[Dacryocystography and dacryoscintigraphy in diagnosis of naso-lacrimal duct obstruction].
OBJECTIVE
To find the right diagnostic test through checking the drainage of lacrimal ducts.


METHODS
Dacryocystography of lacrimal ducts was performed in 25 patients by using 0.5-1 ml of Lipidiol and conducting X rays in different head positions--3-4 photograph in A-P projection (exposition's parameters 85-90 kV and 12-15 mAs, distance lamp-table: 100-130 cm, Philips Diagnose 93). For stereo estimation--2 oblique photographs of head, deviated at 45 towards central body line. Patient is brought on vertical position and after 5 minutes radiography in A--P projection can show remaining contrast in lacrimal duct. Dacroscintigraphy was done in 200 patients by dropping in conjunctival sac 1 drop of sterile 99mTc, in dose 3.7-7.4 MBq (100-200 uCi). The patients head is immobilized on the support, close to detection head of gamma camera (ediso Nucline TH) with LEHR. Distribution of this drug was visible on the monitor and saved in the computer's memory. Data was registered during 10 minutes, summed up into end picture and then evaluated by sight.


RESULTS
Many authors consider dacryoscintigraphy and dacryocystography as methods of choice in establishing correct diagnosis. High sensitiveness and mutual completion of both methods lets us quickly explain the reasons of epiphora and settle further management.
