The eye can be analyzed with relative ease as to both its function and its structure. A functional evaluation consists of the ability to relocate the orbit and the response of the pupil to light and lodging.
The function of the eye might be tested in a number of methods. The patient may be asked to identify illuminated letter or items of differing sizes on exactly what is known as the Snellen chart.
Conversely, the evaluation of the structural part of the eye might be made in a number of ways. Stress within the eyeball is measured by a "tonometer." In specific diseases, particularly in glaucoma, the stress in the eyeball is increased markedly.
However, it should be well kept in mind that a patient with an eye problem may have other issues too. Frequently other physical conditions are main and impact the eye as a effect.
