My Kenna has this condition.
After trying many drops and things to try to kickstart her tissue into producing tears, we decided to have an operation where the opthamologist (doggie not human, lol!) re-directed a saliva gland from her mouth to her eye for moisture! A few set-backs, but very successful! She was only 9 mos old at the time and that was over a year ago. Her case was very severe, there is a test the vet can do to see how many tears are actually produced in a given time. Kenna didn't produce any at all. She also had the white/grey color on her eye as my vet said everytime she blinked it was like sandpaper, owch! This was from the eyelid rubbing on the cornea...She developed a corneal ulcer after the operation as well, just from swelling and turning her eyelashes under. It's all good now, thank goodness!
Your vet will probably refer you to the specialist in your area. Good luck! I know exactly what you are going through! Shelley
