Good news -- Sweet Pea had an appointment with her ophthalmologist yesterday, and he confirmed that her vision is no longer affected by her hemangioma. It has flattened a bit since she started taking Propranalol, although it is still pretty dark and just as wide.
Hopefully the color and size will start reducing soon. But for now, I am thrilled that we don't have to worry about her eyesight. Woo hoo!
