The eye can be analyzed with relative ease as to both its function and its structure. A functional assessment includes the ability to relocate the orbit and the response of the student to light and accommodation.
The function of the eye may be checked in several ways. The patient may be asked to recognize illuminated letter or things of differing sizes on exactly what is called the Snellen chart.
On the other hand, the assessment of the structural part of the eye may be made in several ways. Tension within the eyeball is measured by a "tonometer." In specific diseases, especially in glaucoma, the tension in the eyeball is increased significantly.
Nevertheless, it must be well bore in mind that a patient with an eye issue might have other problems as well. Often other physical conditions are primary and impact the eye as a effect.
