If vitiligo photos are taken differently at each clinic, wouldn't comparison be difficult?
Standardizing serial photography for assessing and monitoring vitiligo: A core set of international recommendations for essential clinical and technical specifications.
Final review
In short
Vitiligo experts from around the world gathered to establish a standard method for taking photos, ensuring they can be compared regardless of when or where they are taken.
Sometimes, even when the same area is photographed, the color looks different from the previous photo. This is because the lighting, angle, or background has changed slightly. When this happens, it is difficult to determine whether the condition has improved or worsened. The problem becomes even greater if each clinic uses a different photography method. Therefore, I addressed this issue together with vitiligo experts from around the world. This is a study that established international standards for photography so that photos can be compared regardless of when or where they are taken.
Q1 Why should the way photographs are taken be standardized?
Because if the photos are inconsistent, it is impossible to accurately assess treatment progress. Vitiligo requires comparing changes over a long period through photographs. However, if the shooting conditions vary each time, an improvement may appear as a worsening, and conversely, a worsening may appear as an improvement. By standardizing the photography method, comparisons can be made using the same standard even over time or at different clinics. This is especially important in clinical care and in research involving multiple clinics.
Q2 What recommendations were made?
The recommendations divide the essential photo sets into clinical and research uses. For clinical care, 10 photos are the standard; for research, 15 photos. The photographed areas follow the body regions used in the vitiligo extent score. In addition, posture, background color, lighting, location markers, and size reference were standardized. It is recommended to take both regular photos and photos taken with a Wood's lamp (ultraviolet light) together. This result was refined through repeated review until a consensus was reached among 20 vitiligo experts worldwide.
Summary of Standard Photography Recommendations
| Item | Content |
|---|---|
| Clinical use | Standard set of 10 photos |
| Research use | Standard set of 15 photos |
| Photography reference | Body regions used in the vitiligo extent score |
| Standardized items | Posture, background color, lighting, location markers, size reference, regular photos and Wood's lamp photos |
Closing remarks
Thanks to this recommendation, vitiligo photos have become data that can be compared no matter who takes them. Research from different countries can now be aligned, and in the clinic, we can show patients how their condition has changed since the last visit using the same standard. Although it may seem like a minor photography rule, it serves as the foundation for fairly evaluating treatment effects.
