Ruptured eye??

My rat Jitters is a year old double rex.. I've been traveling on business for the last month roughly.. any way, my husband was watching my rats. She shares a large cage with 4 other sisters. She was getting her eyes wiped out regularly but since I've been gone.. I don't think it's been happening sadly. I noticed blood around her eye when I went to get her out.. and I freaked. She had a small bubble on the surface of her eye.. it seems to have popped since she was rubbing her face against my shirt. What happened ?? Can someone else please help me? I can't call a vet until tomorrow morning as it's 641pm.

How is she doing? Were you able to get to the vet?

Luckily yes... she has a deep cornea scratch.. most likely won't be able to use it due to scaring.. hopefully it doesn't have to be removed. She is separated from her sisters and is on metacam as well as antibiotic ointment for the eye. Thanks for asking...
