The aim of our study was to evaluate the characteristics and surgical outcome in patients who underwent external DCR, which is considered a standard treatment for NLDO.
There was no significant association of NLDO and dacryocystitis with other systemic illnesses including diabetes, hypertension and thyroid disorders.
In conclusion external DCR still remains the treatment of choice for NLDO in our setup with very good postoperative results in patients with or without previous history of dacryocystitis.
Results: The overall success rate of Nasolacrimal intubation as a primary treatment of congenital NLDO was 89% in children between 12 to 48 months age (mean25.
Nasolacrimal intubation has been popular since its introduction in the late 1960s for the treatment of persistent NLDO after failed probing.
We observed the out come of Nasolacrimal intubation as a primary treatment of NLDO in children upto 4 years of age with planned tube retention for 3-6 months.
The eligibility criteria included children aged 12 to 48 months with NLDO, onset of NLDO symptoms prior to 6 months of age, presence of epiphora, increase tear film, and/or mucopurulent discharge in the absence of an upper respiratory infection.
The study outcome visit was timed 1 month after the date of tube removal and clinical examination was performed for the presence or absence of the three clinical signs of NLDO (epiphora, increase tear film or mucous discharge).
Nasolacrimal duct intubation was performed as a primary treatment for NLDO in 65 eyes of 59 patients.
Treatment was classified as successful when all three clinical signs of NLDO such as epiphora, mucous discharge and increase tear lake were absent and no additional surgery was required.
In all patients compression over the lacrimal sac to look for tenderness and regurgitation on digital pressure (ROPLAS) and probe test for ROPLAS negative cases to evaluate for hard and soft stop assessed to diagnose NLDO.
Iatrogenic causes of NLDO also may follow orbital decompression surgery, paranasal, nasal, and craniofacial procedures.
