Before we get treatments for vitiligo, we’d better to figure out the stage of vitiligo. The active stage vitiligo is with great risk to spread to other areas. 2011 international Melanin Cell Convention European Academy Judgment Standard for Vitiligo Stage.
It takes pictures to compare the previous 12 months white spots area changes. And based on the patients review and clinic score system (VASI or VETF) to test the individual stability.
(1) The judgment standard refers to vitiligo disease activity score (VIDA): the recent 6 weeks occur new skin lesions or the previous skin lesions enlarged (+4 points); the recent 3 months occur new skin lesions or the previous skin spots enlarged (+3 points); the recent 6 weeks occur new skin lesions or the previous skin spots enlarged (+2 points); the recent 1 year occur new skin lesions or the previous skin spots enlarged (+1 point); at least one year show stable condition (+0 point); at least one year show stable condition and have new pigment (-1point). The total score is less or equal 1 point that is the stable stage, the score is more than 1 point is the active stage, while the score is more than 4 points that is the rapid developing stage.
(2) The judgment standard refers to Wood lamp: in the nature light to observe the skin lesion, then we need prepare it under the wood lamp. The active stage will show a bigger white area than the natural light. The stable stage shows an equal or less white area than the natural light.
(3) The other methods: the isomorphic effect shows that is in the active stage.
