I dont know much about it, other than having heard the name. I would say that it shouldnt cause a problem in real relationships. Its the traditional thing of if someone cares about you a problem like viltigo (sorry if its spelt wrong!) shouldnt bother them, they should love you for who you are. The only way it will affect relationships is if you are self-concious of it (dont be, youll still be the same brilliant person with or without it!) or if it spreads and becomes more noticeable where unfortunately you may have to learn to deal with people staring, and then youre partner would do as well.
