ABSTRACT
@#AIM: To explore the application effect of mitomycin C in lacrimal duct obstruction during anterograde lacrimal drainage tube implantation. <p>METHODS:Totally 78 cases of lacrimal duct obstruction(82 eyes)were randomly divided into the observation group(39 cases, 42 eyes)and the control group(39 cases, 40 eyes), and the control group was treated with lacrimal drainage tube implantation. The observation group was based on this combined mitomycin C treatment and compared the effect of two groups. <p>RESULTS: The total effective rate of the observation group was 81%, which was significantly higher than that of the control group(62%), and the difference between the two groups was statistically significant(<i>P</i><0.05). The eye surface change score(26.25±1.67)and tear SP content(256.32±10.07pg/mL)were lower than that of the control group after treatment. The tear film rupture time(8.85±0.89s)was shorter than that of the control group(9.58±0.92s), and the two groups were statistically significant(<i>P</i><0.05). <p>CONCLUSION: Mitomycin C can improve the efficacy of anterograde lacrimal drainage tube implantation for the treatment of lacrimal duct obstruction and improve prognosis.
ABSTRACT
·AlM: To explore the treatment effect of initial lacrimal passage irrigation and probing in neonatal dacryocystitis. · METHODS: ln this retrospective case series study, 224 outpatients ( 256 eyes ) with neonatal dacryocystitis were selected from January 2012 to December 2012 in our hospital.The patients were divided into 5 groups ( 1 ~3mo, 4~60mo, 7 ~9mo, 10 ~12mo and >12mo).lnitial lacrimal passage irrigation and probing were operated, the therapeutic effect of different groups were compared. ·RESULTS:ln this study, 256 eyes of 224 cases, 242 eyes (94.5%) were cured and 14 eyes ( 5.5%) were failed. Bony nasolacrimal duct obstruction happened more obviously in children aged more than 10mo with lower cure rate.More probing was required with the children aged (Spearman rank correlation analysis, γs=0.746, P · CONCLUSlON: The treatment of primary lacrimal passage irrigation and probing in neonatal daryocystitisis effective and safe, the optimal timing of treatment is 1 ~9mo.With the growth of age, the cure rate is decreased.
ABSTRACT
The diagnosis and treatment of the lacrimal passage obstruction with lacrimal endoscope was investigated and its subsidiary surgical procedures were evaluated. Ninety-three patients (109 eyes) with lacrimal passage obstruction, including presaccal canalicular obstruction (PSCO) and na-solacrimal duct obstruction (NLDO), were examined under a lacrimal endoscope, and the obstruc-tions were treated with laser or micro-drill. All patients were followed up after the operation for 3-6 months. The difference between the laser and the micro-drill treatment was observed. During the pe-riod of follow-up, the curative rate was 82.57%. The healing rate in PSCO group and NLDO was 80.36% and 84.91% respectively (P>0.05). After treatment with the laser, the healing rate was 93.33% in the PSCO group and 66.67% in the NLDO group respectively (P<0.05). After treatment with the micro-drill, the healing rate in PSCO and NLDO groups was 65.39% and 94.28% respec-tively (P<0.01). The lacrimal passage obstruction can be observed and treated directly through the lacrimal endoscope. Choosing different surgical procedures in operation according to the locations of the obstruction is helpful to improve the effectiveness.
ABSTRACT
A high-frequency electroeission was performed on 16 cases with lacrimal canaliculus cicatricial obstruction with ages ranging from 19 to 54 years old, and the instrument was made by the authors. The results of 4—22-month follow-up showed that the cure rate was 93.8%. This method is a nonsurgical therapy with less trauma, and it is not necessary to make a skin incision. The cure rate is not affected by the degree of the defect of lacrimal canaliculus, and it is suitable for treatment of canaliculus obstructions caused by various etiologic factors. After electrueission, for supporting purpose a minimegaphone-shaped tube is inserted into the lacrimal passage between the canalieular ampulla and the nasal cavity. In such a management, the tube is fixed relatively good, no tube is left and fixed out of the lacrimal passage at the outer eye, leading to no eosmetie defect, and the laerimal drainage problem is solved after the therapy before the tube is taken away. The method is simple and its therapeutic results are satisfactory.
