Vitiligo affects about 1% of the world's population, however, there is currently no universally used standardized measure to assess its response to treatment.
To find the most effective technique for the quantitative assessment of therapeutic results in vitiligo patients.
The study was performed in three stages: (1) Conducting an adapted Delphi survey to check current dermatologists' attitudes regarding the topic of study. (2) Conducting a pilot study that involves testing the selected digital image analysis software in the laboratory to validate future tasks. (3) The chief clinimetric study that implicates selecting actual vitiligo lesion models and evaluating them.
Regarding the surface area measuring techniques, the most accurate results were gained through the digital image analysis for surface area, followed by point-counting technique. The digital image analysis for color measurement was accurate and reliable in getting a percentage representation of color improvement within the vitiligo lesions, in response to therapy.
Many dermatologists lack understanding of basic concepts about imaging techniques. The study does not include a traditional assessment method such as vitiligo area scoring index.
Our designated digital image analysis technique was able to efficiently assess the changes that occur both on surface area and the color of vitiligo lesions in response to therapy.
白癜风影响着全球约 1%的人口，然而，目前还没有普遍使用的标准化方法来评估其治疗反应。
寻找评估白癜风患者治疗效果的最有效技术。
该研究分三个阶段进行：（1）进行适应性 Delphi 调查，以检查皮肤科医生对研究主题的当前态度。（2）进行试点研究，在实验室中测试选定的数字图像分析软件，以验证未来的任务。（3）主要临床计量学研究，涉及选择实际的白癜风病变模型并进行评估。
在面积测量技术方面，数字图像分析的结果最为准确，其次是点数法。数字图像分析的颜色测量在获得治疗后白癜风病变颜色改善的百分比表示方面是准确可靠的。
许多皮肤科医生对成像技术的基本概念缺乏了解。该研究不包括白癜风面积评分指数等传统评估方法。
我们指定的数字图像分析技术能够有效地评估治疗后白癜风病变的面积和颜色变化。
