To evaluate the excretory lacrimal pathways (ELP) by scintigraphy and dacryocystography, comparing both methods.


We studied 34 patient 5 (68 lacrimal systems) from the Lacrimal Pathway Outpatient Clinic who were submitted to dacryocystography (DCG) and lacrimal scintigraphy (LS).


It was observed that 61.8% of right ELP and 55.9%o of left ELP investigated did not have obstruction by DCG. 73.5%o of these patients had radiological signs suggestive of cornetus hypertrophy. The LS showed no obstruction in 29.4%c of right ELP and 23.5% of left ELP. However, 32.3%c of the ELP obstructions were only detected by scintigraphic examination.


The authors concluded LS to be an important examination for the diagnosis of obstruction of the lacrimal system, mainly in the carriers of functional obstruction.
