I am so glad to hear that you have your children's vision checked.
Thanks for giving this post a bump.
This is something that can so easily be done at a minimal cost and can truly save a life. My son was diagnosed at two and a half months. Lucky for him the tumor was close enough to the center of the retina that I could see it. He had not had his eyes checked except at his regular two month check up which of course was without dilation.
