Any ideas, my 3yr old dd had earlier and yesterday been rubbing her eye a bit and today every few hours a very small amount of yellow gunk appeared in the corner. She says it doesn't hurt or bother her but that there's a stone in her eye (!). Taking her to bed I noticed a white spot on her eyeball next to the iris about the size of a small pea. Am phoning the dr in the morning for myself so was going to ask about this but I'm just curious if anyone else has seen it, not much on google
