To establish a visual assessment scale for the severity of dark circles' pigmented and vascular type in Chinese women.
A total of 269 healthy Chinese women from Shanghai with different degrees of dark circles', both pigmented and vascular types, were evaluated by visual assessment. Photographs of their dark circles were analyzed by image analysis.
The visual assessment evaluation on classification and severity showed a favorable agreement between the successive measured results. Significant differences from very slight to severe dark circles for pigmented type and vascular type were observed. The severity level by visual assessment was significantly positively correlated with ΔE values while negatively correlated with ΔL values (P < .01) in both pigmented and vascular types. Besides, Δa values of vascular type were significantly positively correlated with the ΔE values for dark circles' vascular type. Values between ΔE and ΔL also showed a significant negative correlation (P < .01).
The five-point visual assessment scale for dark circles of vascular and pigmented types was verified and proved to have good repeatability. The image analysis's objective result proved significant and consistent with the visual assessment and color parameters. This scale could be a useful and effective tool in diagnosing dark circles' severity.
建立中国女性色素型和血管型黑眼圈严重程度的视觉评估量表。
对来自上海的 269 名不同程度色素型和血管型黑眼圈的健康中国女性进行视觉评估。对其黑眼圈的照片进行图像分析。
分类和严重程度的视觉评估评估结果在连续测量结果之间具有良好的一致性。观察到色素型和血管型黑眼圈从非常轻微到严重的严重程度差异显著。视觉评估的严重程度水平与 ΔE 值呈显著正相关，与 ΔL 值呈显著负相关（P<.01），在色素型和血管型中均如此。此外，血管型的 Δa 值与血管型黑眼圈的 ΔE 值呈显著正相关。ΔE 和 ΔL 之间的值也呈显著负相关（P<.01）。
验证并证明了血管型和色素型黑眼圈的 5 点视觉评估量表具有良好的可重复性。图像分析的客观结果与视觉评估和颜色参数具有显著的一致性。该量表可能是诊断黑眼圈严重程度的有用且有效的工具。
