How glaucoma forms
Glaucoma are those kinds of eye disorders that continually damage the optic nerves, altering the optic nerve head and the retina.

A new third theory suggests that modifies in the inside pressures of the eye orb damage 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]
Normally, when glaucoma is suspected, three undertaken to reveal its incidence. The initial test is optic disc assessment, which gauges the optic discs relative to to a set of averages, 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 backdrop color and the color of the item in the front. There are a few categories of eye impairments classified under this method, dealing 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 eye. This seems to be the least dependable among the tests inasmuch as measuring the IOP cannot consider all conceivable variation in the eyeball walls’ thickness, elasticity, curvature and other properties. Furthermore, there are recognizes differences among ethnic divisions in the structure of the eyeball, so the corneal dissimilarities may well be endless.
