On the other hand, the examination of the structural part of the eye might be made in several ways. Tension within the eyeball is measured by a "tonometer." In particular diseases, specifically in glaucoma, the tension in the eyeball is increased markedly.
It ought to be well kept in mind that a patient with an eye problem might have other problems. Frequently other physical conditions are main and impact the eye as a repercussion. The appearance of the eye can inform the doctor and the patient to problems in some disturbances of other parts of the body even before other symptoms provide themselves.
