Glaucoma is a condition often affecting the sight of both eyes. Very few symptoms may be detected at the early stages of development, which can mean that the condition is completely missed.
A late diagnosis of symptoms, or misdiagnosis for another eye condition can result in complete loss of vision.
However, sight can be preserved and irreversible blindness can be prevented if glaucoma is correctly diagnosed and treated as quickly..
Your GP / doctor or eye specialist may have been negligent ’ if a delay in referral and diagnosis led to:
To bring a successful clinical negligence claim it is necessary to prove that the care and treatment received fell below a generally accepted standard, and caused preventable harm or loss.

What is glaucoma?
Glaucoma is a disease of the eye in which fluid constantly produced by the eye fails to drain away fast enough. Both eyes can be affected although one eye may develop the condition quicker than the other one.
The build up of excess fluid - known as the intraocular pressure – can cause damage to the retina (light-sensitive nerve tissue at the back of the eye) and the optic nerve, which sends signals from the eye to the brain.
A delay in treating damage to the nerve can lead to irreversible blindness.
There are four main types of glaucoma:
Chronic or Primary Open-Angle Glaucoma (POAG) – the most common type of glaucoma, which develops very slowly.
Symptoms: a gradual of loss of vision which starts at the edge of the eye, usually in the shape of an arc ‘seen’ a little above and/or below the centre of vision when looking straight ahead. The onset of symptoms is not always noticed or diagnosed before the disease has spread both outwards and inwards, and permanent damage has already occurred.
Acute Angle-Closure Glaucoma – which can develop rapidly with a sudden, painful build-up of pressure. Symptoms of acute glaucoma are not constant, but can last for one or two hours and cause further damage.
Secondary Glaucoma – mainly occurs as a result of an eye injury or another eye condition, such as inflammation of the middle layer of the eye.
Developmental Glaucoma (congenital glaucoma) – a rare but sometimes serious type of glaucoma which occurs in very young children.
Other types of glaucoma include:
Low-tension glaucoma - where eye pressure is normal but optic nerve damage still occurs.
Pigmentary glaucoma – which can develop during early or middle adulthood and may occur after exercise or sport. Pigment granules from the back of the iris are dispersed within the eye. Fluid flow is affected and leads to a rise in eye pressure.
Glaucoma risk factors
Primary Open-Angle Glaucoma (POAG) - factors which can increase your risk of developing the most common type of slowly-developing glaucoma, are:
Acute Angle-Closure Glaucoma - People of Asian origin are more at risk of developing this rapidly progressive form compared with those from other ethnic groups.
Diagnosis of glaucoma will require a number of important tests to be carried out, as follows:
Eye pressure test (tonometry) - measures the pressure inside the eye (intraocular pressure).
A small amount of dye is placed onto the cornea – the transparent layer of tissue that covers the front of the eye. A blue light from the head of the tonometer device is held against the eye to measure the pressure.
Central corneal thickness – the depth of the cornea is also measured because of the affect upon internal eye pressure measurements.
Gonioscopy - a lens is placed against the eye to examine the front outer edge between the cornea and the iris (the coloured part of your eye) where the fluid should drain out of the eye. This test can help to determine whether the angle is open or closed (blocked).
Visual field test (perimetry) – a check for missing areas of vision. A sequence of light spots will be displayed and the patient is asked which ones can be seen. Some dots will appear in the area known as peripheral vision (around the sides of the eyeball), which is where glaucoma begins. If spots are not seen in the peripheral vision, it may indicate the glaucoma has caused damage.
Optic nerve assessment – to determine if the optic nerve, which sends signals from the eye to the brain has been damaged. The pupils are enlarged by the use of eye drops and the eyes are then examined using a microscope with a very bright light, known as a slit lamp.
If glaucoma is suspected - a referral to an eye specialist should be promptly arranged for further tests to confirm a diagnosis and to determine:
If Closed Angle Glaucoma is suspected - an immediate referral for treatment must take place.
Once a diagnosis has been confirmed, the treatments for Glaucoma can involve:
Any damage to the eyes cannot be reversed, which means that treatment will simply aim to control the condition and minimise future damage.
Primary Open-Angle Glaucoma (POAG) – Patients will need lifelong monitoring so that any progression of visual damage can be detected.
Glaucoma – claiming for negligence
Early and accurate diagnosis and treatment are crucial to preventing glaucoma from causing any further damage to the eyes and the ability to see.
You may have good grounds to believe that the standard of appropriate care fell below expectation if your GP or doctor was found responsible for:
