Diagnosis and treatment

Diagnosing glaucoma

Glaucoma is usually picked up during a routine eye test, often before it causes any noticeable symptoms. Other tests are usually needed afterwards to diagnose and monitor the condition.

It's important to have regular eye tests so problems such as glaucoma can be diagnosed and treated as early as possible. Early treatment can help stop your vision becoming severely affected.

You should have an eye test at least every 2 years. If you're at a higher risk of glaucoma – for example, if you have a close relative with it – you may be advised to have more frequent tests.

You can get an eye test at a local opticians, and the tests are carried out by an optometrist. Find an optician near you.

Some people can receive free eye tests on the NHS. Find out if you're entitled to free NHS eye tests.

Treatment for glaucoma

It's not possible to reverse any loss of vision that occurred before glaucoma was diagnosed, but treatment can help stop your vision getting worse.

The treatment recommended for you will depend on the type of glaucoma you have, but the options are:

• eyedrops – to reduce the pressure in your eyes
• laser treatment – to open up the blocked drainage tubes or reduce the production of fluid in your eyes
• surgery – to improve the drainage of fluid

You'll also probably need regular appointments to monitor your condition and check the treatment is working.

After glaucoma surgery

After surgery, your eye might water and be red, and your vision may be slightly blurred for up to 6 weeks but should return to normal.

The hospital will give you advice about which activities you can do while you recover. Most people are advised to keep their eye dry, and avoid driving, reading and heavy lifting for at least a week.
