The eye can be examined with relative ease as to both its function and its structure. A functional examination consists of the capability to move in the orbit and the response of the student to light and lodging.
The function of the eye may be checked in a number of ways. The patient might be asked to identify illuminated letter or things of differing sizes on exactly what is referred to as the Snellen chart.
On the other hand, the examination of the structural part of the eye may be made in numerous methods. Stress within the eyeball is measured by a "tonometer." In specific illness, specifically in glaucoma, the tension in the eyeball is increased markedly.
However, it should be well kept in mind that a patient with an eye problem might have other problems as well. Often other physical conditions are primary and affect the eye as a repercussion.
