ABSTRACT

Exposure to many substances can disrupt the delicate ocular tissues, with the cornea being most likely to be affected by topical exposures and the visceral tunic and retina primarily affected by systemic agents. The ocular tissues detailed herein are those that generally demonstrate toxicological effects resulting from either topical

exposure or systemic administration of various substances. The descriptions provided in the following sections are for the human eye, unless otherwise noted. Figures 4.1 through 4.3 show anatomical structures of the human eye in sagittal section, whereas Figures 4.4 and 4.5 respectively depict the basic structures of the rabbit eye and cornea in sagittal section.
