Glaucoma

What is glaucoma?

Glaucoma is a serious disease that is considered a major cause of blindness in Spain. Over a million people suffer and nearly 50% of them know that glaucoma is affected, as it is an eye disease that in most cases no symptoms, which is why glaucoma is known as "the silent disease of the eyes."

This condition is caused by an injury of the optic nerve caused, in general, increased ocular tension as a result of poor drainage of aqueous humor from our eyes. This injury produces irreparable damage to the optic nerve, which causes a progressive loss of vision, and even can lead to total blindness.

Symptoms

If you suffer from glaucoma may not initially detected symptoms. If you notice symptoms, it is possible that his vision has already been significantly affected.

Some common symptoms are:

  • Frequent change of glasses because none is satisfactory.
  • Difficulty seeing in dark places (eg cinema).
  • Loss of peripheral vision.
  • Rainbow in a ring around the lights.
  • Difficulties in vision focus on very close objects.

These symptoms are not always signs of glaucoma, but if you notice any of them in, it is advisable to go to an ophthalmologist.


Treatment

The goal of treatment is to preserve useful vision by reducing intraocular pressure. The lesions are usually irreversible established, therefore, treatment is directed to stop disease progress and prevent visual impairment.

Normally used eye drops that help produce less fluid within the eye or to facilitate its drainage. Is the initial treatment of the disease, but the decrease in pressure does not usually exceed 30%.

When the "silent blindness" has appeared, the solution to our problem through surgery. Trabeculectomy has been the standard operation in the surgical treatment of glaucoma, although new developments point to a new less invasive surgery.

In our center we practice called escleroctomia not deep drilling, intervention which avoided penetrating the interior of the eye. This will significantly reduce the complications associated with glaucoma surgery, as these are mainly due to the sharp decrease of the tension caused perforating techniques. The postoperative period is much more comfortable for the patient and their recovery is much faster.

How to Prevent Glaucoma

Examining prevention of glaucoma is painless and fast. Everyone older than 35 years should at least once a year, take the intraocular pressure, pachymetry get a (measure the thickness of the cornea) and performed a visual field.

If your eye pressure is very close to the level set parameters as normal should be put under control in order to explore possible future increases.

If the pressure is above normal, the specialist will observe the optic nerve to determine if it has been damaged and detect if there is loss of visual field to confirm the diagnosis.

A big help to us is through the computerized perimetry, as in the case of suspected glaucoma, gives unmistakable signs of confirmation or not. If confirmed glaucoma, establishes a fundamental pattern of prognosis and treatment.

The advent of optical coherence tomography and GDX allow us to prevent the occurrence of this disease making early diagnosis and continuous monitoring.

Glaucoma end

1. Elevated intraocular pressure: when the higher pressure of the eye, it'll produce nerve injury we call glaucoma. 

2. Glaucoma Family history: having a parent or sister with glaucoma increases the risk of the disease. It is advisable to review eye when having close relatives with glaucoma. 

3. Myopia: myopia eyes with optic nerves are more susceptible to injury than non-myopic eyes. 

4. Ocular trauma old. 

5. Pressure normal: a type of glaucoma can occur even have normotensive glaucoma called normal pressure, so it is very important to get an annual review with fundus and study optic nerve.

In elderly patients. Glaucoma is more common after the age of 50 and especially after 60 years.
