This presentation describes the unique anatomy and physiology of the vascular beds that serve the eye. The needs for an unobstructed light path from the cornea to the retina and a relatively fixed corneal curvature and distance between refractive structures pose significant challenges for the vasculature to provide nutrients and remove metabolic waste. To meet these needs, the ocular vascular beds are confined to the periphery of the posterior two thirds of the eye and a surrogate circulation provides a continuous flow of aqueous humor to nourish the avascular cornea, lens and vitreous compartment. The production of aqueous humor (and its ease of egress from the eye) also generates the intraocular pressure (IOP), which maintains the shape of the eye. However, the IOP also exerts a compressing force on the ocular blood vessels that is higher than elsewhere in the body. This is particularly true for the intraocular veins, which must have a pressure higher than IOP to remain patent, and so the IOP is the effective venous pressure for the intraocular vascular beds. Consequently, the ocular circulation operates at a lower perfusion pressure gradient than elsewhere in the body and is more at risk for ischemic damage when faced with low arterial pressure, particularly if IOP is elevated. This risk and the specialized tissues of the eye give rise to the fascinating physiology of the ocular circulations.

This book covers sports-related eye injuries, presenting standard processes to enable clinical practitioners to make appropriate decisions on the management of these patients. Sports-related activities are responsible for a large percentage of ocular injuries, particularly among young people, and can even lead to blindness. Given the increasing trend in these injuries and the potential functional loss they entail, it is important to understand how to prevent and to accurately diagnose and treat them. This book discusses the definition, etiology, clinical presentations and signs, treatment, and prevention of sports-related eye injuries, and includes typical clinical cases, together with a wealth of images and illustrative figures. Offering a systematic and symptom-based guide to clinical practice, it will help clinical practitioners to fully prepare for the various challenges posed by sports-related eye injuries.

Since ocular infections are one of the most frequent occurrences in ophthalmology, the treatment for these infections must be fast, precise and effective. In order to address this goal, it is important to identify and characterize the culprit microorganisms involved in the pathogenesis of ocular infections. Clinical diagnosis of ocular infections can be confirmed by several techniques based on microbiological test of ocular samples. Some of these techniques include classic microbiological testing in which it is necessary to isolate microorganisms to characterize them by biochemical analysis which require significant resources and timing.
