Screening neonatal jaundice based on the sclera color of the eye using digital photography

Terence S. Leung, Karan Kapur, Ashley Guilliam, Jade Okell, Bee Lim, Lindsay W. MacDonald, Judith Meek
2015 Biomedical Optics Express  
It involves taking digital photographs of newborn infants' eyes (n = 110) and processing the pixel colour values of the sclera to predict the total serum bilirubin (TSB) levels.  ...  A new screening technique for neonatal jaundice is proposed exploiting the yellow discoloration in the sclera.  ...  However, the white balancing is normally used to reduce the effect of colour differences under different illuminations.  ...

Bailey G. Hannon, Stephen A. Schwaner, Elizabeth M. Boazak, Brandon G. Gerberich, Erin J. Winger, Mark R. Prausnitz, C. Ross Ethier
2019 Journal of the Royal Society Interface  
We assessed first principal Lagrange strain of the posterior sclera using digital image correlation as a proxy for scleral stiffness.  ...  We conclude that a single in vivo injection of genipin effectively stiffened rat sclera for at least four weeks which motivates further functional studies and possible clinical translation of genipin-induced  ...  Sherwood for help with the iPerfusion software used for the inflation tests.  ...
