Introduction: Lacrimal drainage system disorders are among the most common ocular disorders faced by physicians. The prevalence of congenital nasolacrimal duct obstruction (CNLDO) is different in various studies, and the role of such factors as maternal and neonatal demographic characteristics have not been completely investigated in CNLDO. The present study aimed to assess the prevalence of CNLDO and its related factors in newborns in Sabzevar. Methods: This cross-sectional study was conducted on 541 newborns in Shahidan Mobini hospital, Sabzevar, Iran from January to February 2015 after obtaining informed consent from their parents. Data were collected by interviewing mothers, filling out checklists, and physical examination of the newborns. Data analysis was carried out in Stata software using a logistic regression test at a 95% confidence interval. Results: The prevalence of CNLDO was 22.6%. Purulent ocular discharge was the most common symptom (16.82%). There was a significant relationship between the neonate’s head circumference and the incidence of CNLDO (P= 0.01); nonetheless, CNLDO in the newborns showed no significant association with weight, height, and Apgar score (P>0.05). Conclusion: Considering the significant prevalence of CNLDO in preterm and term neonates, as well as its variable prevalence rates reported in different studies and the absence of overlapping of various risk factors of such disorder, it is recommended to carry out more thorough studies from birth to 1 year of age.

Background: Primary acquired nasolacrimal duct obstruction (PANDO) is a common entity with associated different types of intranasal abnormalities. The pathogenesis of PANDO is unknown. The objective of the study was to describe the intranasal findings in cases of PANDO and find out any association of these findings to the disease. Methods: A comparative cross-sectional study was designed consisting of 50 cases of unilateral PANDO with epiphora and 50 normal volunteers with no history of epiphora. Nasal Evaluation was done with anterior rhinoscopy and nasal endoscopy. Data was tabulated and analyzed using SPSS version 21. Results: The mean age in the unilateral PANDO group was 33.6 years and 34.5 years in the normal volunteer’s group (P-0.84). Left sided dominance of PANDO was observed in 64% (32/50) cases. The odds of having Nasolacrimal duct (NLD) obstruction was1.6 times more among individuals having septal deviation versus no deviation (95% CI, 0.907–2.78). The laterality of septal deviation was corresponding to the side of NLD obstruction in 91% (31/34) cases. High located DNS was more common in the PANDO group which was significant (P-value 0.012). Turbinate hypertrophy, the presence of septal spur or rhinitis had no significant association with NLD obstruction. Conclusions: Deviated nasal septum (DNS), turbinate hypertrophy, septal spur and rhinitis were the associated intranasal findings in cases of unilateral PANDO. A significant association exists between DNS and PANDO, although a cause and effect relation require further probing.

Background: Congenital nasolacrimal duct obstruction (CNLDO) is one of the commonest problems encountered in daily ophthalmology practice. Though probing and syringing is the mainstay of management of CNLDO, there is no clear guideline about the optimal time to perform.Aims and Objective: To evaluate the efficacy of probing and syringing in cases of congenital nasolacrimal duct obstruction in various age groups.Materials and Methods: In this prospective, hospital based, interventional, cross-sectional study done over a period of 2 years (July 2015- June 2017), children of various age ranging from 10 days to 8 years who underwent probing and syringing under general anesthesia for CNLDO refractory to conservative measures were included. Results: Children of as young as 10 days to as older as 8 years underwent probing and syringing with male to female ratio of 1.2:1. Overall success was 80.6% (58/72) which was statistically significant when analyzed with age (P = 0.006). Majority of cases with successful outcome were below 24 months of age (90.62%). There was predominance of membranous obstruction (128/194) over bony obstruction (66/194). Conclusions: Nasolacrimal duct probing under GA is a safe and viable option as a primary treatment modality for CNLDO. Though the success of probing is high in the younger children, it’s worthwhile to consider the same in older children at least up to 5 years of age before going for more invasive procedure like DCR surgery since more than 2 third of probing has successful outcome up to that age.Asian Journal of Medical Sciences Vol.9(6) 2018 57-61

Purpose: Sialoendoscope was used as a dacryoendoscope, high- definition images of the lacrimal drainage system (LDS) were captured and its performance in congenital nasolacrimal duct obstruction (CNLDO) is reported. Methods: Nasal endoscopy was done as the first in all the cases using a 0°, 2.7 mm nasal endoscope (Karl Stroz Tutlingan Germany). This was followed by Dacryoendoscopy (DEN) of the lacrimal drainage system from puncta till the valve of Hasner. DEN was performed under general anaesthesia in 26 children (including 17 primary and 9 failed probing cases). All cases were examined using 0.8 mm sialoendoscope (Karl Storz, Tuttlingen, Germany) with fibreoptic light transmission with a side port for irrigation. Results: We were able to obtain high-definition images of canaliculi, lacrimal sac, sac duct junction, proximal, mid and distal segments of nasolacrimal duct in all the children with CNLDO. In 17 primary cases 16 had distal membranous obstruction and I case had proximal canalicular obstruction. In nine children with history of failed probing, five had membranous obstruction, two had dacryoliths, two had NLD malformation at different levels. An overall success rate of 88.4% was achieved. Conclusion: Sialoendoscope can be used as high-definition dacryoendoscope for diagnostic and therapeutic use in CNLDO. Useful information can be obtained on dacryoendoscopy in complex CNLDO cases.

Summary The study aimed to identify the type of refraction in children with unilateral and bilateral congenital nasolacrimal duct obstruction (CNLDO) who underwent nasolacrimal duct probing. One hundred and twelve children aged 1.8 to 13 years, diagnosed with CNLDO, were included in a retrospective study. All the patients had their visual acuity examined, and their refractive status was evaluated. The refractive errors of both eyes were noted, followed by an appropriate management plan. Of the 112 children, 79 (70.5%) had a unilateral obstruction, and 33 (29.5%) had bilateral obstruction. Nine children (11.4%) in the former group and six children (18.2%) in the latter group were with visual acuity <0.8. The most frequent refractive error among the studied children was hyperopia. No statistically significant difference (p>0.05) between refraction of the two eyes in the evaluated children were found. Amblyopia risk factors were identified in 9 of the patients (8.0%). CNLDO did not adversely affect the refractive status. However, amblyogenic risk factors were found more often in our patients, as compared to general populations. Therefore, a detailed evaluation should be performed to find out these risk factors.
