The VES (Vitiligo Extent Score) is a measure to express the overall vitiligo involvement of the body
(extent).
This calculator (including VES, SAVES, VESplus and VSAS) is intended for use by physicians in clinical trials and daily practice for the assessment of vitiligo.
The pictures that reflect the extent of the vitiligo lesions can be selected by this tool. The calculator provides a score that can be expressed in percentage of the body surface area (BSA) involvement or grade of extent per region (Grade 0 tot 6).
The video below includes an explanation of the VES, VESplus and SAVES, as well as instructions on how to utilize these scores.
