Congenital nasolacrimal obstruction is a common disorder in infants that results in persistent tearing and may lead to infections, such as dacryocystitis, orbital cellulitis, and bacterial conjunctivitis. The true incidence of this disorder in healthy newborns remains controversial. The most frequently quoted number of 6% comes from a study of 200 consecutive live births in the 1940s in which nasolacrimal patency was assessed by the presence or absence of discharge on compression of the lacrimal sac. Estimates from other studies, which often use different criteria for diagnosis, vary considerably from 1.2% to 30%. The incidence of the disorder is higher in children who have craniofacial disorders and Down's syndrome. This article reviews the causes and treatment of congenital nasolacrimal obstruction.

Objective: This study aims to determine the outcomes of probing and external dacryocystorhinostomy (exDCR) for congenital nasolacrimal duct obstruction (cNLDO) and the factors influencing the success rates in pediatric cNLDO.
Design: A retrospective sample collection was conducted at the oculoplastic referral center over 10 years (January 2012 to December 2022) for cNLDO patients who had undergone probing or exDCR.
Methodology: Data were retrospectively reviewed for patients aged ≤18 years who underwent probing or exDCR.

Purpose: To evaluate the role of Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, Serratia marcescens, and Moraxella catarrhalis in the nasal and ocular surface flora, along with their metabolic activities in children with unilateral congenital nasolacrimal duct obstruction (CNLDO).
Methods: Swabs were taken from the bilateral inferior meatus and ocular surface of 26 children with unilateral CNLDO before probing. Nasal and ocular surface swabs from non-operated eyes of children who underwent unilateral blepharoptosis or strabismus surgery formed the control group.

Article Synopsis
- Congenital dacryocystoceles are uncommon birth defects linked to blocked tear ducts, presenting symptoms like excessive tearing and swelling around the eye.
- A new minimally invasive endoscopic procedure was tested on 19 infants and young children, focusing on resecting the affected tissue without further manipulating the lacrimal duct, aiming to reduce complications.
- The treatment was effective, with a recurrence in only two older patients, while the rest showed no issues post-surgery, suggesting this method is beneficial but may be less successful in older children with previous infections.
The Impact of Systemic Inflammation on Recurrence in Patients with Congenital Nasolacrimal Duct Obstruction.

/ Congenital nasolacrimal duct obstruction (CNLDO) is commonly treated by probing, but recurrence remains a clinical issue. This study investigates the potential role of inflammatory biomarkers, such as the neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and platelet-to-lymphocyte ratio (PLR), in predicting recurrence after probing in children with CNLDO. This retrospective cohort study included 172 patients who underwent initial probing for unilateral CNLDO.

Background: Congenital nasolacrimal duct obstructions that persist after 9 months of age often require surgical intervention through probing and stenting of the tear duct. These procedures typically occur under general anesthesia in an operating room setting. We propose a novel approach using intravenous sedation outside the operating room.
