Hello, I'm Dr. XXXXX XXXXX and I'd like to help!
This is likely due to an infection either in the tooth roots or in the nasal sinuses. There are several types of bacteria that can do this. The one that is most well known is pasteurella. This can be quite serious in some rabbits and shoud be checked by a veterinarian.
Some vets do complete work ups for this, others try conservative treatment with antibiotics. Rabbits are sensitive to certain antibiotics so you have to be careful about what is used.
The comlete workup would include blood tests, x rays and a mouth exam under anesthesia. This is not something that you an typically treat without antibiotics.
It seems like the situation is worsening and blood is starting to leak out from the corner abscess in her (rabbit's) eye. Tomorrow is Independence day and any services will be closed. I don't know how much worse this can get and I am worried about how to approach this infection. Is there anything I can do at home while I wait for assistance from a vet? Also, about how much will it cost for the complete workup? Thank You.
