Shear Wave Optical Coherence Elastography and Structural Analysis of the Postnatal Mouse Cornea Through Development.
The cornea is a transparent lens at the forefront of the eye, serving as a structural barrier that protects the eye and provides the majority of the eye's refractive power. In this study, we utilized the postnatal mouse eye to characterize corneal structure and biomechanics. Between postnatal day (PN) 6 and PN24, we observed that elastic wave speeds are highest at PN6, gradually decrease through PN24, and then start to rise in adulthood (6 months). We found that corneal thickness is uncoupled from elastic wave speed and that the content and organization of the cornea primarily influence its mechanical properties. To the best of our knowledge, this work is the first detailed assessment of the postnatal mouse cornea's structure and biomechanics and warrants further investigation into the dynamic properties of the postnatal eye.
