A lot of instances of degraded vision have been ascribed to growing old, and most of these may be accurate. But your Flint optometrist can tell you that the reasons why growing old can engender vision decline has not been clarified much, so that is has turned to nearly a catch-all phrase for many troubles correlated with it. However, medicine recognizes glaucoma as one of the reasons 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 continually damage the optic nerves, altering the optic nerve head and the retina. Two theories have been proposed as to its cause: (1) the ‘mechanical’ theory which states that the inordinate stress of the aqueous humor causes damage to the fibers of the optic nerve, while the (2) ‘vascular’ theory proposes that optic deterioration is due to nerves wasting from lack of nourishment. A new third theory suggests that modifies in the internal pressures of the eye orb injure the retinal and optic construction so that they turn to be more easily damaged. But this third theory is still under close research.

Glaucoma determination tests]

supposed, three procedures are made to reveal its presence. The first is optic disc assessment, which gauges the optic discs relative to to a set of averages, so that variation from normal may be due to the disease. The second, is a visual field assessment, measures how the eye perceives the variation between a backdrop color and the color of the object in the front. There are several subdivisions of eye defects classified under this process, correlated mostly with [damage|injury} to the retina. Visual field assessment tests are normally repeatedwhen glaucoma is detected, just for precisionof prognosis.

The third way is IOP test that measures the intraocular pressure within the eyeball. This appears to be the least dependable among the assessments inasmuch as measuring the IOP could not take into account every conceivable variation in the corneal thickness, flexibility, curvature and other properties. Additionally, there are known variations among ethnic divisions in the construction of the eyeball, so the corneal dissimilarities may well be endless.

The effects of glaucoma

The effect of glaucoma on affected persons may be seen in their actions and mishaps. Patients tend to move slow because they cannot readily see what is before them, and as a result experience more falls than normal. The continuous looking downwards to see what they step on lead to posture deformations. But, according to new statistics, vehicular accidents involving persons with glaucoma are 50% less than those without the disease. This is credited to greater carefulness done by those who preclusion of driving conditions dangerous for them. There are always positive and negative effects of everything.

Do you have glaucoma?

If you have blurry or indistinct vision, perhaps you should have your eyes examined for glaucoma. There are therapies and remedial methods on how to reduce its effects, if not totally heal a patient of the eye impairment.
