Hello- I stumbled on this stream as I was researching information on Hemangioma's under the eyelid. My son who is almost 4 now has had a hemangioma under his eyelid since about 3 weeks of age. He currently wears glasses due to astygmatism from the birth mark, and we have to patch his "good" eye inorder to strengthen the eye with the hemangioma, as the tendency is to rely on the "stronger" eye, and the "weaker" one does not develop the vision. This birthmark has cause anxiety for us thoughout his life for us his parents, but has not caused much for him. If you want more info, or to chat, feel free to email me and I can answer any personal questions. This condition is an emotional challenge, but as long as is treated properly, is fairly cosmetic. I definitely recommend consultaition with an pediatric opthamologist, which it sounds like you may have. Like I said, we noticed the hemagioma about 3 weeks of age, I don't know how old your child is, but like the neo recommended, don't worry about it unless it starts obstructing the vision.
