The eye can be analyzed with relative ease regarding both its function and its structure. A practical evaluation consists of the ability to move in the orbit and the reaction of the pupil to light and accommodation.
The function of the eye might be checked in a number of methods. The patient might be asked to determine illuminated letter or objects of varying sizes on exactly what is called the Snellen chart.
Conversely, the assessment of the structural part of the eye may be made in a number of methods. Stress within the eyeball is determined by a "tonometer." In certain illness, specifically in glaucoma, the tension in the eyeball is increased markedly.
However, it needs to be well bore in mind that a patient with an eye problem may have other problems too. Often other physical conditions are primary and impact the eye as a effect.
