AIM:To determine the 15-year outcomes of laser dacryoplasty(LDP)in patients with lacrimal duct obstruction;and to evaluate LDP combined with intubation using a new silicone tube to treat complicated cases.METHODS:Patients with lacrimal duct obstruction and treated with LDP between April 2000 and April 2005 were investigated retrospectively.Totally 116 eyes with completed 15-year follow-up records were included in this study.For complicated cases(52 eyes of 52 patients),both LDP and intubation using a self-made silicon tube were performed.For patients with uncomplicated obstruction(64 eyes of 61 patients),only LDP was performed.Outcomes were assessed based on results of lacrimal irrigation and degree of symptoms during follow-up.RESULTS:At the follow-up time of 15y,81 eyes achieved full success(69.8%);21 eyes got improved(18.1%);and 14 eyes were considered failure(12.1%).The success rate was 71.2%(37/52 eyes)for complicated cases;and 68.8%(44/64 eyes)for uncomplicated cases.No statistically significant difference between two groups was observed(P=0.961).No postoperative complication was observed.CONCLUSION:LDP is a well-tolerated,simple,and effective procedure with satisfactory long-term outcomes in selected patients,which make it a good alternative to conventional dacryocystorhinostomy.In addition,intubation with the self-made mono-canalicular silicone tube facilitates the management of complicated cases with few complications. 展开更多

AIM:To evaluate the long-term sucess rate of laserassisted dacryocystorhinostomy (L-DCR) in patients with nasolacrimal duct obstruction (NDO).METHODS:Forty-one eyes of forty patients aged between 21-85y (mean 56.7y) who underwent L-DCR for the treatment of NDO were included in this retrospective,non-randomized study. The follow-up time was 72mo.Functional sucess was defined as the disappearance of epiphora under normal conditions and the presence of a patent ostium on lacrimal irrigation. Anatomical success was defined as a patent lacrimal passage on syringing besides continuing epiphora. Surgical failure was defined as persistent epiphora and closed ostium.RESULTS:Twenty-seven of 40 patients (67.5%) were female and 13 of 40 patients (32.5%) were male. The NDO was right-sided in 17 (42.5%) patients and left-sided in 22(55%) patients whereas 1 (2.5%) patient had undergone bilateral surgery. In 11 (27.5%) patients there were additional nasal abnormalities requiring simultaneous surgical approach. The average time for L-DCR was 26.50±4.9min(16-39min) and the average total amount of laser energy used was 287±27.9 J (239-367 J). At the 5y follow-up, anatomical sucess rate was 75.0%(30 patients) and functional success rate was 65.0%(26 patients), whereas surgical failure was seen in 25%(10 patients). Revision of surgery was performed in 10 cases (25.0%); failure of revision surgery was seen in 2 cases(5.0%).CONCLUSION: Transcanalicular L-DCR is a reliable and fast procedure in the treatment of NDO. It can be alternative to external DCR which is accepted as the gold standard currently. The functional and anatomical success rate is higher in the first months and years, but still satisfactory at fifth year. 展开更多

Objective: To study the effect of mitomycin (MMC) combined with Nd-YAG laser on cell proliferation and invasion as well as MEK/ERK signaling pathway in obstructive lacrimal duct model. Methods: New Zealand rabbits were selected as experimental animals and divided into model group, laser group and MMC + laser group;obstructive lacrimal duct model was established, then laser group were given Nd-YAG laser intervention, and MMC + laser group were given Nd-YAG laser combined with mitomycin intervention. 2 months after intervention, the expression of proliferation molecules, invasion molecules and MEK-ERK signaling molecules in lacrimal duct tissue were measured. Results: TGF-β, CTGF, PCNA, Ki-67, Col-I, Col-III, MEK, ERK1/2, MMP2 and MMP9 protein levels in lacrimal duct tissue of laser group were significantly higher than those of model group while TSG-6, Cthrc1 and TIMP1 protein levels were significantly lower than those of model group;TGF-β, CTGF, PCNA, Ki-67, Col-I, Col-III, MEK, ERK1/2, MMP2 and MMP9 protein levels in lacrimal duct tissue of MMC + laser group were significantly lower than those of laser group while TSG-6, Cthrc1 and TIMP1 protein levels were significantly higher than those of laser group. Conclusion:Mitomycin can inhibit cell proliferation and invasion as well as MEK/ERK signaling pathway activation in obstructive lacrimal duct model after Nd-YAG laser treatment. 展开更多

AIM: To compare the success rate of monocanalicular versus pushed monocanalicular silicone intubation(PMCI)of the nasolacrimal duct for congenital nasolacrimal duct obstruction(CNLDO).METHODS: In a prospective randomized clinical trial 53 eyes of 49 patients with CNLDO underwent either monocanalicular silicone intubation(MCI)(n =28 eyes) or PMCI(n =25 eyes). All procedures were performed by 1oculoplastic surgeon. Treatment success was defined as the complete resolution of epiphora at 3mo after tube removal.RESULTS: The surgical outcome was assessed in 20 eyes with MCI and 20 eyes with PMCI. The mean age of treatment was 26.25 ±10.08mo(range, 13-49mo) for MCI and 26.85±12.25mo(range, 16-68mo) for PMCI. Treatment success was achieved in 18 of 20 eyes(90.0%) in the MCI group compared with 10 of 20 eyes(50%) in the PMCI group(P =0.01). In the PMCI group, the tube loss(30%)was greater than the MCI group(5%), however the differences between the 2 groups proved to be not significant(P =0.91).CONCLUSION: Our results indicate that MCI has higher success rate in CNLDO treatment compared with PMCI in this small series of patients. 展开更多

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 nasolacrimal 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 period 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). Alter 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. 展开更多

BACKGROUND Nasolacrimal duct obstruction leading to epiphora is a common ophthalmologic complaint,and it may derive from amyloidosis in rare cases.There are a few reports about localized amyloidosis,and amyloidosis with involvement and obstruction of the nasolacrimal duct is exceedingly rare.CASE SUMMARY A 54-year-old male presented with a 2-year history of a lump overlying the left lacrimal sac that had grown rapidly for nearly half a year.Physical examination touched a firm lump in the left lacrimal sac.Nasal endoscopy discovered lesions in appearance of sediments with easy bleeding at the entry of the nasolacrimal duct of the left inferior nasal meatus.Computerized tomography scan revealed speckle high density in the left lacrimal sac and the dilated nasolacrimal duct.During an endoscopic exploration and excision,a large number of dacryoliths were exposed.Pathology indicated amorphous pink material and multinucleated giant cell reaction in the fibrous tissue.CONCLUSION This case showed amyloidosis in localized form mimicking dacryolith with nasolacrimal duct obstruction.In clinical practice,we should be aware of the possibility of localized amyloidosis in the nasolacrimal excretory system. 展开更多
