Chronic infection may also lead to formation of dacryoliths and subsequent obstructive signs and symptoms.
(6,7) Canaliculotomy and curettage of the dacryoliths are the gold standard in treatment.
Six patients had dacryoliths. Lacrimal lavage through the unaffected canaliculus was patent in all patients.
A monitor shows the images obtained through the little endoscope in the probe, while an irrigation cannula and a laser or microdrill for treating stenoses and dacryoliths (stones in the lacrimal sac) are available options.
(1) In the remaining 60% of patients, there appeared to be no obvious preoperative cause of obstruction; of these patients, 65% were found to have dacryoliths at surgery.

Advantages of Ext DCR are good intraoperative visibility inside the lacrimal sac allowing unrestricted inspection of the internal punctum and the lacrimal sac mucosa, the possibility of detecting lacrimal sac for pathology (tumours, dacryoliths) and ease of suturing mucosal flaps.
Actinomyces species were most commonly isolated (75%) and dacryoliths were present in six of the cases.
The insufficient drainage is due to either congenital causes like punctal atresia, diverticulum or fistula from sac to nose or cheek, Nasolacrimal Duct Obstruction (NLD), agenesis or acquired causes (1) like punctal stenosis due to age-related atrophic processes, chronic disease, dacryoliths, allergy, systemic chemotherapeutic agents, postherpetic infection (Herpes simplex, varicella zoster), bacterial infection (Actinomyces, Chlamydia), Wegener granulomatosis, sarcoidosis, hay fever, atopy, etc.
The Main objective of the present study is to review the literature about the chemical composition and the formation of dacryoliths. Dacryoliths are calculi of the lacrimal system observed incidentally during dacryocystorhinostomy.
