Glaucoma
Glaucoma is a serious eye condition that can cause permanent vision loss if left untreated. This is because it often develops slowly and without pain, regular eye examinations are essential for early detection.
What is glaucoma?
Glaucoma is a group of eye conditions that damage the optic nerve, leading to loss of peripheral (side) vision. This damage is often caused by increased pressure inside the eye, although in some cases the optic nerve is more sensitive to normal pressure levels.
Glaucoma usually develops slowly and without noticeable symptoms. Many people are unaware they have it until significant damage has already occurred. Any vision loss caused by glaucoma cannot be reversed.
Why early detection is so important
Glaucoma progresses slowly and painlessly meaning damage can occur long before symptoms are noticed. Regular eye tests are the most effective way to detect glaucoma early and protect your remaining vision.
Under the NHS, free eye examinations are available for people over 40 who have a close relative with glaucoma.
Who is at risk of developing glaucoma?
- People with close family history of glaucoma
- Individuals of African or Caribbean Heritage
- People aged over 40
- Those who are very short sighted
How is glaucoma detected?
At the early stages, glaucoma does not usually cause noticeable symptoms. Eye examinations are therefore essential to detect the condition early. The tests we perform at Home Eyecare to detect glaucoma:
- Examination of the optic nerve at the back of the eye using specialist equipment
- Measurement of eye pressure using a gentle puff of air
- Visual field testing to assess peripheral vision
What happens if I am diagnosed with glaucoma?
If your optometrist believes you may be at risk of glaucoma, you will be referred to an ophthalmologist for further assessment.
If glaucoma is confirmed, treatment usually involves daily eye drops to control eye pressure. Although glaucoma cannot be cured, treatment is very effective at slowing progression and preserving vision.
It is essential to continue treatment and attend follow-up appointments even if your vision feels normal.
Although glaucoma causes permanent damage, most people maintain good functional vision for life with early detection, treatment and regular monitoring.
Concerned about glaucoma?
If you are at risk or due for an eye examination, a professional eye test can help detect glaucoma early and protect your sight.
