Objectives-To find out various causes of epiphora, level and type of block in lacrimal passage, lacrimal pump function, causes of failed dacryocystorhinostomy. Materials and Methods-Dacryocystographywas done in 100 eyes of 83 patients of epiphora and divided in three groups , Epiphora with patent lacrimal system, non patent lacrimal system, and residual epiphora after the operation of dacryocystorhinostomy. Dacryocystography was performed by using 0.5-1 ml of urograffin 76% with the lacrimal cannula and X-ray during forceful injection of the dye. A-P lateral & PNS waters view (magnified) were taken by 500 na X-ray Machine. Results-Incidence of epiphora was 41% Right eye, 39% Left eye, 20% both eyes. Male female ratio, 16:84. All age groups are affected almost equally with slight higher incidence in 6 th decade in female.On the basis ofdacryocystography,Complete block in 60% cases, partial block in 9% cases,and no block was observed in 31% cases. Level of block was at Canalicular in 3%, at common canalicular in 7%, at lacrimal sac-duct junction in 84% and at lower end of nasolacrimal duct in 6% of cases. Prevalence of associated ENT disorders about in 24% and atonic sac in 4 cases. Conclusions-Dacryocystography isa simple, easy, cheap, safe and less time consuming investigation, which can be done even at most peripheral level of health services where X-ray facilities are available.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
