Abstract

This chapter focuses on the child with sensory alteration. This chapter covers the eye and disorders of the eye, refractive errors, and ear and disorders of the ear. The eyes are the sense organs for vision. The orbit of the eye is a bony cavity that contains the eyeball, muscles, nerves, and blood vessels, as well as the structures that produce and drain tears. Sclera is the white layer, which covers the eyeball. The eyes are complex organs, with many parts that must work together to produce clear vision. Eye development continues until a child is six years old. Blindness is defined as the state of being sightless, which spans a range from total blindness to 20/200 vision in the better eye with best correction.
