Figure 2. Effects of CDECM on the corneal surface irregularities. A: The eyes of the PBS and chondrocyte-derived extracellular matrix (CDECM) groups were imaged using a microscope after the removal of desiccation stress (DS). PBS or CDECM was instilled five times per day for the indicated number of days, and the corneal smoothness of the NOD.B10.H2^b mice was measured 3, 5, 7, and 10 days of instillation. Scale bar=1 mm. B: Changes in the corneal irregularity scores in the experimental NOD.B10.H2^b mice after the removal of DS in the PBS and CDECM groups. The quantitative data are presented as mean ± standard deviation (SD). *p<0.05 versus the value in the PBS group. #p<0.05 versus the corresponding value in the DS 10 day (10D) group.
