Congenital lacrimal sac diverticulum

Journal of American Association for Pediatric Ophthalmology and Strabismus, 2020
We report the case of a 6-month-old boy with recurrent episodes of acute dacryocystitis from age 3 months to 1 year of age. The cause was determined to be congenital nasolacrimal sac diverticulum, a rare and commonly asymptomatic entity. An isolated diverticulectomy without dacryocystorhinostomy was performed because of lacrimal drainage system patency.

Novel Evidence Concerning Lacrimal Sac Movement Using Ultra-High-Frequency Ultrasound Examinations of Lacrimal Drainage Systems

Ophthalmic Plastic and Reconstructive Surgery, 2020
Purpose: Current hypothesis regarding the mechanism of active tear drainage is based on studies performed ex vivo or under nonphysiological conditions. Novel ultra-high-frequency ultrasound has the advantage of generating images with superior resolution,
