With a PWS it is often good to consider treatment early. Here is some info from Dr. Nelson one of the leading laser expert and researcher. there is a widely cited Dutch study that did NOT show
any improved outcome was obtained with early therapy.
With that said, there are a number of good reasons from an optical
point of view to intervene earlier: 1) less epidermal melanin to
block the laser light; 2) less dermal collagen means less optical
scattering making laser treatment more effective; 3) blood vessels
size is smaller; and
4) lesion thickness is less.
Can a PWS completely be removed? Well, this is debated among specialists. At the vbf conference, Dr. Waner mentioned this questions. Because this is a capillary malformation, the is the chance that the pws will refill after treatments. PWS vary, so it is hard to predict which lesions will require many tx., to maintain fading and which lesions will be completely be faded long term. We have members that have to have annual tx., once they've reached the max. fading to maintain that fading. And we've also heard from patients that had multiple tx. and have not had to have any touch up work in many years.
I would encourage you to email Dr. Nelson on ask the expert page and provide a photo. He might be able to give you more specific answer in relationship to your child. It is best to see the specialist in person, but this is a starting point.
Also, what is the pattern of your son's birthmark? Is it near the eye, above and below the eye? It is important to have some things monitored/evaluated beyond tx. with laser.
Good luck and congratulations on your son!
