Chronic glaucoma - a common cause of blindness

- High pressure in the eye increases the risk of developing chronic glaucoma. The disease occurs after the age of 40 and then increases in frequency with age. 

- The diagnosis of chronic glaucoma is made on the basis of characteristic bleaching of the optic nerve and failure of the visual field.

- Chronic glaucoma can often be treated by lowering the eye pressure with eye drops, laser or surgery.

In Denmark

Chronic glaucoma is one of the most common causes of blindness in Denmark, but the exact incidence is unknown.

It is estimated that a few percent of the population over the age of 40 have chronic glaucoma. The incidence increases with age.


A person with chronic glaucoma has neither pain nor other discomfort in the eyes. Most cases of chronic glaucoma are discovered by chance during a routine examination of the eyes.

The sharp vision, which one uses to read and to watch TV with, is usually preserved for the longest time. Only when there has been significant damage to the optic nerve will you notice the outcomes in the visual field. Then it can be difficult to prevent further aggravation.

Prevention - regular check-ups with an ophthalmologist

If you have a hereditary predisposition to chronic glaucoma, you should have your eyes examined once a year by an ophthalmologist.

If one experiences overlooking objects in the field of view, you should seek professional help.

It is important to be aware that treating glaucoma is usually lifelong. The purpose of the treatment is to prevent the vision from deteriorating. There is no treatment that can improve vision and there can be side effects associated with all the types of treatments that are available.
