On the other hand, the examination of the structural part of the eye may be made in several ways. Tension within the eyeball is determined by a "tonometer." In certain diseases, especially in glaucoma, the tension in the eyeball is increased considerably.
It ought to be well kept in mind that a client with an eye issue might have other issues. Frequently other physical conditions are primary and affect the eye as a consequence. The appearance of the eye can inform the client and the doctor to difficulties in some disturbances of other parts of the body even before other signs provide themselves.
