I had a turtle a few years ago and she got sick. Her eyes looked EXACTLY like that. My father took her to a vet and since I wasn't there I don't know all that the vet said, but I do know for sure that he gave her a shot. I am guessing it is an infection and the shot maybe was some sort of antibiotic. You do need to take her in though; she will not get better on her own. You are probably having a hard time getting her to eat too just because she can't see. I used tweezers to hold the food close to her mouth (she was a baby).
