On the other hand, the assessment of the structural part of the eye might be made in several methods. Tension within the eyeball is determined by a "tonometer." In specific illness, specifically in glaucoma, the stress in the eyeball is increased significantly.
Nevertheless, it ought to be well kept in mind that a patient with an eye problem may have other problems also. Often other physical conditions are main and affect the eye as a consequence.
