Spatial patterns and age-related changes of the collagen crimp in the human cornea and sclera
Purpose: Collagen is the main load-bearing component of the eye, and collagen crimp is a
critical determinant of tissue mechanical behavior. We test the hypothesis that collagen …

Collagen fiber recruitment: a microstructural basis for the nonlinear response of the posterior pole of the eye to increases in intraocular pressure
Our goal was to quantify and characterize how the collagen fiber crimp waviness of the
lamina cribrosa (LC) and peripapillary sclera (PPS) changes with intraocular pressure (IOP) …
