Morphological studies of the cadaveric sclera after nonpenetrating sclerotomy by ND: YAG laser
Российский офтальмологический журнал, 2018 Purpose: to reveal the changes of the morphological structure of cadaveric human sclera after Nd: YAG laser irradiation.Material and methods. Laser pulses (Nd: YAG) (Lumenis) (power 7.0–7.4 mW, pulse duration 4 ns, wavelength 1064 nm) were applied to the

Collagen fiber interweaving is central to sclera stiffness
Acta Biomaterialia, 2020 The mechanical properties of the microstructural components of sclera are central to eye physiology and pathology. Because these parameters are extremely difficult to measure directly, they are often estimated using inverse-modeling matching deformations

Factors Governing Photodynamic Cross-Linking of Ocular Coat [PDF]
, 2011 This thesis addresses the challenge of minimizing toxicity of therapeutic protein-protein cross-linking of the cornea and sclera. Protein-protein cross-links include disulfide bonds, enzymatic cross-links and non-enzymatic cross-links.

Biomechanical properties of the rat sclera obtained with inverse finite element modeling
Biomechanics and Modeling in Mechanobiology, 2020 It is widely accepted that biomechanics plays an important role in glaucoma pathophysiology, but the mechanisms involved are largely unknown. Rats are a common animal model of glaucoma, and finite element models are being developed to provide much-needed

A Convolution Neural Network Engine for Sclera Recognition
Int. J. Interact. Multim. Artif. Intell., 2020 The world is shifting to the digital era in an enormous pace. This rise in the digital technology has created plenty of applications in the digital space, which demands a secured environment for transacting and authenticating the genuineness of end users.
