I am so sorry for your gliders and you.
Do you have any quickderm or neosporin at hand? Until you can get her to the vet, it will be good if you could apply some, but since it is so close to the eye, I am not sure how safe it will be. Also be watchful in case she tries to groom it and ends up making it worse. You may be able to make her an e-collar to help prevent this, here are instructions on how to make one:

I hope you are able to take her to the vet very soon. As Minnesota Zoo said, there are more vets now that take credit care.
Also, I know it is hard, but try not to be angry with your boys. It is just their instinct, and there are always risks with introductions.
I just hope everything will be fine with your babies.
Best of lucks
