Article Abstract
Background And Objectives: The treatment of congenital nasolacrimal duct (NLD) obstruction continues to be a subject of controversy. Some authors advocate early probing and irrigation in an office setting, whereas others recommend that the procedure be performed under general anesthesia when the child is at least 1 year old. The focus of this study was to compare the results of probing and irrigation of congenital NLD obstruction among children younger than 1 year of age, those 1 to 2 years of age, and those older than 2 years.
Patients And Methods: The author reviewed the records of 120 patients, ranging in age from 3 weeks to 30 years, with 153 cases of NLD obstruction. Eighty-five patients (110 cases of NLD obstruction) underwent probing and irrigation.
Results: Complications of NLD obstruction occurred in 12 patients; 75% of these patients were younger than 1 year of age. In group 1 (patient age < 1 year) there were 37 probings with 1 failure (3%). Group 2 (patient age = 1-2 years) had 43 probings and 5 failures (12%). In group 3 (patient age > 2 years), 30 NLDs were probed with 2 failures (7%). However, these differences were not significant (P = .13 between groups 1 and 2; P = .42 between groups 1 and 3).
Conclusion: In this study, the postponement of probing and irrigation for congenital NLD obstruction beyond the age of 1 year did not result in an increased rate of failures or complications.

Article Synopsis
- A clinical study assessed the effectiveness of 3D CT-DCG-assisted and endoscopically guided coronary catheter balloon dacryoplasty (CC-BDCP) for adults with focal stenosis of the nasolacrimal duct (NLD), involving 25 patients in total.
- Out of the 25 patients, 21 underwent the CC-BDCP procedure, achieving a significant improvement in epiphora intensity and functional outcomes postoperatively, with overall scores significantly decreased from preoperative values.
- The overall success rate of the procedure was 77%, with 90% success in patients deemed "easy" to treat and 64% in those classified as "difficult," indicating varying outcomes based on procedural difficulty.

Purpose: To evaluate how risk factors impact success rates of initial probing and nasolacrimal duct (NLD) tube intubation in children over 18 months of age with congenital nasolacrimal duct obstruction (CNLDO).
Methods: This cohort study included 98 CNLDO patients aged 18 months to 10 years who underwent NLD probing with stent insertion. We employed the multivariate frailty model as our final model to conceptually elaborate on our correlated eye data, with the primary outcome measure evaluating the success rates of probing and tube intubation.

Purpose: To report a rare case of a pediatric dacryolith masquerading as congenital nasolacrimal duct obstruction (CNLDO).
Observations: A two-year-old male child presented with history of intermittent epiphora and discharge since the age of six months. Clinical evaluation demonstrated raised tear meniscus height and delayed fluorescein dye disappearance test in the right eye.
Background Pediatric obstructive sleep apnea (POSA) is a common sleep disorder that can cause major health problems if untreated. Parental knowledge and awareness are critical for early detection and management of POSA in children. This study sought to measure parents' and caregivers' knowledge and awareness of pediatric POSA in Jazan, Saudi Arabia, as well as to uncover sociodemographic correlates of knowledge levels.

Purpose: This prospective observational study aimed to explore the diversity in lacrimal pathway morphology among patients with congenital nasolacrimal duct obstruction (CNLDO) by examining dacryocystography (DCG) images.
Patients And Methods: The study included 64 patients who underwent DCG before undergoing general anesthesia probing for unilateral CNLDO. Several parameters were measured from the lateral view of the DCG images: (1) the lacrimal sac (LS) and the nasolacrimal duct (NLD) angle, (2) the angle formed by the superior orbital rim (SOR), LS, and the NLD, (3) LS length, and (4) bony NLD length.
