Eye screening is an important part of diabetes care.
A range of ocular diseases is associated with diabetes, which may lead to vision loss.
The most damaging condition is known as diabetic retinopathy.
This condition can lead to sight loss if it is not treated.
Diabetic retinopathy occurs when diabetes affects small blood vessels, damaging the part of the eye, called the retina.
Diabetic retinopathy is one of the most common causes of sight loss among people of working age.
Diabetic retinopathy does not usually cause any noticeable symptoms in the early stages.
Screening for diabetic retinopathy is a way of detecting the condition early, before you notice any changes to your vision.
If retinopathy is detected early enough, treatment can stop it getting worse. By the time symptoms become noticeable, it can be much more difficult to treat the condition.
The screening involves examining the back of the eyes and taking retinal photographs.
It is important to have regular eye examinations so that eye problems, such as glaucoma, can be diagnosed and treated as early as possible.
Glaucoma is an eye disease in which the optic nerve, which connects the eye to the brain, is damaged by the pressure of the fluid inside the eye. This is a sight threatening disease.
Glaucoma can be controlled by using eye drops to reduce the pressure in the eye.
