Acquired Nasolacrimal Duct Obstruction
Otolaryngologic Clinics of North America, 2006Acquired nasolacrimal duct obstruction is a common problem. Although tearing is the usual complaint, the clinical presentation can range from a patient having no symptoms to one with a life-threatening infection. Despite many studies providing useful clues, the exact pathophysiology of the obstructive process is incompletely understood.

Mascara-induced nasolacrimal duct obstruction
BMJ Case Reports, 2021A 35-year-old woman underwent left external dacryocystorhinostomy (DCR) following a recent bout of left acute dacryocystitis. She had a right DCR 14 years earlier. Her relatively young age of presentation prompted suspicion of secondary nasolacrimal duct obstruction and, although the left lacrimal sac appeared macroscopically normal peroperatively, a ...

THC:YAG Nasolacrimal Duct Recanalization
Ophthalmic Surgery, Lasers and Imaging Retina, 1993ABSTRACT In an early exploration of a new technique for creating a patent nasolacrimal duct system, a chromium-sensitized and thulium- and holmium-doped YAG laser was used to canalize the nasolacrimal duct of a fresh-frozen bisected human cadaver head. The laser-long-pulsed (300 milliseconds), compact, self-contained, and solid-state-operates

Pediatric nasolacrimal duct obstruction
Current Opinion in Ophthalmology, 2013Review the current management for pediatric nasolacrimal duct obstruction and congenital dacryocele.Early probing in the office, and probing beyond 1 year of age in a facility with general anesthesia are equally effective. Congenital nasolacrimal duct obstruction is associated with anisometropic amblyopia. Infants with unilateral dacryocele are at risk

An Isolated Nasolacrimal Duct Osteoma
Journal of Craniofacial Surgery, 2013Osteomas of the nose and paranasal sinus are common benign tumors that can extend to surrounding structures and result in orbital or intracranial involvement. Presenting symptoms include facial pain, headache, cerebral symptoms, ocular symptoms, and so on, depending on the location and size of the tumor. They commonly occur within the frontal, ethmoid,

Techniques in Vascular and Interventional Radiology, 1999
The lacrimal drainage system extends from the puncta to the lower end of the nasolacrimal duct in the wall of the inferior nasal meatus. Epiphora usually results from obstruction of the lacrimal drainage system. Although there are many causes of obstruction of the lacrimal drainage system, most cases are due to idiopathic inflammation and scarring ...

Nasolacrimal Duct Anomaly in Calves
Journal of the American Veterinary Medical Association, 1975SUMMARY Supernumerary openings of the nasolacrimal drainage apparatus were found in 13 Brown Swiss calves. The cause of the anomaly was not determined but was assumed to be similar to that in man.

Congenital nasolacrimal duct obstruction occurs in approximately 5 % of newborns. The blockage occurs most commonly at the valve of Hasner located at the distal end of the nasolacrimal duct. The rate of spontaneous resolution is estimated to be at 90 % within the first year of life.

Nasolacrimal Duct Probing in Infants
Ophthalmology, 1979Use of a fiberoptic endoscope to visualize the vault of the inferior turbinate during lacrimal duct probing and irrigation revealed a high incidence of false passages. This was confirmed on dacryocystofluoroscopy. The creation of false passages as documented by us can help explain clinical probing failure in apparently successful probings in which ...

OCCLUDED NASOLACRIMAL DUCTS IN INFANTS
Archives of Ophthalmology, 1950To the Editor. —In a recent article by Dr. Martin P. Koke, entitled "Treatment of Occluded Nasolacrimal Ducts in Infants," published in the April 1950 issue of theArchives, page 750, the author reports his experience in the treatment of congenital impatency of the nasolacrimal duct and discusses an article on the same subject published by us ...
