What is Glaucoma?
Glaucoma is the name given to a group of eye conditions where the optic nerve at the back of the eye is damaged. It is often linked with raised pressure within the eye, although the eye pressure can sometimes be normal. Glaucoma can cause problems with the peripheral vision (side vision) and, if left untreated, can cause permanent damage. With early detection and treatment, further damage to vision can be prevented. The condition often happens in both eyes, although sometimes it affects one eye more than the other. Glaucoma is one of the leading causes of severe sight impairment.
Anyone can develop glaucoma. The risk of developing glaucoma goes up if you are:
- Aged over 40
- Closely related to someone with glaucoma. If you are diagnosed with glaucoma, it is important to let your close relatives know as they may be at increased risk of developing the disease.
- Of black African or black Caribbean ethnic origin.
- Very short sighted
Other eye conditions can sometimes cause glaucoma as a side effect.
Glaucoma may not have symptoms and this is why it is very important to have regular sight tests. Click on an option below to find out more about the symptoms.
These symptoms can develop very quickly. Your eye might become very red and painful, you can get headaches and feel sick, and you may notice coloured halos around lights. This is a medical emergency. If you notice any of these symptoms, you should go to an accident and emergency (A&E) department immediately.

Open-angle glaucoma is usually treated with eye drops which reduce the pressure in the eye. You will need to use these daily and you will be monitored regularly at the hospital. Occasionally people with open-angle glaucoma need surgery to control the pressure.
Closed-angle glaucoma can damage the eye quickly. It’s treated at first by drops and tablets and sometimes by drugs direct into the bloodstream to quickly reduce the pressure in the eye. Laser treatment is often needed later to allow the fluid to flow through the eye better. People with closed-angle glaucoma may need surgery if laser treatment is not successful.
Our OCT scanner can help with early detection of glaucoma. We recommend it for all our patients with a family history of glaucoma. For an OCT assessment please call us to book your eye health appointment.
