Congenital nasolacrimal duct obstruction (CNLDO) occurs in approximately 10 to 20% of all term newborns, and is the most common cause of persistent tearing and ocular discharge in children. CNLDO causes symptoms in up to 6% of children during the first year of life. The first clinical signs appear during the first month of life in 95% of cases and usually consist of tearing and debris on the eyelashes ("mattering"). Mucopurulent eye discharge occurs commonly in infants with CNLDO and, in the absence of other signs of infection, suggests bacterial overgrowth in the stagnant tear pool of the lacrimal sac.
This study investigates whether early administration of Euphrasia eye drops (Weleda AG, Arlesheim) in preterm neonates presenting with first ocular discharge with or without tearing and reddened eye fosters the resolution of the ocular discharge and reduces the need for topical antibiotic therapy.

Comparison between patients with nasolacrimal duct obstruction and healthy patients and the influence of their bacterial flora on the corneal epithelium.
To compare the clinical effects between the silicone nasolacrimal intubation under nasaendoscopy and dacryocystorhinostomy on patients with lacrimal duct obstruction.
The aim of this study is to compare results of endoscopy assisted nasolacrimal probing with the standard simple probing in cases with congenital nasolacrimal duct obstruction . Furthermore...
The purpose of this study is: To determine the cost-effectiveness of treating NLDO using immediate office probing compared with deferred probing in a facility setting. As part of the prim...
To determine whether there are common factors that may help predict if a child is at a higher risk for surgical failure for nasolacrimal duct obstruction.
To investigate longitudinal changes in risk factors for amblyopia in children treated with congenital nasolacrimal duct obstruction (CNLDO).
To determine the effect of probing for congenital nasolacrimal duct obstruction in children older than 2 years.
Epiphora is a common presenting symptom of nasolacrimal obstruction. Determining the level of nasolacrimal obstruction will influence the choice of management and can be aided by lacrimal imaging. Thi...
To define the microbiological features of dacryocystitis in childhood.
Interference with the secretion of tears by the lacrimal glands. Obstruction of the lacrimal sac or nasolacrimal duct causing acute or chronic inflammation of the lacrimal sac (DACRYOCYSTITIS). It is caused also in infants by failure of the nasolacrimal duct to open into the inferior meatus and occurs about the third week of life. In adults occlusion may occur spontaneously or after injury or nasal disease. (Newell, Ophthalmology: Principles and Concepts, 7th ed, p250)
A tubular duct that conveys TEARS from the LACRIMAL GLAND to the nose.
Surgical fistulization of the lacrimal sac for external drainage of an obstructed nasolacrimal duct.
A group of inherited ectodermal dysplasias whose most prominent clinical feature is hypertrophic nail dystrophy resulting in PACHYONYCHIA. Several specific subtypes of pachyonychia congenita have been associated with mutations in genes that encode KERATINS.
