High-resolution dacryoendoscopy for observation for pediatric lacrimal duct obstruction
نویسندگان
چکیده
Purpose The aim of this study was to describe high-resolution dacryoendoscopy findings for nasolacrimal duct obstruction (NLDO) in three representative pediatric cases with different etiologies. Observations In a case of congenital NLDO, a mucosal membranous obstruction was observed at the distal end of the nasolacrimal duct (NLD), and a slit-shaped opening of the NLD was observed after perforation. In a case of acquired NLDO secondary to an adenoviral infection, a membranous obstruction was observed at the proximal NLD. In a case of NLDO with chronic dacryocystitis in a patient with Down syndrome, diffuse fibrous obstruction was observed. Conclusion and importance High-resolution dacryoendoscopy enables a clearer visualization of pediatric lacrimal duct obstructions, leading to an improved understanding of their features.

The lacrimal system is comprised of the lacrimal glands for tear production and the lacrimal drainage system for draining tears away from the eyes. Congenital lacrimal system anomalies other than nasolacrimal duct obstruction are uncommon. Congenital lacrimal fistulae are a rare developmental anomaly, and when they occur, they are usually unilateral. Fistulae and diverticulae can originate from...

Observation is a simple and reliable tool with the clinician. The level of tears, position of puncta, lids and eyelashes should be noted. Obstruction of the tear drainage system can be acquired or congenital, it is important to rule out acquired causes of tearing such as corneal, lid or lash abnormalities. Lacrimal obstruction problems can be divided as related to upper (puncta to lacrimal sac)...
