This study aimed to examine the rate of symptomatic improvement of congenital nasolacrimal duct obstruction (CNLDO) in Japanese infants treated with conservative management within the 1st year of age. Thirty-five lacrimal ducts in 27 patients diagnosed with CNLDO were included in the study. During the observational period, lacrimal ducts were massaged. As well, antibiotic eye drops, to be admin...

A wide array of pathogenic factors has been associated with lacrimal drainage system obstruction including inflammatory conditions originating from the eye, conjunctiva, lacrimal mucosa, nose and paranasal sinuses; trauma; congenital abnormalities; radiotherapy and neoplasms. Inflammatory conditions initially cause lac-rimal mucosal swelling but may lead to fibrotic narrowing or obstruction of ...

The dacryocystocele represents a rare congenital anomaly in the medial region of the orbit caused by distal obstruction (Hasner valve) and proximal (valve Rosenmüller) of the lacrimal system causing dilation of the lacrimal sac. Mucocele is called when the content is mucus and amniocele when the content is filled with amniótico fluid. The incidence is only 0.1% in children with nasolacrimal duc...

AIM To evaluate a new approach of recanalisation of nasolacrimal duct obstruction (RC-NLDO) in the treatment of the nasolacrimal duct obstruction (NLDO) and chronic dacryocystitis. METHODS 583 patients with 641 eyes suffering from NLDO and chronic dacryocystitis were enrolled in this study. The RC-NLDO was performed in 506 eyes, with 135 eyes undergoing external dacryocystorhinostomy (EX-DCR)...

The main objective of the present study was to prospectively evaluate long-term surgical success and safety in patients with nasolacrimal duct obstruction treated with a multidiode transcanalicular laser and bicanalicular silicone intubation stenting. 42 patients treated with transcanalicular laser dacryocystorhinostomy for nasolacrimal duct obstruction were prospectively enrolled. In all cases...

OBJECTIVE To assess the impact of the rate of spontaneous resolution of congenital nasolacrimal duct obstruction on the relative cost-effectiveness of deferred nasolacrimal duct probing in a surgical facility (DFPS) compared with an immediate office-based probing surgery (IOPS). METHODS Data from the literature, Medicare 2009 fee schedule, and consensus assumptions were combined to populate a...

The rabbit’s anatomy of the nasolacrimal system is unique, with a single lacrimal punctum and a tortuous nasolacrimal duct. Inflammation of the nasolacrimal duct, dacryocystitis, can be caused by primary infection with bacteria from the respiratory tract, secondary to infectious conjunctivitis or nasolacrimal duct obstruction. The latter can occur due to the rabbit’s anatomy features, the tears...

PURPOSE We report a very good outcome in a 44-year-old woman in whom cancer was missed as the cause of nasolacrimal duct obstruction and dacryocystitis and which was deemed inoperable after spreading to the cavernous sinus. CASE REPORT The patient was referred to our unit 12 months following uneventful right dacryocystorhinostomy for nasolacrimal duct obstruction. This had been complicated by...
