Tania Martín-Pérez, Ángel Criado-Fornelio, Manuel Ávila-Blanco, and Jorge Pérez-Serrano begin this book by reviewing studies that propose species identification should be established on complete gene sequence rather than small fragments that might be unreliable. Afterwards, Eva García Millán, Ana Castro-Balado, Anxo Fernández-Ferreiro, and Francisco J. Otero-Espinar suggest that soft contact lenses have potential to be used as drug delivery systems by way of a medicated lens. Next, Maria J Giraldez, Ph.D., Carlos Garcia-Resua, Ph.D., and Eva Yebra-Pimentel, Ph.D. examine the properties of contact lenses in order to determine a means of reducing microbial contamination. Pablo J Franco, Pablo H Sande, Florencia González Fleitas, Julián D Devouassoux, Georgia Milnes, Hernán H Dieguez, Marcos L Aranda, Damián Dorfman, and Ruth E. Rosenstein present research that shows biologic treatments could be used in uveitis treatment. Following this, Rodrigo Mora-Martínez and Ernesto Suaste-Gómez, Ph.D. explore the impact of chromatic stimuli on various pupillary phenomena to reveal divergences between separate chromaticities. Frederick R Burgess and Roly Megaw provide an overview of the known literature on mesenchymal stem cells physiology. Then, David Lozano Giral, MD, Enrique Graue-Hernández, MD, and Alejandro Navas MD, Ph.D. review the cornea and its properties. Sivan M Elyashiv and Richard B Rosencompare in face OCT images with OCT angiograms in an effort to identify the level of capillary dropout, remodelling, and the development of neo-vascularisation.
