Answer

A Jones II dye test is used to determine the presence or absence of anatomical obstruction of the nasolacrimal outflow system.

A positive Jones II dye test (colored fluid from the nose) indicates a patent system anatomically.

In light of a negative Jones I dye test, a positive Jones II dye test indicates either partial obstruction of the nasolacrimal system or a false-negative Jones I test.

A negative Jones II eye test (clear fluid from the nose) indicates functional blockage of the nasolacrimal system. This is common with horizontal laxity of the lower eyelid or flaccidity of the canalicular system.

If no fluid can be irrigated with the Jones II test, complete nasolacrimal obstruction is present.
