Order some Terramycin eye antibiotic from Amazon or ask your feed store for it. A dab in each eye two times a day in addition to daily flushing with eye saline wash.
It does kind of look like there was a hemorrhage inside the eye or the brain. I have seen similar red eyes in a couple of out dogs who had bleeds inside the eyes. One was blind, and the other large dog had had a brain bleed.
