Glaucoma may be best performed at the beginning of the disease by the amount of damage to the optic nerve. Therefore, damage glaucomatous optic nerve at this level without losing the visual field is usually regarded as the beginning of glaucoma. Visual field Test to measure all areas of Your vision, Your vision including peripheral or side. Although perimetry is the gold standard for diagnosing glaucoma, it has its limitations as a screening test. It's expensive, time consuming and technically complicated. Also, perimetry to detect patients with late in the course of glaucoma. One method involved the staging of the disease by how much loss of vision in the visual field test to staging may underestimate the severity of the damage, as fixed the normal visual field until there is substantial damage to the optic nerve.
Vision loss from glaucoma irreversibly unfortunately. However, it is very important to keep a regular complete eye care. It may be that the glasses, cataract surgery, and the treatment for diabetic macular edema or hemorrhage may be required which can improve vision. This test requires you to see straight ahead and indicate whether You see the lights blink on and off in different locations in Your peripheral vision. Learning effects involved by taking this test, and physicians may choose to repeat it at regular intervals. Perimetry tests can help find certain patterns of loss of vision. This may mean there are certain types of eye diseases. This is very useful in finding the beginning of a change in vision caused by nerve damage from glaucoma.Routine tests can be used in perimetry to see if treatment for glaucoma is to prevent loss of vision.
Thyroid function is high and low has been implicated as a risk factor for glaucoma, although evidence from epidemiological studies that were not consistent. In these conditions, eye movements of the muscles are tight or confined to the eye can cause an increase in pressure of the eye which is generally temporary but can in some cases lead to damage to the optic nerve. Some studies have involved hypothyroidism as a risk factor for glaucoma, hypothyroidism can cause an abnormal accumulation of substances in the drainage system in the eye, leading to increased pressure of the eye, a known risk factor for the development of glaucoma. Ongoing research will help to better define the role of thyroid disease in glaucoma and increase our understanding of the mechanisms involved.
