Dacryocystorhinostomy (DCR) surgery could be a method that points to dispose of liquid and mucus retention inside the lacrimal sac, and to extend tear waste for alleviation of epiphora (water running down the confront). A DCR strategy includes expulsion of bone adjoining to the nasolacrimal sac and consolidating the lacrimal sac with the horizontal nasal mucosa in arrange to bypass the nasolacrimal channel hindrance. This permits tears to deplete straightforwardly into the nasal depression from the canaliculi by means of a modern lowresistance pathway.

Conjunctivodacryocystorhinostomy or CDCR could be a surgical method where a unused section is made for waste of tears from the conjunctival cul-de-sac specifically into the nasal depth. The strategy can be performed through an outside approach (outside CDCR), an endoscopic approach (endoscopic CDCR), or a negligibly obtrusive approach (MICDCR) or diode laser-assisted (LCDCR) and endoscopic conjunctivorhinostomy (CR) without a DCR. In spite of the fact that the strategy is valuable with a victory rate floating around 90%, huge arrangement have appeared two major complications, specifically, expulsion of the tube extending from 28% to as tall as 51% and tube malposition extending from 22 to 28%. In arrange to dodge these complications, various alterations of the bypass tube have been distributed counting extra ribs, wide average closes, angulated tubes, and permeable polyethylene-coated tubes.

Conjunctivodacryocystorhinostomy CDCR with the addition of a glass (Jones) tube changed the administration of canalicular obstacle. Sometime recently this advancement, administration alternatives for proximal obstacle included canalicular stenting with polyethylene tubes or reiterative examining, both of which had destitute victory rates.

At first, CDCR was performed as an outside strategy by way of a average canthal entry point with cautious situating of a glass (Jones) tube at the locale of the caruncle. Right now, endoscopic-assisted strategies are frequently utilized, coming about in superior situating of the tube, shorter working time, and less dying [1,2].

Canalicular obstacle may be caused by injury, surgery, systemic chemotherapeutic specialists (such as fluorouracil or docetaxel), topical antiglaucoma drugs (counting dorzolamide, pilocarpine, and timolol), and antiviral drops (such as idoxuridine and trifluridine).

Canalicular obstacle can be caused by a large number of issues counting injury, disease or cicatricial conditions. In cases were systemic chemotherapeutic specialists are utilized, broad fibrotic changes with prove of keratinization and checked epidermalization of the surface epithelium [3].

In cases were the canalicular stenosis is auxiliary to chemotherapeutic specialists, bicanalicular silicone intubation early within the course of malady may anticipate extra scarring and decrease the require for CDCR [4].

Extrusion of the tube is the most frequent complication, with many requiring additional revision within 5 years. Malposition, infection and obstruction of the tubes have also been reported, and remain lifelong possible risks [5].
