The eye can be examined with relative ease as to both its function and its structure. A practical assessment includes the capability to relocate the orbit and the response of the student to light and lodging.
The function of the eye may be checked in a number of methods. The patient might be asked to recognize illuminated letter or items of differing sizes on what is called the Snellen chart.
Conversely, the evaluation of the structural part of the eye might be made in numerous methods. Tension within the eyeball is measured by a "tonometer." In particular illness, particularly in glaucoma, the tension in the eyeball is increased noticeably.
However, it must be well bore in mind that a patient with an eye issue may have other problems as well. Typically other physical conditions are primary and impact the eye as a consequence. The appearance of the eye can signal the physician and the patient to difficulties in some disturbances of other parts of the body even before other signs provide themselves.
