疗泪道阻塞疗效显著，能够有效改善患者眼表症状和生活质量。

METHODS: A total of 120 patients(120 eyes)with lacrimal duct obstruction treated in the hospital from October 2016 to January 2018 were selected. They were randomly divided into control group(n=60)and observation group(n=60)according to the treatment methods. The control group was treated with simple lacrimal duct probing while the observation group was treated with lacrimal duct probing combined with illing with tobramycin and dexamethasone. The clinical efficacy, changes in ocular surface disease index(OSDI)score, levels of serum high-sensitivity C-reactive protein(hs-CRP)and procalcitonin(PCT)before and after treatment were compared between the two groups.

RESULTS: The clinical efficacy in observation group was significantly better than that in control group(P<0.05). The total score of OSDI, scores of the frequency of eye discomfort, the effect of eye discomfort on daily life and the frequency of eye discomfort caused by adverse environment in the observation group were significantly decreased after treatment(P<0.05). The levels of serum hs-CRP and PCT in the observation group were significantly lower than those in the control group after treatment(P<0.05).

CONCLUSION: Lacrimal duct probing combined with tobramycin and dexamethasone is markedly effective in the treatment of lacrimal duct obstruction. It can effectively relieve the ocular surface symptoms and improve quality of life of patients.
