When in a patient diagnosis as any damage, he asks a doctor or itself, what are he done is not right,why this pathology attacked his, and do not worry itself of these questions, if glaucoma found.

As a one mistake is bad attention to itself, as even you are nothing worried, and you are not asked in specialist, and remember visit oculist is not rare,just one time/year.Today picture is paradox, as and researches methods are many, to help a find glaucoma, high effectively drugs, surgery methods, laser, therefore today are founding are hard diseases, where is happening in our fast rhythm life for the health care, as dispanserization  we are forgot about, but an open agular  glaucoma is very insidious on begin stage, she is,like silence, hide, as doctor finds her on begin stage, when a cure is effectively, just in regular medics checkers, as this is not your fault in glaucoma display, as wearing glasses,loading on eyes, wearing lenses,weak light, lie in to read, bad meal, as not leading to pressure of intraocular, but timely visiting oculist, as a timely keeping for vision caring as checking these factors for glaucoma display,thus you are in risk.
Age, as with aging organism is mud, pressure in eyes rising, into eye liquid is lowering, but pressure not high still, and glaucoma still not happening, but answers are about why she is after 40 years happening or not is poor answer.
Genetically,as not an all, no matter would you has glaucoma or not, if you family had her.

Anomaly refraction, in hypermetropia is risk for close agular glaucoma is higher, as in small eye a lens is big,and disproportionate, as with age a size for natural lens rising,and iris to the front moving,closing a corner before camera is a base liquid outflow, and found is a high sensitiveness  to the pressure in eye rising is myopic eye, thus in myopia had been a found a more low norm for intraocular pressure, than in emmetropia.

Angiosclerosis, where in sclerosis of arteries or arteriosclerosis,leading to the narrowing vessels, a blood current to the organs is low, as blood circulation failure is a base pathogenesis for many diseases,and glaucoma in.

But a right  dependency for glaucoma of arteriosclerosis is not had.

Sex, yes in a few sex affiliation.

Race affiliation.
As negroid race patients are having a high intraocular pressure, as glaucoma display and on early age, as in Japanese she meeting as glaucoma with a low pressure, in Asians prevalent as closed angle glaucoma.

in glaucoma as vision of field slowly narrowing, as not aches feeling, but patients are doctors visiting on a latest stage.
First stage is beginning, 2 nd and, third is far entering and 4 as terminal..
