The nasolacrimal duct carries excess tears from the eye into the nose. If you have a very open system and force pressure back the reverse direction it is possible to eject fluid back up the nasolacrimal duct out onto the eye. I even saw it done once on Letterman Show.

I have just finished reading about the person blowing their nose and having fluid come out. I started with a cold in October which progressed to asthmatic bronchitis. I still have not fully recovered as I am still coughing and blow my nose frequently. I also wheeze. I too, have fluid coming from the eye when I blow my nose. Should I see my doctor again? Thank you! M.T.
Just watch out when blowing nose. Doesn't need to be treated - it is just a variation of normal.

So is it okay for fluid to eject backward through the tear duct or does it need to be fixed or treated?
