Vitiligo Calculator for iOS

This App includes the calculator of the Vitiligo Extent Score (VES). The VES is a measure to express

the overall vitiligo involvement of the body (extent). It is designed for physicians to support the

assessment of the vitiligo extent. It can be used in clinical trials and daily practice. With this App the

total extent score or the extent score per body part can be calculated. The calculation can also be

summarised in a PDF file. This file can be sent to you email address. Construction was performed at

the Ghent University Hospital/Ghent University by Prof. N van Geel and Prof. R. Speeckaert

(copyright). The vitiligo extent score was validated (paper version) in cooperation with the

International vitiligo score working group.

Visit https://www.vitiligo-calculator.com to find out more about the VES. A blank version of the VES

tool to print can be downloaded by this website. This printed template can be used to mark the

vitiligo extent and to calculate the score later.

This calculator includes pictures that reflect vitiligo lesions of different degrees of extent. For each

area one picture can be selected, which best represents the extent of the vitiligo lesions. In order to

ensure a more accurate calculation, each picture gives you several sub-options that can be selected if

necessary.

After choosing a picture (or a second option if needed), the score [i.e. percentage of body surface

area (BSA) involved] will be automatically calculated. If no picture or second option is selected, this

will automatically result in 0% of body surface area involved.
