Welcome! My name isXXXXX am a 2003 graduate, and currently a Medical Director of a veterinary hospital.
I am sorry to hear about this concern for Mags.
Very interesting question.
First, I think we both can agree that the type of discharge coming out of the eye is suggestive of an infection. But, it has happened before.
So, we must be suspicious for a few things.
Is it a repeat injury? Perhaps allergy related. Or, something else.
When it happened the first time, and definitely the second occurrence, the vet should have been starting some basic testing.
1. A basic eye stain test, to ensure there is no corneal ulcer/scratch on the surface of the eye. This is extremely routine and surprised they haven't recommended it yet.
2. A schirmer tear test. Sometimes, when dry eye, also known as keratoconjunctivitis sicca starts, it will be only one eye.
The most common eye tests performed by your veterinarian:Eye Stain Test for Ulcers
.Tear test for Dry Eye
.Glaucoma Eye Pressure Test
A common deeper issue can be when there are eyelid or eyelash problems causing chronic irritation to the eye.
Here are some of the more common eye conditions (in no particular order):Corneal Ulceration
.KCS - Dry Eye
So, it may be well worth consulting a new vet for a second opinion. If your interested, and they aren't too far, you can even just go straight to a opthalmologist specialist for a consult. Find a Ophthalmologist
