The eye can be analyzed with relative ease as to both its function and its structure. A practical examination includes the ability to relocate the orbit and the reaction of the pupil to light and accommodation.
The function of the eye might be checked in several ways. The patient may be asked to determine illuminated letter or items of varying sizes on exactly what is called the Snellen chart.
Conversely, the evaluation of the structural part of the eye might be made in several ways. Stress within the eyeball is determined by a "tonometer." In certain diseases, particularly in glaucoma, the stress in the eyeball is increased considerably.
It must be well remembered that a client with an eye issue might have other issues. Typically other physical conditions are primary and affect the eye as a effect.
