Functional lacrimal obstruction is a rare physiologic dysfunction of the lacrimal drainage system without any mechanical obstruction. Twelve eyes of 9 patients were diagnosed by syringing, dacryacystography, and lacrimal scintigraphy. Normal drainge pattern was noticed in syringing and in the initial film of dacryocystography. However slow or non-functioning drainge was disclosed in the delay film of dacryocystography and lacrimal scintigraphy. The causes of functional problem were facial nerve palsy, trauma and idiopathic. Conjunctivodacryocystorhinostomy was performed in all 12 eyes with satisfactory results.
Key Words: Functional lacrimal duct obstruction;Dacryocystography;Conjunctivodacryocystor hinostomy
