My response may seem kind of like a non-response - but here goes:
I'd suggest talking to the bride and groom about it. Find out how they want it shown / handled. Certainly they are aware of the condition and will probably have ideas on how they want it handled.
My guess is that they would consider it like any other physical feature and not want anything special or different done to cover, hide or change it. And unless they specifically ask for something - I would not just assume that they want it minimized, covered or hidden.
