DOS Times Vol. 12, No. 10 April, 2007 Congenital nasolacrimal duct obstruction is the most common cause of epiphora in children. In the majority of cases, it is due to an obstruction at the lower end of the NLD. The Ophthalmologist should have the throrough understanding of the developmental anatomy, abnormalities of the nasolacrimal system and other congenital disorders for appropriate diagnos...

aging scan showed no abnormalities. Lumbar puncture showed an increased opening pressure (225 cm H2O), but the cerebrospinal fluid showed no cells, no hypoglycorrhachia, and no elevation in the protein concentration. Treatment with ATRA was discontinued, and the APML was treated with a combination of arsenic trioxide, daunorubicin hydrochloride, and cytosine arabinoside. Over the next 6 weeks, ...

Developmental anomalies of the nasolacrimal drainage system typically manifest early in childhood with epiphora and occasionally infection. Although the majority of cases of congenital nasolacrimal obstruction resolve spontaneously with conservative medical management, certain anomalies require operative intervention. Included in this latter group are dacryocystoceles or nasolacrimal duct cysts...

The eye has two sets of structures that produce tears. Smaller tear glands help maintain a baseline level of moisture on the surface of the eye. Unfortunately, inflammatory conditions like rheumatoid arthritis, Sjogrens disease as well as aging and menopause lead to decreased tear production. As tear production diminishes, the surface of the eye starts to dry out. Further, inflammation of the o...

To compare the surgical duration and clinical outcomes of nasolacrimal recanalization versus external dacryocystorhinostomy (DCR) in the treatment of failed nasolacrimal duct intubation.This is a retrospective, comparative, and interventional study. We evaluated the outcomes of 66 consecutive patients undergoing either nasolacrimal recanalization (n = 32) or DCR (n = 34) in a tertiary lacrimal ...

AIM It appears from the literature that no standardised examination exists for patients with functional nasolacrimal duct obstruction. The role of dacryocystography and lacrimal scintigraphy was compared in the diagnosis and management of these patients. METHOD Patients who were clinically diagnosed as having unilateral or bilateral functional nasolacrimal duct obstruction were prospectively ...

PURPOSE To compare conventional and endoscopic probing for congenital nasolacrimal duct obstruction in infants. METHODS Conventional probing was performed in 22 eyes of 18 patients, age range 7-14 months (mean 11.4 months). Probing was done with intranasal endoscopic visualization in 18 eyes of 14 patients, age range 7-13 months (mean 11.2 months). All were primary probing cases. RESULTS Af...

We report the imaging features of a rare sinonasal myxoma situated over the right nasolacrimal duct in a 5-month-old male. We emphasize the importance of including sinonasal myxomas in the list of differential diagnostic possibilities when encountering a nasolacrimal gland mass in an infant, and describe the CT and MRI characteristics of this rare entity.

Observation is a simple and reliable tool with the clinician. The level of tears, position of puncta, lids and eyelashes should be noted. Obstruction of the tear drainage system can be acquired or congenital, it is important to rule out acquired causes of tearing such as corneal, lid or lash abnormalities. Lacrimal obstruction problems can be divided as related to upper (puncta to lacrimal sac)...

PURPOSE To characterize the outcomes of initial and repeated office-based probing as a primary treatment for congenital nasolacrimal duct obstruction (CNLDO) in children. METHODS The medical records of patients who underwent nasolacrimal duct office-based probing for CNLDO between March 2004 and January 2008 were reviewed retrospectively. Nasolacrimal duct probing was performed on 244 eyes fr...
