Diabetes is a long-term condition caused by too much glucose, a type of sugar, in the blood. It is also known as diabetes mellitus.
There are two main types of diabetes, which are explained below:
- Type I diabetes
- Type II diabetes
Normally, the amount of sugar in the blood is controlled by a hormone called insulin, which is produced by the pancreas. The pancreas is a gland behind the stomach. When food is digested and enters your bloodstream, insulin moves any glucose out of the blood and into cells, where it is broken down to produce energy.
However, in people with diabetes, the body is unable to break down glucose into energy. This is because there is either not enough insulin to move the glucose, or because the insulin that is there does not work properly.
Our specialist diabetes team will provide you with support, regular reviews and the day-to-day care of your needs.
All Diabetic patients are entitled to an annual review. The Practice will normally contact you if yours is due. The review takes place in two parts – a data collection appointment and where appropriate, a follow up care plan appointment. If you feel you have been missed, or require a more urgent review, then please contact the Practice to arrange an appointment.
At the initial data collection appointment, your blood pressure, weight, urine, feet and well-being will be checked. It is necessary for you to bring an early morning urine sample with you. Following your initial appointment, a care plan booklet will be sent to you and if necessary, an appointment with your GP or one of our specialist nurses will be arranged.
NHS launches new online support for people with diabetes during Covid-19
New online tools for people living with diabetes are now available to help people manage their condition during the coronavirus pandemic. Three new services allow people to manage their condition online, with a range of videos and training available on each app for children and adults. Patients will be offered advice on treatment and care, as well as training to adopt healthy behaviours on diet and exercise. This remote support will complement patients’ appointments, many of which have been going ahead throughout the pandemic, through video consultations or via telephone, and more recently in COVID protected areas.

> Diabetic Eye Screening
Diabetic eye screening is a key part of diabetes care. People with diabetes are at risk of damage from diabetic retinopathy, a condition that can lead to sight loss if it’s not treated.
Diabetic retinopathy is one of the most common causes of sight loss among people of working age.
It occurs when diabetes affects small blood vessels, damaging the part of the eye called the retina. When the blood vessels in the central area of the retina (the macula) are affected, it’s known as diabetic maculopathy.
People with diabetes should also see their optician every two years for a regular eye test. Diabetic eye screening is specifically for diabetic retinopathy and can’t be relied upon for other conditions.
Why eye screening is needed
Screening is a way of detecting the condition early before you notice any changes to your vision. Diabetic retinopathy doesn’t usually cause any noticeable symptoms in the early stages.
If retinopathy is detected early enough, treatment can stop it getting worse. Otherwise, by the time symptoms become noticeable, it can be much more difficult to treat. This is why the NHS Diabetic Eye Screening Programme was introduced.
Everyone aged 12 and over with diabetes is offered screening once a year. Diabetic retinopathy is extremely unusual in children with diabetes who are under the age of 12.
The check takes about half an hour and involves examining the back of the eyes and taking photographs of the retina.
When diabetic eye screening is offered
Everyone with diabetes who is 12 years of age or over should be invited to have their eyes screened once a year.
You should receive a letter from your local Diabetic Eye Screening Service inviting you to attend a screening appointment. The letter will include a leaflet about diabetic eye screening.
People with diabetes can opt out of the screening programme if they choose. They should confirm this decision in writing to the screening service that has invited them for diabetic eye screening
Contact your local screening service or your GP if you haven’t received a letter and your appointment is overdue. You can look up your local screening service here – your service will be the one nearest to your GP surgery.
The invitation will say where you need to go. This may be your GP surgery, your local hospital, a local optician’s practice, or another nearby clinic.
Bring all the glasses and contact lenses you wear, along with lens solution for contacts.
If you have sight problems in between screening appointments, such as sudden vision loss or a deterioration in your vision, seek immediate medical advice. Don’t wait until your next screening appointment.
Diabetic eye screening in pregnancy
If you have diabetes and become pregnant, you’ll need special care as there are risks to both mother and baby associated with the condition.
You’ll be offered additional tests for diabetic retinopathy at or soon after your first antenatal clinic visit, and also after 28 weeks of pregnancy.
If the early stages of retinopathy are found at the first screening, you’ll also be offered another test between 16 and 20 weeks of pregnancy.
If serious retinopathy is found at any screening, you’ll be referred to an eye specialist.
Some women who don’t have diabetes can develop hyperglycaemia (high blood sugar) during pregnancy. This is known as gestational diabetes.
Pregnant women who develop gestational diabetes aren’t offered screening for diabetic retinopathy.
What happens during diabetic eye screening
The screening appointment should last about 30 minutes.
When you arrive, the procedure will be explained to you. If you have any questions, ask the healthcare professional who is treating you.
You’ll be given eye drops to enlarge your pupils, which takes between 15 and 20 minutes, and photographs of your retina will be taken.
There will be a flash of light each time a photograph is taken, but the camera won’t touch your eye. Although the light is bright, it shouldn’t be uncomfortable.
The eye drops may cause your eyes to sting slightly, and after about 15 minutes your vision will be blurred. You may find it difficult to focus on objects that are close to you.
Depending on the type of eye drops used, the blurring can last between two and six hours. You won’t be able to drive home from your appointment, so you may want to bring someone with you.
After the screening procedure, you may also find that everything looks very bright. You may want to take a pair of sunglasses to wear afterwards.
In very rare cases, the eye drops can cause a sudden pressure increase within the eye. This requires prompt treatment at an eye unit.
The symptoms of a pressure increase are:
- pain or severe discomfort in your eye
- redness of the white of your eye
- constantly blurred vision, sometimes with rainbow halos around lights
If you experience any of these symptoms after screening, go back to the screening centre or your nearest accident and emergency (A&E) department.
Your screening results
Within six weeks, both you and your GP should receive a letter letting you know your results.
You won’t get the results immediately as the photographs need to be studied by a number of different healthcare professionals, including someone who is trained in identifying and grading retinopathy.
The screening results may show either:
- no retinopathy
- background retinopathy – also called stage one retinopathy
- degrees of referable retinopathy – this means retinopathy that requires referral to an eye specialist for further assessment and treatment
You may need to have a further assessment if:
- the photographs aren’t clear enough to give an accurate result
- you have retinopathy that could affect your sight and follow-up treatment is needed
- you have retinopathy that needs to be checked more than once a year
- other eye conditions are detected, such as glaucoma (a group of eye conditions that affect vision) or cataracts (cloudy patches in the lens of the eye)
If your results show no retinopathy or background retinopathy, you’ll be invited back for another screening appointment a year later.
You can also reduce your risk of developing diabetic retinopathy in the future by controlling your blood sugar levels and blood pressure.
Read more about preventing diabetic retinopathy.
If screening detects signs that diabetic retinopathy or maculopathy is threatening your sight, you’ll be given information about how far the condition has progressed. This will determine the type of treatment you receive.
Read about the treatment options for diabetic retinopathy and maculopathy.
If you have questions about your results, contact your local diabetic eye screening service. Their details should be on the letter you received from them. Alternatively, you can find your local screening service here.
