Damages in the optical nerve caused by an increase of pressure in the interior of the eye that give like result the loss of the vision.

There are four types of glaucoma:

Primary Glaucoma of open angle.

Congenital Glaucoma.

Secondary Glaucoma.

Glaucoma of closed angle.


In the Glaucomas secondary, it depends on the underlying cause.

Glaucomas of closed angle usually is solved perfectly with the surgery.

Glaucoma of open angle does not have definitive treatment, but the medication allows to conserve the vision during long time.

Diagnosis and treatment.

Diagnosis the increase of the intraocular pressure is confirmed by means of the test of the tonometría.

By means of oftalmoscopio the type of glaucoma studies and by means of the campimetría the affectation of the field of view is valued.


According to the type of glaucoma, debera ':

to take part surgically to drain watery humor in case of glaucomas of close angle.

or to give medication to reduce the intraocular tension, in those of open angle.


Loss of the vision.


To measure the ocular tension, at least once to the year, after the 40.

Factors of risk.

Age superior to 40 years.

Familiar history of glaucoma.

Mellitus Diabetes.


The previous camera of the eye (between the cornea or girl and the crystalline or lens) is bathed by a liquid, the watery humor, that takes place in the rainbow and evacúa towards the blood in its periphery. Glaucoma appears when this watery humor takes place in excess or it is eliminated in smaller amount of the necessary one.

An impediment in its elimination in glaucomas of closed angle takes place, usually secondary, or in glaucomas congenital, in which the water - drainage channels are not developed suitably.

In glaucomas of open angle an overproduction of the liquid, of unknown causes takes place.

Signs and symptoms.

The most characteristic symptoms are, in glaucoma of closed angle:

Strong ocular pains and head.

Reddening of the eye.

Blurred vision.

Halos in the vision, mainly of objects very illuminated.

Tension in the ocular globe (it is felt stony, without yielding to the pressure)

Expanded pupil and fixes (it is not closed with the light)

The most characteristic symptoms are, in glaucoma of open angle (when taking place more slowly)

Gradual establishment.

Loss of peripheral vision (is seen except the edges, until arriving at the denominated "vision in tunnel": as if the things through a tube were watched)

Blurred vision.

Halos in the vision, mainly of objects very illuminated.

Difficulty for the perception of the colors.
