Local structures of the eye and the pathogenesis of glaucoma patients,
such factors as age, gender, genetics, REFR has a close relationship,
with these high-risk factors of people which is glaucoma, acute onset
of adverse external factors stimulating cause at any time.

1, eye and systemic diseases.

2, anatomical factors: short shallow anterior Chamber, axial, Crystal
thickness, corneal diameter and short, resulting in stenosis of
anterior chamber angle, aqueous humor barrier-discharge, increased
intraocular pressure, glaucoma formation.

3, age, sex: open-angle multiple of 30 years or so, no significant
gender differences.Patients with angle-closure glaucoma patients with
over 45 years old 68.2% per cent, more women than men.

4, improper drug use.

5, bad living habits: smoking drinking, personal uncertainty,
irregular diet, Moody, habitual constipation, intractable insomnia.

6, genetic factors: glaucoma is a Polygenic disease, family history,
the incidence is higher than the 6 times with no family history, 13%
per cent of the total number of onset, incidence of relatives of
patients with 3.5%-cent.

7, refractive factor: refractive error in (myopia, hyperopia,
presbyopia) high incidence, one-third of myopia with or development
for open-angle glaucoma, hyperopia with angle-closure glaucoma.

Lack of sleep may be induced by glaucoma

Acute attack of glaucoma patients to ophthalmologists often
encountered the doctor.Sharp decline in patient eye redness, pain,
vision, and even nausea, vomiting, body does not apply.

Incidence of the patients can be monocular or binocular and, at the
onset of intraocular pressure is often as high as over 50mmHg (normal
intraocular pressure is 10~21mmHg), with fingers touch can feel eye
and hard as stone.

Former patients often stay up late and tired, and even some patients
tell their doctors just watching TV a long time.

So why do these conditions will cause glaucoma attack it?

Original, tired excessive, and sleep insufficient, and emotional
fluctuations, and diet does not section or engorgement, factors, can
effect vascular neural regulation Central, makes vascular Shu shrink
function disorders: while can makes capillaries expansion, vascular
permeability sexual increased, caused ciliary muscle edema, and Qian
moved, plug anterior chamber angle, makes room water outflow channel
blocked; on the can makes room water secretion too much, posterior
Chamber intraocular pressure high, around IRIS by pressure forward
moved and makes anterior chamber variable shallow, anterior chamber
angle variable narrow.These factors can cause a rapid rise in
intraocular pressure, eventually leading to acute attack of glaucoma.

Therefore, doctors call them cause of acute attack of glaucoma.This
shows that the life of glaucoma patients, emotional stability, defy
the law section, bearing in mind the stimulation is very important to
avoid negative factors.
