A 42-years-old male presented with left medial canthal swelling, accompanied with only mild epiphora. There was no history of dacryocystitis, mid-facial trauma, surgery, or bloody tears. On examination, there was an immobile, subcutaneous, non-inflammatory mass below the medial canthal tendon. Lacrimal irrigation showed blockade at the nasolacrimal duct. A computerized axial tomography (CAT) scan revealed a non-enhancing, low-density, cystic lesion at the inferomedial margin of the orbit. There were no signs of bony erosion, consistent with idiopathic acquired dacryocystocele...

Importance: Endoscopic dacryocystorhinostomy (EN-DCR) is emerging as the preferred procedure in the management of nasolacrimal duct obstructions. However, its safety and long-term efficacy in the setting of acute dacryocystitis with lacrimal sac abscess have not been well studied. Objective: To compare outcomes of EN-DCR as primary treatment with EN-DCR as a secondary treatment after percutaneous drainage of lacrimal sac abscess in acute dacryocystitis. Design, Setting, and Participants: This randomized clinical trial was conducted from October 1, 2012, to October 31, 2015, at a tertiary ophthalmic center...

J Adams, C P Schaaf
Alacrima, the lack of tears, is a rare clinical finding that has been reported as a feature of multiple genetic disorders and can serve as a diagnostic clue to some rare conditions. Causes of alacrima range from absence/hyposecretion of tears to agenesis or improper development of lacrimal gland ducts and associated structures. There are 13 known heritable disorders featuring varying degrees and causes of alacrima. Some manifest only the congenital absence of tears, while others affect multiple organ systems and may involve severe developmental delay, intellectual disability, and potentially life-threatening autonomic dysregulation...

BACKGROUND: Lymphomas of the lacrimal sac are rare, accounting for less than 10% of lacrimal sac malignant tumours. They may present with symptoms typical of secondary acquired nasolacrimal duct obstruction and are thus often misdiagnosed. METHODS: Case series and literature review. RESULTS: Herein we describe 3 cases of chronic lymphocytic leukaemia (CLL)/small-cell lymphocytic lymphoma (SLL) of the lacrimal sac with immunohistochemical and in 1 case molecular confirmation...

Today's gold standard in the treatment of infrasaccal primary acquired nasolacrimal duct obstruction (PANDO) is external dacryocystorhinostomy (DCR), a relatively invasive procedure that can be performed after failure of recanalizing treatments. However, with progress in the field of diode laser technology, new approaches have emerged. Laser-assisted transcanalicular DCR with subsequent bicanalicular silicon intubation is a new option showing great promise as a viable minimally invasive procedure. Under permanent endoscopic visual control from the nasal cavity, a diode laser fiber is inserted into the lacrimal sac and laser energy is applied to create a bony ostium between the lacrimal sac and the nasal cavity...

We prepared magnesium hydroxide (MH) nanoparticles by a bead mill method, and investigated whether the co-instillation of MH nanoparticles improves the low transcorneal penetration of water-soluble drugs, such as the anti-glaucoma eye drug timolol maleate (TM). MH particle size was decreased by the bead mill treatment to a mean particle size of 71 nm. In addition, the MH nanoparticles were highly stable. Next, we demonstrated the effect of MH nanoparticles on the corneal surface. MH shows only slight solubility in lacrimal fluid, and the instillation of MH nanoparticles for 14 days did not affect the behavior (balance of secretion and excretion) of the lacrimal fluid in rabbit corneas...

INTRODUCTION: Acute dacryocystitis is an uncommon but serious condition in infants and needs immediate treatment. Although, medical management with systemic antibiotics remains the mainstay of initial treatment, there are recent studies justifying simultaneous Naso Lacrimal Duct (NLD) probing with acceptable success rate. AIM: To assess the success rate of probing in the management of infantile acute dacryocystitis and to analyse the factors affecting it. MATERIALS AND METHODS: A prospective interventional study was designed and infants presenting with acute dacryocystitis with or without complications like dacryocystopyocele/ lacrimal abscess/preseptal cellulitis at a Tertiary Eye Care Centre from May 2014 to April 2016 were enrolled...

The nasolacrimal duct (NLD) connects the orbital (often associated with the Deep Anterior Orbital gland: DAOG, a.k.a. Harderian gland) and nasal regions in many tetrapods. Adult cetaceans are usually said to lack an NLD, and there is little agreement in the literature concerning the identity of their orbital glands, which may reflect conflicting definitions rather than taxonomic variation. In this study we examined an embryological series of the pantropical spotted dolphin (Stenella attenuata), and report numerous divergences from other tetrapods...

NUT midline carcinomas (NMCs) are rare, poorly differentiated tumors with aggressive biological behavior and a characteristic molecular signature. Availability of NUT antibody has facilitated diagnosis of NMC without molecular testing. We report a series of head and neck NMCs diagnosed using NUT IHC at our institute, including one case with an unusual course. Immunohistochemistry for NUT was performed in nasal and sinonasal tumors with diagnoses of undifferentiated carcinoma, poorly differentiated squamous cell carcinoma and malignant neoplasm, not otherwise specified, to identify cases of NMC...

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...
