Vitiligo of upper eyelid or periocular area – http://id.who.int/icd/entity/2122202235

This is a condition of the upper eyelid and periocular area that causes depigmentation of sections of skin. It occurs when melanocytes, the cells responsible for skin pigmentation, die or are unable to function. The cause of vitiligo is unknown, but research suggests that it may arise from autoimmune, genetic, oxidative stress, neural, or viral causes.
