Ocular pharmacokinetic assessments pose challenges in the study design due to the inherent variability associated with nonserial sampling and the technical hurdles associated with developing sensitive bioanalytical methods in multiple matrices. Module 2 is ocular Anatomy. The iris a muscle is the colored part of the eye that contracts and expands to let light into the eye.

The globe is composed of three basic layers or coats. The strongest attachment is at the ora serrata. The orbit is the bony eye socket of the skull.
