Many instances of degraded vision have been attributed to getting old, and many of these may be true. But your Flint optometrist can tell you that the bases why growing old can cause vision degradation has not been explained much, so that is has turned to almost a catch-all phrase for many troubles associated with it. However, medicine recognizes glaucoma as one of the reasons for poor vision, so you can query your optometrist in Flint for the indicators of glaucoma.

How glaucoma forms

Glaucoma are those types of eye diseases that continually impair 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 abnormal pressure of the aqueous humor sets off injury to the fibers of the optic nerve, while the (2) ‘vascular’ theory insists that optic deterioration is due to tissues wasting from low nourishment. A new third theory postulates that modifies in the inside pressures of the eye orb injure the retinal and optic construction so that they become more easily damaged. But this third theory is still under close study.

Glaucoma determination tests]

Normally, when glaucoma is suspected, three undertaken to detect its presence. The initial test is optic disc assessment, which gauges the optic discs relative to to a series of rules, so that difference from normal may be due to the ailment. The next, is a visual field assessment, calculates how the eye sees the variation between a background color and the color of the item in the front. There are several categories of eye impairments classified under this method, dealing generally with [damage|injury} to the retina. Visual field assessment tests are normally performed againwhen glaucoma is seen, just for accuracyof prognosis.

The third way is IOP test that assesses the intraocular pressure inside the eyeball. This seems to be the least reliable among the tests since measuring the IOP could not take into account every conceivable deviations in the corneal thickness, elasticity, curvature and other characteristics. Additionally, there are recognizes differences among races in the structure of the eye, so the corneal dissimilarities may well be infinite.

The effects of glaucoma

The impact of glaucoma on afflicted individuals may be seen in their movements and mishaps. Sufferers are likely to go slow because they do not readily see what is in front of them, and consequently suffer more accidents than normal. The continuous looking downwards to see what they walk on lead to physical deformities. But, according to new reports, vehicular accidents involving persons with glaucoma are 50% less 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.
