The lacrimal gland secretes tear fluids to ocular surface, which plays an indispensable role in maintaining the health of the ocular epithelia and protecting the ocular surface from the external environment. The dysfunction of the lacrimal glands causes dry eye disease due to a reduction in tear volume. The dry eye disease is becoming a popular public disease, for the number of patients is increasing, who have subjective symptom and loss of vision, which affect the quality of life. Inflammatory change in the damaged lacrimal gland has been reported; however, a major challenge is to establish a simple animal model to observe the changes...

BACKGROUND: Epiphora secondary to nasolacrimal duct obstruction is common in the pediatric age group. The mainstay treatment among these young patients has been conservative. Once epiphora becomes recalcitrant, however, an external or an endonasal approach is considered. OBJECTIVE: Endoscopic dacryocystorhinostomy (EDCR) entails creating an opening from the lacrimal sac directly into the nasal cavity to counteract nasolacrimal duct obstruction. We reviewed the literature to determine the effectiveness and the safety of primary EDCR to treat pediatric nasolacrimal duct obstruction...

The treatment of midfacial tumours with radiotherapy, chemotherapy and radio-iodine can cause nasolacrimal duct fibrosis resulting in epiphora. Nasolacrimal patency can be maintained by stenting. We report our experience of prophylatic Nunchaku stent insertion in 5 patients prior to midfacial radiotherapy. Four out of 5 patients (80%) had patent nasolacrimal ducts without any symptoms of epiphora following removal of the stents. One patient was initially asymptomatic with patent nasolacrimal duct, but subsequently developed epiphora...

Aqueous tear-deficient dry eye is a multifactorial chronic disorder in which the lacrimal glands fail to produce enough tears to maintain a healthy ocular surface. The existence of lacrimal gland stem/progenitor cells was proposed in several species, yet their origin and characteristics are not very clear. Here, we investigated the presence of resident progenitor cells and their regenerative potential in a rabbit model with lacrimal gland main excretory duct ligation-induced injury. The ligation-injured lacrimal glands temporarily decreased in weight and had impaired tear secretion...

BACKGROUND: Congenital nasolacrimal duct obstruction (NLDO) is a common condition causing excessive tearing in the first year of life. Infants present with excessive tearing or mucoid discharge from the eyes due to blockage of the nasolacrimal duct system, which can result in maceration of the skin of the eyelids and local infections, such as conjunctivitis, that may require antibiotics. The incidence of nasolacrimal duct obstruction in early childhood ranges from 5% to 20% and often resolves without surgery...

Mammalian tears are produced by lacrimal glands to protect eyes and may function in chemical communication and immunity. Recent studies on the house mouse chemical signalling revealed that major urinary proteins (MUPs) are not individually unique in Mus musculus musculus. This fact stimulated us to look for other sexually dimorphic proteins that may-in combination with MUPs-contribute to a pool of chemical signals in tears. MUPs and other lipocalins including odorant binding proteins (OBPs) have the capacity to selectively transport volatile organic compounds (VOCs) in their eight-stranded beta barrel, thus we have generated the tear proteome of the house mouse to detect a wider pool of proteins that may be involved in chemical signalling...

Background In a retrospective study, the success rates of laserdacryoplasty using a diode laser were defined and compared to success rates using an erbium : YAG laser. Using a diode laser at a wave length of 980 nm, thermal destruction of tissue leads to recanalization. Using an erbium : YAG laser at a wave length of 2940 nm, recanalization of punctual stenosis is achieved by formation of a cavitation bubble in a closed system. Materials and Methods 94 patients (64 women, 30 men, mean age 60.8 years) with 107 absolute lacrimal duct stenoses who were treated by laserdacryoplasty using a diode laser were included in a retrospective study...
