Did you look at the picture of your son with the big white spot on his eye that shows up on that picture? I don't want to freak you out but read the second clicky I remember not to long ago getting a e-mail regarding this. I truly hope it is nothing but I would get it checked out.

Parents should look out for a white pupil in the middle of the eye that is picked up with reflection from a flash that is not normal.
"Having said that, not all white reflections are caused by retinoblastoma, but you have to rule it out."

Oops, I misread your OP. I don't know what to think or say. You'd think with all the hundreds of pics I take of him, that would have happened once before. I need to give this some thought. Thanks for pointing it out.
