The eye can be taken a look at 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 pupil to light and lodging.
The function of the eye may be checked in a number of methods. The patient might be asked to determine illuminated letter or objects of differing sizes on exactly what is called the Snellen chart.
Conversely, the assessment of the structural part of the eye may be made in several ways. Stress within the eyeball is determined by a "tonometer." In certain diseases, particularly in glaucoma, the stress in the eyeball is increased significantly.
