Many instances of impaired vision have been attributed to getting old, and most of these may be accurate. But your Flint optometrist can tell you that the bases why aging can engender vision degradation has not been explained much, so that is has turned to nearly a catch-all phrase for numerous problems correlated with it. However, medicine knows glaucoma as one of the reasons for poor vision, so you can ask your optometrist in Flint for the symptoms 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 says that the inordinate pressure of the aqueous humor sets off damage to the tissues of the optic nerve, while the (2) ‘vascular’ theory proposes that optic deterioration is due to tissues decaying from low nourishment. A new third theory suggests that changes in the internal pressures of the eye orb injure the retinal and optic structure so that they turn to be more easily damaged. But this third theory is up to now under detailed research.
Glaucoma detection Usually, when glaucoma is supposed, three procedures are made to detect its incidence. The first is optic disc assessment, which measures the optic discs relative to to a series of averages, so that variation from normal may be owed to the ailment. The next, is a visual field assessment, calculates how the eye sees the difference between a background color and the color of the item in the front. There are a few categories of eye defects classified under this method, dealing generally with [damage|injury} to the retina. Visual field assessment tests are normally performed againwhen glaucoma is detected, just for accuracyof prognosis.
The third method is IOP test that measures the intraocular pressure inside the eye. This appears to be the least dependable among the assessments inasmuch as measuring the IOP cannot consider every conceivable deviations in the eyeball walls’ thickness, elasticity, curvature and other properties. Furthermore, there are known variations among ethnic divisions in the structure of the eyeball, so the corneal variations may well be infinite.
The effects of glaucoma
The effect of glaucoma on afflicted individuals may be seen in their movements and mishaps. Patients tend to go slow because they do not readily see what is before them, and consequently suffer more accidents than average. The constant peering down to see what they walk on lead to physical deformities. But, according to new statistics, 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 dangerous for them. There are always positive and negative effects of anything.
