Progressive blindness

The visual nerve connects the eye to the brain which transmits all visual impressions. With glaucoma, this nerve is slowly dying. This leads to a progressive loss of the outer visual field. 

At a very late stage also the central visual field is destroyed. It is only in this advanced state that patients notice blind spots.
A therapy can only lead to a standstill of the disease but not to an improvement of the visual field.

Worldwide, glaucoma is the second leading cause for blindness both in industrial nations and developing countries.
