Abstract :

Aim : To study the effectiveness of the two procedures Dacrocystography and Dacryoscintigraphy for diagnosing of blockage of Nasolacrimal Duct system.

Methods and Material : The prospective study included 33 patients with 40 eyes and was carried out for 1 year at our tertiary care teaching hospital. Patient with unilateral/bilateral epiphora were selected for both the tests after screening them for nasolacrimal duct system block by sac syringing. Other causes of epiphora were excluded. Nuclear scintigraphy using technetium 99 DTPA was performed followed by dacrocystography using water soluble dye in all patients.

Results: Scintigraphy showed 92.68% positive results and 7.31 % negative (false negative) for the block and dacrocystography gave 78.04% positive and 21.95 % negative(false negative).

Conclusion: Nuclear scintigraphy can be used effectively as a valuable diagnostic tool for diagnosing functional and mechanical obstruction in patients before doing a Dacrocystorhinostomy and can be used as first line of investigation for diagnosis.
