The eye can be analyzed with relative ease as to both its function and its structure. A functional examination consists of 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 ways. The patient may be asked to recognize illuminated letter or items of differing sizes on exactly what is called the Snellen chart.
Conversely, the assessment of the structural part of the eye might be made in numerous methods. Stress within the eyeball is determined by a "tonometer." In certain diseases, specifically in glaucoma, the stress in the eyeball is increased markedly.
