The eye can be analyzed with relative ease regarding both its function and its structure. A functional assessment consists of the ability to relocate the orbit and the reaction of the student to light and accommodation.
The function of the eye may be evaluated in several ways. The patient might be asked to recognize illuminated letter or items of differing sizes on what is referred to as the Snellen chart.
Conversely, the assessment of the structural part of the eye may be made in a number of methods. Stress within the eyeball is measured by a "tonometer." In certain illness, especially in glaucoma, the stress in the eyeball is increased markedly.
