DIAGNOSTIC TEST Flashcards
it is used to assess the presence or absence of adequate lacrimal outflow
Dye Disappearance Test
this test is ideal for children
Dye Disappearance Test
What type of solution is used during the Dye Disappearance Test (DDT)?

conjunctival fornices; cobalt blue filter
(Dye Disappearance Test) persistence of significant dye over ___________ period
5-minutes
(Dye Disappearance Test) asymmetric clearance of the dye from tear meniscus over a ________ period
5 minute
investigates the lacrimal flow under normal physiologic conditions
Jones I Test/ Primary Dye Test
(Nonphysiologic Jones II Test)
the examiner instills fluorescein to the conjunctival fornices and recovers it in the _______ nasal meatus by passing a cotton-tipped applicator into the nose at ________
inferior; 2 and 5 minutes
determine the presence or absence of fluorescein in the irrigating saline fluid retrieve from the nose
Nonphysiologic Jones II Test
it is done following an unsuccessful Jones I Test
Nonphysiologic Jones II Test
(Nonphysiologic Jones II Test)

(nonphysiologic Jones II Test)
clear solution: ______________
