On the other hand, the evaluation of the structural part of the eye may be made in numerous ways. Stress within the eyeball is measured by a "tonometer." In specific diseases, specifically in glaucoma, the tension in the eyeball is increased significantly.
It needs to be well remembered that a client with an eye problem might have other issues. Typically other physical conditions are primary and affect the eye as a consequence.
