Insights
Cesarean section during a first birth and a family history of the condition are significant risk factors for congenital nasolacrimal duct obstruction in infants. This finding aids in understanding the condition
Area of Science:
- Ophthalmology
- Neonatal Care
- Genetics
Background:
- Congenital nasolacrimal duct obstruction (CNLDO) is a common condition in infants.
- Understanding its risk factors is crucial for early diagnosis and management.
Purpose of the Study:
- To investigate the association between birth type and the incidence of CNLDO.
- To identify potential risk factors contributing to the development of CNLDO.
Main Methods:
- A cohort of 665 infants with suspected CNLDO was analyzed.
- Data collected included delivery type, birth order, and family history.
- Infants were compared based on the presence or absence of CNLDO.
Main Results:
- CNLDO was diagnosed in 34.1% of the infants.
- Infants with CNLDO had a significantly higher rate of cesarean section, especially in first births (58.7% vs. 20.7%).
- A positive family history was also more prevalent in infants with CNLDO.
Conclusions:
- Cesarean section in first-time mothers and a family history of CNLDO are significant risk factors.
- These factors may play a role in the etiopathogenesis of CNLDO.
Purpose:
The aim of this study was to research the relationship between types of birth and congenital nasolacrimal duct obstruction.
Method:
The study enrolled 665 infantile patients with prediagnosis of congenital nasolacrimal duct obstruction due to associated ophthalmic symptoms. Age, gender, family history, delivery type, and patient medical records were investigated. Patients were grouped and compared according to their birth type and whether it was the first birth.
Results:
The number of the infants with and without congenital nasolacrimal duct obstruction was 227 (34.1%) and 438 (65.9%), respectively. Comparison of the congenital nasolacrimal duct obstruction and non-congenital nasolacrimal duct obstruction groups according to the first births showed that ratio of cesarean section was significantly higher in the congenital nasolacrimal duct obstruction group than the non- congenital nasolacrimal duct obstruction group (58.7% and 20.7%, respectively). Number with positive family history also was significantly higher in the congenital nasolacrimal duct obstruction group.
Conclusion:
Cesarean section in first birth and positive family history of congenital nasolacrimal duct obstruction appear to be important risk factors in the etiopathogenesis of congenital nasolacrimal duct obstruction.
