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...

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...

Valerie A R Juniat, Saul Rajak
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...
