Congenital nasolacrimal duct obstruction is a common disorder in infants, with up to 20% of all newborns suffering from epiphora during the first year of life. This paper reviews the current evidence regarding the incidence, natural history, and management of congenital nasolacrimal duct obstruction. It highlights the role of nasendoscopy in improving the understanding of the condition, which has resulted in better overall management. 相似文献

This paper presents 4 cases in which the punctum had been temporarily occluded with tissue adhesive, still showing toxic tissue reaction years later. Abscess, dacryocystitis, dacryocystitis with dacryolithiasis, dacryocellulitis and polyposis were found. In the light of these findings and the relevant literature-especially with regard to late injuries-it is not advisable to use tissue adhesive, at least not for the purpose of punctal occlusion. 相似文献

鼻泪管阻塞性疾病(NLDOD)是临床发病率较高的一种眼科常见病,是由于炎症或其他原因引起的鼻泪管部分或全部阻塞不通,主要表现为溢泪,继发泪囊炎可出现溢脓,继发泪囊囊肿导致泪囊扩大、内眦肿胀等,开通阻塞的鼻泪管则是治疗鼻泪管阻塞性疾病的关键,明确鼻泪道相关解剖参数在鼻泪管阻塞性疾病的诊断和治疗中显得极为重要。而泪道CT是泪道影像学检查常用方法之一,便于对鼻泪道相关解剖参数进行测量。本文综述近年来在鼻泪管阻塞性疾病中应用CT测量鼻泪道相关解剖参数的研究进展,主要包括鼻泪道及泪囊的经线、面积、体积、角度等,分析总结相关解剖参数与鼻泪管阻塞性疾病的相关性,以便更好地指导临床。 相似文献

Nasolacrimal tuberculosis is rare. The authors present a young Peruvian-born female with subacute onset of right eye epiphora, isolated right inferior turbinate enlargement, and ipsilateral cervical lymphadenopathy. Turbinate and neck mass incisional biopsies demonstrated histopathological findings consistent with tuberculosis. QuantiFERON-TB Gold-In-Tube testing was positive. Complete resolution of symptoms occurred after dacryocystorhinostomy and 9 months of standard 4-drug antituberculosis therapy. Tuberculosis of the nasolacrimal duct is highly unusual but should be considered in patients with tuberculosis risk factors who present with nasolacrimal obstruction from an inferior turbinate mass. 相似文献

PURPOSE: To ascertain the effect of certain parameters on nasolacrimal duct probing. METHODS: In a retrospective study of 142 infants and children who underwent nasolacrimal duct probing for congenital nasolacrimal duct obstruction, age at time of probing, gender, symptom severity, presence of mucous discharge, and history of probing were correlated with success of nasolacrimal probing. Success of probing was defined as complete resolution of signs and symptoms of nasolacrimal duct obstruction. Chi-square test was used to analyze covariance. RESULTS: Success of nasolacrimal duct probing was negatively correlated with increasing age: 92%, 89%, 80%, 71%, and 42% at age 12, 24, 36, 48, and 60 months, respectively (P = .001 at each interval). Increasing severity of epiphora was correlated with increased failure of nasolacrimal duct probing (P = .05). CONCLUSIONS: Although the success of nasolacrimal duct probing declines with age, probing in older children can remain the first line of treatment. Because increasing frequency of epiphora correlates with failure of nasolacrimal duct probing, children with daily epiphora should undergo early nasolacrimal duct probing. 相似文献

The long term results of probing for congenital nasolacrimal duct obstruction were reviewed using a parental questionnaire issued to both treated and age-matched control groups. On follow up 4-13 years after probing in childhood 30% of patients still had symptoms of epiphora or discharge. Surprisingly, a similar high symptom rate was found in the controls, such that there was no statistically significant difference in the rate of symptoms between the two groups. Probing had therefore apparently reduced the symptom rate to a level close to normal for the age group concerned. All studies on the incidence of congenital nasolacrimal duct obstruction must be interpreted with reference to the known high rate of spontaneous resolution as a clear trend has been demonstrated towards a lower incidence of symptoms the longer the follow up after probing. This finding would support a policy of delay before further intervention in patients with mild residual symptoms after a technically successful probing. 相似文献

PurposeTo characterize the outcomes of initial and repeated office-based probing as a primary treatment for congenital nasolacrimal duct obstruction (CNLDO) in children. MethodsThe medical records of patients who underwent nasolacrimal duct office-based probing for CNLDO between March 2004 and January 2008 were reviewed retrospectively. Nasolacrimal duct probing was performed on 244 eyes from 229 consecutive patients with CNLDO. Patients who were refractory to the first probing underwent a second probing 4 to 8 weeks later. ResultsBased on exclusion criteria, 244 eyes from 229 patients (117 males and 112 females), aged 6 to 71 months (mean, 12.4 ± 8.36) were included. The success rate of the initial probing was 80% (196 of 244) for all patients, 82% (111 of 136) in the 6 to 12 month age group, 79% (64 of 81) in the 13 to 18 months age group, and 78% (21 of 27) among individuals older than 19 months ( p = 0.868, Pearson chi-square test). The success rate of the second probing was 61% (25 of 41) for all patients, 74% (17 of 23) in the 6 to 12 months age group, 58% (7 of 12) in the 13 to 18 months age group, and 17% (1 of 6) among individuals older than 19 months ( p = 0.043, Fisher''s exact test). ConclusionsWhile the success rate of initial nasolacrimal duct probing is not affected by age, the rate of success rate with a second probing was significantly lower in patients older than 19 months. Based on the results, authors recommend further surgical interventions, such as silicone tube intubation or balloon dacryocystoplasty, instead of repeated office probing for patients older than 19 months, if an initial office probing has failed. 相似文献

AIM: To investigate nasolacrimal duct (NLD) volume in Korean patients and to examine the correlation between NLD volume and obstruction.
METHODS: Of patients who underwent orbital computed tomography from March 2013 to January 2016, patients diagnosed with NLD obstruction were classified into the patient group and patients without obstruction were classified into the control group. The NLD volume was measured using the Image J program, which showed the NLD in axial, coronal, and sagittal images on computed tomography.
RESULTS: The average value of men’s NLD volume, 265.33±90.57 mm3, was significantly larger than women’s, 211.87±68.61 mm3 (P=0.009). In the patient group, the NLD volume of the obstructed eyes, 242.49±82.93 mm3, and the non-obstructed eyes, 225.20±73.20 mm3, were significantly higher than the control group, 217.61±82.04 mm3 (P<0.001, P<0.001).
CONCLUSION: The NLD volume is larger in men than in women in Korean adults. If there is NLD obstruction in women, the NLD volume is larger and it is judged that inflammatory reaction caused a chronic change in the bone around the NLD and affect the measurement of NLD volume. 相似文献
