I have a 9.5 year old who was diagnosed with CM/SM and treated with surgery at about 4 years old. Lately we have noticed that his third eyelid protrudes further than usual. It comes and goes throughout the day. It doesn't really seem inflamed (red) and we keep thinking it's allergies, but because it comes and goes all day I'm wondering if it may be related to the SM. Has anyone else expreienced eye issues related to SM? Thanks!
