The eye can be examined with relative ease regarding both its function and its structure. A practical assessment consists of the capability to move in the orbit and the reaction of the student to light and lodging.
The function of the eye may be tested in several methods. The patient may be asked to recognize illuminated letter or objects of differing sizes on what is known as the Snellen chart.
Conversely, the assessment of the structural part of the eye may be made in several methods. Tension within the eyeball is determined by a "tonometer." In certain illness, particularly in glaucoma, the tension in the eyeball is increased markedly.
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.
