A study of clinico Pathological Correlation of Naso lacrimal duct obstruction

Objective: To study the age and the sex distribution among the primary and secondarily acquired Nasolacrimal duct obstruction . Methods: we conducted a prospective observational study among randomly selected 100 patients presented with epiphora to ENT department during 2year period ie; from march 2013-march 2015. After confirming presence of Nasolacrimal duct obstruction (NLDO) by opthalmologicalexamination ,theyare takenup for Endo nasalDacryocystorhinostomy and intraoperative lacrimal sac wall biopsy is taken for histopathology to identify the etiology of NLDO. Age and sex distribution among primary and secondarily acquired types of NLDO was studied . Results: Among primary and secondarily acquired variants of NLDO , it was found to be more common in females when compared to males ( male : female =1:6.13). Primary acquired duct obstruction is more common among elderly age group ( 51-60 yrs) , and NLDO is found to show left eye lacrimal system predilection (58%) when compared to right eye. Conclusion: Epiphor a due to Primary acquired naso lacrimal duct obstruction (PALDO) is commonly seen in elderly age group , and commonly associated with bilateral NLDO (30%). Among younger adults, secondarily acquired obstruction (SALDO) are common .NLDO is more common among females.
