Can an intraocular test cause damage to the eye if administered incorrectly? It's actually my dog that had the test and she left the vets with green gunk in the corner of her eyes and has a film over one eye. We did take her back to the vets and she is being treated but I need to know what has caused this as she didn't have it before her stay. She went into the vets for something totally unrelated to her eyes btw.
