Pak J Ophthalmol Jan ;15(4):169-72.

A study of 20 patients admitted for surgery of canaliculorhinostomy was conducted In the Ophthalmology Unit of Abbassi Shaheed Hospital, Karachi, from 01-01-96 to 01-04-98. Eight patients were male l40%1 and 12 were female l60%1. All patients had troublesome epiphora. Four cases had lacrimal fistula (20%). Eight cases had lacrimal encysted mucocele (40%). All cases had one or more episodes of acute dacryocystitis. Regurgitation test was negative. Lacrimal passages were blocked at either the common canallcular level or both at the common canallcular and the nasolacrimal duct level leading to encysted mucocele. Chronic dacryocystitis was the diagnosis with fibrosis at both ends. Treatment was removal of the lacrimal sac with anastomcsis between the canalicull and the nasal mucosa by removal of the lacrimal bone. The passages were intubated by using silicone stents or tubes. Most of the cases were performed under local anesthesia. Complications: One case developed a suture abscess and one case had the tube coming out. Three cases had conjunctivitis (15%) which improved after removal of the tube. Three cases had recurrent conjunctivitis even after removal of the tube (15%). One case had persistence of epiphora after removal of the tube even though syringing showed patent passages. One case had epiphora and syringing showed blocked passages (5%).
