The manner in which the eye responds to chemicals, radiation, and other toxic insults is influenced by many factors, some of which are described elsewhere in this book. Variations in morphology, physiology, biochemistry, and pharmacology of the eye in different species of animal may have a significant effect on the reaction of the eye to injury or toxins. Even within a particular species, difference in age and degree of ocular pigmentation may affect the eye’s response to, and recovery or repair from, noxious substances. The area of the eye in which most differences are seen and about which most is known is the anterior uvea and the response of the iris sphincter muscle and blood-aqueous barrier to toxic substances. For this reason, the anterior uvea will receive most attention.
