LAS - glad you found the MSN site - people on there are fantastic.
In short the UK policy is to wait until the child is older before operating, if we had done that my son would have lost his eyesight and usffered permanent scarring, and that was following constant referrals to every birthmark specialist in the UK, including GOSH. I'm not a fan of the NHS attitude to hemangiomas(as far as my DS1 is concerned), though I know a few people who have had good experiences.
Having stumbled across the MSN site I found Dr Milton Waner and Dr Aaron Fay, US facial reconstruction surgeon and occular surgeon, 2 world renowned experts. Dr waner works solely with patients with extensive birthmarks. There are no other surgeons in Europe with the experience or expertise that he shares with a few US colleagues.
My son has reconstructive surgery - plastic surgery basically, no expansion, but lots of lifting and re-positioning. Much of what they have worked on has been beneath the surface of the eye, plus some laser treatment which has significantly accelerated the lightening of the mark.
I hope that's helpful, please ask if there is anything at all I can help with.
