Non-invasive assessment of corneal crosslinking changes using polarization sensitive optical coherence tomography

, 2013
Collagen crosslinking (CXL) has shown promising results in the prevention of the progression of keratoconus and corneal ectasia. However, techniques for in vivo and in situ assessment of the treatment are limited. In this study, ex vivo porcine eyes were

Electron Tomography of Corneal Collagen Fibrils

Microscopy and Microanalysis, 2001
Abstract The ability of cornea to transmit light whilst being mechanically resilient is directly attributable to the formation of an extracellular matrix containing orthogonally arranged sheets of densely packed uniformly-narrow collagen fibrils, in which each sheet contains parallel arrays of fibrils.
