The eye stain test, would also help to check for any corneal ulcers, like a scratch on the surface of the eye ball.
A schirmer tear test needs to be done. I know that sounds awkward, because there is a lot of discharge in the eyes. A tear test evaluates for KCS (keratoconjunctivitis sicca) or dry eye. KCS, is when the normal "ingredients" that make up tears are missing. This results in a chronic eye discharge that is thick and irregular and requires a specific type of a eye drop and is life long.

.Glaucoma Eye Pressure Test
The eye stain test will be important for this breed and at this age. Make sure you do not put any eye drops or saline in the eyes before this vet visit.
Also, the vet needs to look closer at the eyelids. Sometimes, eyelid problems can cause a problem with chronic discharge. That includes issues like distichia, where a irregular eyelash is pointing inward and repeatedly rubbing against the eyeball.
Common causes for any type of eye discharge include:
- Corneal ulceration (i.e. eye scratch, trauma to surface of eye)
- As a component of an upper respiratory infection
- Eyelid problems or irregular eyelashes
Sarah, I would even consider getting a second opinion, or if available in your area, request a consult with a veterinary ophthalmologist.
I hope that information has been helpful.
