Glaucoma

Glaucoma gradually reduces the vision field without the patient noticing any symptoms in the early stages of this disease.

Glaucoma is known as a group of diseases featured by the progressive damage to the optic nerve that transmits visual information to the brain.

The main factor involved is increased pressure inside the eye. Its incidence increases with age, particularly over the age of 40.

Progressive damage to the nerve leads to a continuous loss of the visual field, which can lead to blindness.

At Clínica Oftalmológica Castro we recommend regular eye check ups from the age of 40 onwards. This is the stage in which age-related symptoms of eye diseases may start to appear.

Why does it occur?

The fluid that is continually renewed inside the eye (aqueous humour) has difficulty (due to various reasons) in leaving the eye and this leads to increased pressure inside it.

How does the patient perceive this?

Unfortunately, the patient does not notice any symptoms until advanced stages in which the nerve shows considerable damage that involves loss of the visual field and an impact on the daily life, affecting driving for example.

How is it detected?

With complete eye check ups every year or every two years.
By monitoring eye pressure and the condition of the optic nerve.
Complementary check ups may be necessary, such as pachymetry (measurement of corneal thickness), a review of the visual field or an optical coherence tomography (OCT), which is similar to a CAT scan of the optic nerve.

What is the treatment for glaucoma?

The main objective is to lower the eye pressure in those people in whom it is considered to be high.

This can be performed by the use of different drugs (administered as eye drops or tablets) or with laser techniques or conventional surgery, to be determined by the specialist.

Early detection of the disease is very important to avoid progressive deterioration and to preserve the vision, as the damage caused to the optic nerve and the consequent vision loss are irreversible.
