Chronic Glaucoma

Below we explain what Chronic Glaucoma is, what the risk factors for developing it are and how the condition is diagnosed and treated.

Glaucoma is the name for a group of eye conditions which cause optic nerve damage and can affect vision.  Chronic Glaucoma is the most common type of glaucoma and is outlined here . Information on the other types of glaucoma can be found by referring to the further reading section below.
Damage to the optic nerve (the nerve from the eye to the brain), most often caused by raised eye pressure, leads to progressive loss of vision. This is very difficult to detect in the early stages and is irreversible. Left untreated all sight may eventually be lost .

The risk is increased by:

• Age: 5% of people aged over 65 years develop chronic glaucoma
• Race: People of West African origin are more likely to develop chronic glaucoma
• Family: Having a previously affected close relative increases the risk
• Short Sight: Being very short sighted increases the risk
• Diabetes: People with diabetes are more at risk

Symptoms

• Peripheral vision gradually gets worse
• Tunnel vision

Assessment

Diagnosis is difficult because there are no symptoms until the disease is well advanced. Routine yearly sight tests from the age of 50 are the best protection. An Optometrist will carry out tests to detect or exclude the disease and will refer you to an eye specialist if necessary .

Treatment

Once diagnosed, it is important to have regular check-ups with an Ophthalmologist.  Treatment usually begins with eye drops to lower eye pressure. Other treatments such as laser therapy or surgery may be advised, depending on whether the disease is stable or progressing.
