三种皱纹评价方法的比较

目的皱纹是皮肤老化的一种标志,探讨建立对皮肤皱纹评价的客观简易方法,为皮肤老化课题的进一步研究提供主客观的评价标准. 方法用临床主观评分、 Photoshop 7.0软件及Visioscan VC98软件3种方法对481名中国女性面部皱纹进行评估,通过主观评分将481张图像分为9个等级,再利用上述两种软件中的参数对9个等级的图像进行分析,统计出各个参数与主观评分的相关程度. 结果主观评分与Photoshop中的直方图中间值、Level值及SD值有较好的相关性,与Visioscan的质地参数和SELS参数也有较好的相关性.结论主观评分、Photoshop软件评价、Visioscan评价,这3种方法均能从一定程度上反映皮肤老化情况,且有各自的参数,可以根据具体实际情况和要求选择合适的方法及相关参数.

Comparison of three methods for evaluation of wrinkles

Objective Wriokle is the sign of skin aging. In order to provide a method for the further study of skin aging, we established some methods for the evaluation of wrinkles. Methods Three methods were used to evaluate wrinkles. 481 Chinese women with wrinkles on their faces were assessed and analyzed by clinical grading, Photoshop and Visionscan meter. We tried to check out the correlation between them. 481 pictures were divided into nine ranks. By using the softwares, we analyzed pictures again. And we calculated the correlation of all the parameters. Results There was good linear relationship between clinical grade and median, and also between values of LEVEL and SD by Photoshop histognam analysis. By Visionscan meter, there was good linear relationship between clinical grade and texture parameters, and also between SELS parameters. Conclusions All the three methods can reflect the skin aging in some degree. In clinical practice, different method or parameter will be chosen according to the different instance.
