open access: yesBMC Ophthalmology, 2022
Background Acquired nasolacrimal duct obstruction is a blockage of the lacrimal outflow system usually caused by local nonspecific inflammation of the lacrimal sac and the nasolacrimal duct.

Congenital Fistula of Lacrimal Duct [PDF]

open access: yesBritish Journal of Ophthalmology, 1956
CONGENITAL fistula of the lacrimal duct is very rare, and is usually associated with other congenital anomalies (Duke-Elder, 1932, 1952; Gray, 1949; Spaeth, 1948). The epithelium of the ducts and alveoli of the lacrimal gland is derived from a series of ectodermal invaginations in the region of the superior conjunctival fornix.

Lacrimal Gland Microenvironment Changes After Obstruction of Lacrimal Gland Ducts

open access: yesInvestigative Opthalmology & Visual Science, 2022
To investigate microenvironment changes of the lacrimal gland after obstruction of lacrimal gland ducts.The ducts of rat exorbital lacrimal gland were ligated by sutures for different durations. After that, the sutures in some animals were released, and they were observed for 21 days to evaluate the recovery of the lacrimal gland.

Characteristic and Correlation Between TIME and Complication After Destructive Eye Procedure Patient at Plastic and Reconstruction Division Sanglah Hospital\u27s Eye Clinic Bali-Indonesia [PDF]

open access: yes, 2012
Destructive eye procedure can be carried out by enucleation, evisceration and excenteration. Some efforts have been developed to reduce the complications, but it still occur within several years after the operation.

Bacteriology of lacrimal duct obstruction in adults [PDF]

open access: yesBritish Journal of Ophthalmology, 1997
To determine the current bacteriology of lacrimal duct obstruction (LDO) and to relate the bacteriological findings to the type of symptoms.127 samples were obtained from the lacrimal sac in 118 consecutive adult patients with LDO, including nine bilateral cases.Altogether, 156 isolates were recovered from the 127 samples cultured.

Approximate One-Dimensional Models for Monoenergetic Neutral Particle Transport in Ducts with Wall Migration [PDF]

open access: yesJournal of Computational and Theoretical Transport 46.4 (2017): 242-257, 2016
The problem of monoenergetic neutral particle transport in a duct, where particles travel inside the duct walls, is treated using an approximate one-dimensional model. The one-dimensional model uses three-basis functions, as part of a previously derived weighted-residual procedure, to account for the geometry of particle transport in a duct system ...

Numerical simulation of sound propagation in and around ducts using thin boundary elements [PDF]

open access: yesJ. Sound Vibr. 534 (2022), 117050, 2022
Investigating the sound field in and around ducts is an important topic in acoustics, e.g. when simulating musical instruments or the human vocal tract. In this paper a method that is based on the boundary element method in 3D combined with a formulation for infinitely thin elements is presented.
