“I have been told that I have glaucoma (or I am at risk of developing glaucoma) but what is it ?”
Glaucoma is a disease process where the optic nerve (the main “pipe” carrying visual signals from the eye to the brain) is progressively damaged.
It is usually caused by elevated pressure inside the eye (“intraocular pressure” or “IOP”). Rarely, glaucoma can develop despite a perceived normal eye pressure but this is usually due to the influence of other factors.
This excellent video from the National Eye Institute, NIH (USA) explains glaucoma very effectively
