Introduction:
The congenital nasolacrimal duct obstruction is a common pathology, with low morbidity, but not exempt of complications without the correct diagnosis and management.
Methods:
Retrospective study from 2005 to 2015 in patients who were submitted to a probing procedure. We identified age at procedure, gender, laterality and presence or absence of success with the procedure.
Results:
One hundred thirty-seven eyes were analyzed. The median age was 17 months and the total success rate was 85.4%.
Conclusion:
In congenital nasolacrimal duct obstruction there is a high rate of spontaneous resolution with the proper initial conservative management and, in patients older than 12 months, probing has a high rate of success.

Thomson's e/m Experiment
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The magnetic...
Renal Tubule and Collecting Duct
Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
