Uh oh, another surgery So…last week, Tofu’s corneal ulcer went from completely healed to a brand new corneal ulcer followed by a very bad infection. A corneal ulcer is just a fancy word for a scratch on the surface of the eye. With a blind eye that is constantly open, it is prone to things poking in there and scratching the surface which can quickly lead to infection. By quickly, I mean quickly! On Thursday it was decided by the vet he must have his eye removed (enucleation).
