Its been 8 days since you first posted Stumpy, If its getting worse and the vets too far,
maybe there is somebody in your area who keeps them and can show you how to safely flush the eyes.
I asked you before to describe/take photos of its cage furnishing/position and the room in general to determine if environmental factors are causing it.
Once airborn or cage debris is ruled out, your only option is making the trip to the vet.
Why not ask a closer vet if they can assist you to flush the eyes with saline?
Im sure if you ask politely and explain the circumstance, they will willing to do so, if only out of curiosity and the novelty of an exotic patient.
Clearly this is bothering you a great deal, its time to take the initiative mate, there is really no other/further advice the forum can offer you now.
Guessing and experimental remedies will only continue to frustrate you.
