Glaucoma is an eye condition where your optic nerve is damaged by the pressure of the fluid inside your eye. Most types of glaucoma have no symptoms, so a regular eye test is the only way to know you have the condition. Treatment with drops can often prevent glaucoma causing sight loss.
Our Understanding Glaucoma guide is accredited by the Royal College of Ophthalmologists. It’s designed to give you a detailed understanding of your eye condition and helpful advice on next steps.
Glaucoma is the name given to a group of eye conditions that cause permanent sight loss by damaging your optic nerve.
You may not notice any difference in your vision because glaucoma affects your peripheral vision (also known as your side vision) first. As your peripheral vision is not as sensitive as your central vision, it’s difficult to notice any early changes to your vision – but your sight is being damaged.
There is no treatment to restore sight loss caused by glaucoma but treatments, such as eye drops and laser surgery, can help prevent sight loss from happening.
Glaucoma can be caused by raised eye pressure or a weakness in your optic nerve.
Your eye needs a certain amount of pressure to keep the eyeball healthy and in the right shape. But if the pressure is too high, it can cause your optic nerve to become damaged at the point where it leaves your eye.
Lots of people who have treatment for their glaucoma don't have any sight problems because the treatment prevents sight loss.
