I am writing this because my leaks are very improved with my new mask although some of the time I don't have much breathing room between my leakage rate and 24 l/min. I have been able to determine fairly confidently that the remaining leaks are from the tear ducts in my eyes. It does not bother me much and does not awaken me much.
Here is my only real concern. Has anybody who experiences this type of leakage discussed this with an ophthalmologist concerning any long term negative effects on the eyes or does anybody know of any long term negative effects on the eyes?
The ducts at nasal junction are drains into the sinuses. Yes, they can leak air.
The leak rate should be very small compared to the intentional mask leak rate (flush rate.)
I do notice some crud in my eyes in the morning.
I am followed by an ophthalmologist -- just saw him Wednesday.
He's been following me for a decade; and not seen any deleterious effects.

I certainly have experience tear duct leakage (but not from the CPAP). Sometimes when I equalize my inner ear by holding my nose and blowing gently, a tiny stream of air will come through my tear duct.
justMongo is almost certainly correct: If this leak is not sufficient to drive you insane or even keep you awake then it is likely VERY SMALL compared to the designed and intended mask leak.
Our machines are able to handle quite a bit more than the designed leak.
For small leaks like this, the key for therapy is: Does it disturb or prevent your sleeping?
Asking a physician if it can cause problems is certainly a reasonable thing to do.
For myself, if it didn't bother me, I would likely wait for a regular visit to one of my docs -- as long as there were no other deleterious effects.
