Blocked Tear Duct Nasolacrimal Duct Obstruction The nasolacrimal duct is the major tear duct of the whole lacrimal drainage system. it can be obstructed, and usually in its lower third segment. the incidence of nldo is higher in women, increasing after the age of 40 years old. up to about 70% of cases of nldo can develop acute dacryocystitis (inflammation and infection of the tear sac). Dacryocystorhinostomy (dcr) dcr is a procedure performed for the treatment of tearing (epiphora) due to blockage of the nasolacrimal duct. it creates an ostium between the tear sac and the nasal cavity by removing the mucosa and bone layers between them. there are two main approaches to a dacryocystorhinostomy external and endoscopic.
Tearing Epiphora Nasolacrimal Duct Obstruction Singapore A simple but very effective way to assess for nasolacrimal duct obstruction is to evaluate the size of the tear meniscus. burkat and lucarelli 1 demonstrated that the height of the tear meniscus, measured by slit lamp examination, was a statistically useful indicator for nasolacrimal duct obstruction. they found that the median tear level in. What causes tearing? abnormal over production of tears (hyperlacrimation) dry eye; irritative eye disorders: allergic eye disease, mebomian gland dysfunction, inflammatory eye disorders aberrant regeneration (abnormal neuro stimulation from recovery of facial nerve palsy) tear drainage obstruction punctal stenosis; nasolacrimal duct obstruction. Epiphora is a very common complaint, and nasolacrimal duct obstruction (nldo) is the most common cause of persistent epiphora. the incidence of nldo is reported as 20.24 per 100,000. in this incidence study, ndlo accounted for 31.8% of all chronic epiphora and 67.6% of all tear drainage pathway obstructions. The lacrimal sac region should be massaged, and if fluid or mucopurulent discharge results, then a nasolacrimal duct obstruction is present. the examination then can be aided with the slit lamp. the tear lake, the level of tears at the junction of the lower eyelid and globe, should be evaluated.

Epiphora is a common problem encountered by eye care providers and is seen in both children and adults. nasolacrimal duct obstruction (nldo) is a frequent cause of persistent epiphora and can be due to congenital or acquired changes in the nasolacrimal duct system. treatment includes conservative methods as well as surgical methods to restore the natural nasolacrimal duct system or to bypass. Nasolacrimal duct obstruction (nldo) or dacryostenosis is the most common disorder of the lacrimal system.[1] approximately 6% to 20% of newborns patients present with some symptoms.[2] typically, nldo presents more often in the first weeks or months of life with symptoms beginning when normal tear production occurs, presenting as excessive tearing and ocular discharge. erythema of the.
