Hello, my ferret has a balance problem which the doctor couldn''t figure out, it seemed to correspond with an ear infection. But even after the infection she still prones to the right all the time. Just two days ago we noticed around her right eye was all swollen and red, so we put her in her bed and made her sleep lots over the last two days. At the time it seemed her right eye the actual eyeball was turning white, and now it is very white as if blind. Can you tell me what that is and if i need to take any immediate action.

Optional Information:
Age: 8; Female; Breed: ferret
