Today was a great day! The eye surgeon came in for Sam's first follow up exam and told us that everything looks really good. I think the direct quote was "I would be shocked if things took a turn for the worse". I am translating that to mean, Sam's retina is nicely attached and should stay that way. No blindness for our little man! There may be some vision issues, but some vision issues are way better than blindness!!!
Thank you to everyone for your support and concern. I think we can mark this off the list of things to worry about.
