The eye can be examined with relative ease as to both its function and its structure. A functional evaluation includes the ability to move in the orbit and the response of the student to light and accommodation.
The function of the eye might be tested in a number of methods. The client might be asked to recognize illuminated letter or objects of differing sizes on exactly what is understood as the Snellen chart.
Alternatively, the assessment of the structural part of the eye may be made in numerous ways. Tension within the eyeball is determined by a "tonometer." In specific illness, particularly in glaucoma, the stress in the eyeball is increased significantly.
It ought to be well kept in mind that a patient with an eye problem may have other issues. Frequently other physical conditions are primary and impact the eye as a repercussion.
