We established a chronic dacryocystitis model by injecting of 0.05, 0.1, and 0.15 ml self-curing resin via the lacrimal punctum in rabbits. Animals were randomized into four groups (n = 11 animals/group). The control group received 0.15 ml normal saline. Within three months postinjection, epiphora and eye discharge were observed. At the 90th day postlacrimal passage irrigation, CT dacryocystogr...

OBJECTIVES To evaluate a new technique of modified endoscopic dacryocystorhinostomy involving the creation of a large posterior flap at the lacrimal sac and to compare its success rate with that of the conventional endoscopic method of excising the entire medial lacrimal sac wall as a surgical treatment for epiphora caused by nasolacrimal duct obstruction. DESIGN Retrospective, interventional...

Dacryocystitis is inflammation of the lacrimal sac. Chronic dacryocystitis due to obstruction of nasolacrimal duct affects all ages and had been described by Galen as early as the second century BC.! It is most frequently seen in infants and in middle aged females. In the congenital type it is due to non-canalisation of the nasolacrimal duct and 50% undergo resolution by 6 months of age? Dacryo...

BACKGROUND Epiphora constitutes one of the major and very common problems in all age groups. Recent developments in ophthalmology such as balloon dilatation, stent implantation, laser therapy and endoscopy of the lacrimal drainage system raise the need for a detailed anatomical knowledge of this system. It is also important for formulation of principles and techniques in the management of acrim...

A 66-year-old man presented with a slowly enlarging, nontender left orbital mass of 2 months' duration. CT and MRI showed a left lacrimal gland mass with enhancement and internal irregularity of cystic structures. Histopathologic analysis of the biopsy specimen revealed a squamous cell carcinoma arising from an epithelium-lined cyst. The patient underwent left orbital exenteration followed by r...

OBJECTIVE To assess the results of microsurgical endonasal dacryocystorhinostomy with long-term insertion of single or double bicanalicular silicone tubes in canalicular (presaccal) and ductal (postsaccal) stenosis of the nasolacrimal duct system. DESIGN Retrospective follow-up of case series between 1992 and 1996. PATIENTS Thirty-eight patients were included in the study: 19 with ductal st...

AIM To report the outcomes of endoscopic guided anterograde 3 mm balloon dacryoplasty with silicone intubation in patients with acquired partial nasolacrimal duct obstructions in adults. METHODS Retrospective case series, included 21 eyes with partially obstructed nasolacrimal ducts of 12 patients. All the 21 ducts were initially probed and the probe confirmed with an endoscope in the inferio...
