What is glaucoma?
Glaucoma affects over 1 million people in Spain and includes a group of neurodegenerative diseases that cause progressive, irreversible damage to the optic nerve. This structure is key for vision, as it transmits the nerve impulses from the eye (more specifically from the retina) to the brain so that it can interpret them and you can see the images. As a result of the progressive loss of optic nerve fibres, the visual field is gradually reduced and can result in blindness if the disease is not slowed down.
There are several types of glaucoma, which are primarily grouped into open-angle glaucoma (the most common, accounting for 90% of all cases) and closed-angle glaucoma, depending on the opening of the angle of the eye where the structures involved in the disease are located.
Glaucoma can also be classified according to its time of appearance (congenital, childhood, juvenile or adult) and its origins, which might be primary or secondary to other ocular processes or systematic diseases, such as diabetes.
