Comparison of two methods for evaluation of underneath eye wrinkles / 中华医学美学美容杂志

ABSTRACT

Objective To investigate the applicability of clinical grade and a non-contact measurement method in evaluation of underneath eye wrinkles and to compare two methods.Methods A lot of 46 healthy Chinese women were recruited for this study.Underneath eye wrinkles severity was evaluated using clinical grade and a non-contact measurement method.The correlations were calculated for clinical grade and non-contact measurement parameters and age.The non-contact measurement parameters were classified by factor analysis.The correlations between age,clinical grade and factors were analyzed.Results The correlation coefficient between clinical grade in comparison to subject's age was 0.818.The parameters getting from non contact measurement were obviously correlated with age and clinical grade except SEr and SEsc;the correlation coefficients between parameters and age were-0.601 to 0.605;the correlation cofficients between parameters and clinical grade were-0.630 to 0.570.The non-contact measurement parameters could be classified into two factors;one represented wrinkle depth and roughness;the other represented wrinkle width and counts.These two factors were also obviously correlated with age and clinical grade.Conclusions Clinical grade and non contact measurement methods are both applicable in evaluation of underneath eye wrinkles.The parameters getting from two methods are obviously correlated with each other.
