Poor Munchkin! It's quite serious that she cannot open her eye all the way. Without seeing her in person, I can't rule out an injury to it or an eye infection, but I can say she needs to see a vet immediately. The eye is such a delicate and important structure that any problem with it should be considered an emergency. That's because leaving it untreated can lead to vision loss. I would take Munchin into an ER vet or find a vet on call to see her now to have her eye examined and diagnosed so it can be treated.
