Fig. 7

Representative optical coherence tomography (OCT) image of each group (a) and corresponding tomographic distribution of attenuation coefficient of strain rate (ACSR) in the same sample (b). The yellow box is the measurement range of stress relaxation optical coherence straingraphy (SR-OCSA) and the red dotted line is the tidemark. Each group showed elevation of the ACSR around tidemark and the degree of elevation in the ACSR increased in a time-dependent manner
