Oh, that's so sad! I think you should try the antibiotics first, to try to save any possible hope for any sight she might have left, even if it is only light perception. IF that doesn't work, you will know you tried, and then you can then decide whether or not it would be in her best interest to have the eyes surgically removed, etc.

I will keep her in my prayers, and YOU as well. I know how difficult this must be on you. But go with what your conscience tells you needs to be done, and you won't go wrong. No matter what happens, you will be OK, and she will be OK. Just take things one moment, one day at a time for now, and you will both get through it.

Again, you will be in my thoughts and prayers....
