A lot of instances of degraded vision have been attributed to getting old, and many of these may be accurate. But your Flint optometrist can tell you that the bases why growing old can cause vision degradation has not been clarified much, so that is has turned to almost a catch-all phrase for numerous problems associated with it. However, medicine knows glaucoma as one of the causes for poor vision, so you can ask your optometrist in Flint for the indicators of glaucoma.

How glaucoma develops

Glaucoma are those kinds of eye diseases that progressively damage the optic nerves, changing the optic nerve head and the retina. Two theories have been advanced as to its cause: (1) the ‘mechanical’ theory which states that the inordinate pressure of the aqueous humor causes injury to the fibers of the optic nerve, while the (2) ‘vascular’ theory insists that optic degradation is due to nerves wasting from lack of nourishment. A new third theory postulates that changes in the internal pressures of the eye orb injure the retinal and optic construction so that they turn to be more easily damaged. However, this third theory is up to now under detailed study.

Glaucoma determination tests]

supposed, three tests are made to reveal its incidence. The first is optic disc assessment, which measures the optic discs according to a series of averages, so that variation from normal may be owed to the disease. The second, is a visual field assessment, calculates how the eye sees the variation between a background color and the color of the object in the foreground. There are several categories of eye defects listed under this method, correlated generally with [damage|injury} to the retina. Visual field assessment tests are normally performed againwhen glaucoma is detected, just for precisionof prognosis.

The third way is IOP test that assesses the intraocular pressure inside the eyeball. This appears to be the least reliable among the tests inasmuch as measuring the IOP could not take into account every conceivable deviations in the eyeball walls’ density, flexibility, structural form and other characteristics. Additionally, there are known variations among ethnic divisions in the structure of the eyeball, so the corneal dissimilarities may well be endless.

The effects of glaucoma

The effect of glaucoma on afflicted individuals may be discerned in their actions and accidents. Sufferers tend to go slow because they do not easily see what is before them, and consequently suffer more falls than average. The continuous looking down to see what they step on lead to posture deformities. But, according to new reports, vehicular accidents concerning persons with glaucoma are 50% lower than those with none of the defecgt. This is credited to greater carefulness practiced by those who preclusion of driving circumstances perilous for them. There are at all times positive and negative sides of everything.

Do you have glaucoma?

If you have blurry or indistinct vision, perhaps you must have your eyes checked for glaucoma. There are therapies and remedial methods on how to reduce its results, if not totally heal a person of the eye disease.
