The eye can be taken a look at with relative ease as to both its function and its structure. A practical examination includes the ability to move in the orbit and the response of the pupil to light and lodging.
The function of the eye might be evaluated in several ways. The client might be asked to determine illuminated letter or things of differing sizes on what is called the Snellen chart.
On the other hand, 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 certain illness, particularly in glaucoma, the stress in the eyeball is increased noticeably.
However, it should be well bore in mind that a patient with an eye problem might have other problems as well. Frequently other physical conditions are primary and affect the eye as a consequence.
