The eye can be examined with relative ease as to both its function and its structure. A practical examination consists of the ability to move in the orbit and the response of the student to light and accommodation.
The function of the eye may be tested in numerous ways. The patient might be asked to recognize illuminated letter or objects of varying sizes on what is called the Snellen chart.
Alternatively, the examination of the structural part of the eye might be made in several ways. Stress within the eyeball is determined by a "tonometer." In specific diseases, particularly in glaucoma, the stress in the eyeball is increased markedly.
It should be well remembered that a client with an eye issue may have other problems. Often other physical conditions are primary and affect the eye as a effect. The look of the eye can notify the physician and the patient to troubles in some disturbances of other parts of the body even prior to other symptoms provide themselves.
