At Blue Fin Vision, our premier eye clinic in London, we often encounter patients with diabetic retinopathy disease. This condition is a common complication of diabetes that affects the retina, the light-sensitive tissue at the back of the eye. In this comprehensive guide, we’ll explore what diabetic retinopathy is, its causes, symptoms, and the cutting-edge treatments available
Understanding Diabetic Retinopathy
Diabetic retinopathy is a serious eye condition that occurs as a complication of diabetes. It develops when high blood sugar levels damage the blood vessels in the retina, leading to various vision problems. This condition is the leading cause of vision loss in working-age adults in the UK.
Key Facts About Diabetic Retinopathy:
- It affects people with both type 1 and type 2 diabetes
- The risk increases with the duration of diabetes
- Early stages may not present noticeable symptoms
- Regular eye screenings are crucial for early detection
Causes of Diabetic Retinopathy
Understanding the causes of diabetic retinopathy is essential for prevention and management. The primary factors contributing to this condition include:
- Prolonged High Blood Sugar Levels: Consistently elevated blood glucose damages the tiny blood vessels in the retina.
- Duration of Diabetes: The longer a person has diabetes, the higher the risk of developing retinopathy.
- Hypertension: High blood pressure can exacerbate damage to retinal blood vessels.
- Lipid Abnormalities: High cholesterol and triglycerides can contribute to the development of retinopathy.
- Pregnancy: Women with diabetes may experience rapid progression of retinopathy during pregnancy.
At Blue Fin Vision, our experienced ophthalmologists conduct thorough assessments to identify any underlying factors that may contribute to diabetic retinopathy.
Stages of Diabetic Retinopathy
Diabetic retinopathy typically progresses through four stages:
- Mild Non-proliferative Retinopathy (NPDR): Small areas of balloon-like swelling in the retina’s blood vessels, called microaneurysms, occur.
- Moderate Non-proliferative Retinopathy (NPDR): As the disease progresses, some blood vessels that nourish the retina become blocked.
- Severe Non-proliferative Retinopathy (NPDR): More blood vessels become blocked, depriving the retina of its blood supply. The retina signals for the growth of new blood vessels.
- Proliferative Diabetic Retinopathy (PDR): At this advanced stage, new blood vessels grow in the retina. These fragile vessels can leak, leading to vision loss and even retinal detachment.
Symptoms of Diabetic Retinopathy
Recognising the symptoms of diabetic retinopathy is crucial for early diagnosis and treatment. Common signs include:
- Blurred or fluctuating vision
- Impaired colour vision
- Dark or empty areas in your vision
- Difficulty seeing at night
- Sudden vision loss
- Floaters (dark spots or strings floating in your vision)
It’s important to note that diabetic retinopathy can develop gradually, and some people may not notice symptoms in the early stages. This underscores the importance of regular eye examinations for individuals with diabetes.
Diagnosing Diabetic Retinopathy
At our London eye clinic, we use state-of-the-art diagnostic tools to accurately identify and assess diabetic retinopathy:
- Dilated Eye Examination: This allows our specialists to thoroughly examine the retina and its blood vessels.
- Optical Coherence Tomography (OCT): This non-invasive imaging test provides detailed cross-sectional images of the retina, helping to assess macular oedema.
- Fluorescein Angiography: A special dye is injected into the arm, which then travels to the eye’s blood vessels, allowing us to identify any leaks or abnormalities.
- Fundus Photography: This captures detailed images of the retina, optic nerve, and blood vessels.
Early diagnosis is key to preventing further vision loss and implementing effective treatment strategies.
Treatment Options for Diabetic Retinopathy
While there’s no cure for diabetic retinopathy, several treatments can help manage the condition and prevent further vision loss. At Blue Fin Vision, we offer a range of advanced treatments tailored to each patient’s specific needs:
- Intravitreal Injections
These are a mainstay of treatment for diabetic retinopathy, particularly for diabetic macular oedema:
- Anti-VEGF Drugs: Medications such as aflibercept (Eylea), ranibizumab (Lucentis), bevacizumab (Avastin), and faricimab-svoa (Vabysmo) help reduce macular oedema and improve vision.
- Corticosteroids: These can help reduce inflammation and macular oedema in some cases.
- Laser Therapy
- Panretinal Photocoagulation: Used in proliferative diabetic retinopathy to reduce the total amount of retina, thereby decreasing oxygen demand and retinal hypoxia.
- Focal Laser Treatment: This can help reduce macular oedema by sealing leaking blood vessels.
- Vitrectomy
This surgical procedure may be necessary for advanced cases where there’s bleeding into the vitreous (the gel-like substance that fills the eye) or retinal detachment.
- Management of Underlying Conditions
- Controlling blood sugar levels, blood pressure, and cholesterol is crucial for preventing further progression of diabetic retinopathy.
- Monitoring and Follow-Up
- Regular check-ups are essential to monitor the condition and adjust treatment as necessary.
Understanding Ischaemic Retinopathy: The Wembley Stadium Analogy
The Eye as Wembley Stadium
Imagine your eye is like Wembley stadium, filled with fans (representing your retina) who can’t leave.
The Problem: Blocked Gates
In severe diabetic retinopathy or vein occlusion:
- Gates are blocked, preventing food from coming in and rubbish from going out
- This represents blocked blood vessels that normally:
- Bring in oxygenated blood to nourish the retina
- Remove waste products
The Consequences: Hungry Fans Cause Chaos
Without proper blood flow:
- Hungry fans (retinal cells) cause a ruckus
- They throw rubbish around (vitreous haemorrhage)
- Tear up seats and fight (retinal damage)
The Solution: Laser Treatment
Since we can’t unblock the gates:
- Laser treatment “wipes out” sections of fans
- This continues until remaining fans have enough food
- Treatment starts at the top of the stadium (cheap seats = peripheral retina)
- Repeated until enough fans are removed to calm the situation
The Result
- Remaining retina gets sufficient blood supply
- Stops producing vascular endothelial growth factor
- Prevents growth of new abnormal blood vessels (neovascularisation)
Important Note
The laser generally avoids the pitch (central retina):
- This is the most important part of the stadium
- In the eye, it’s responsible for detailed vision
Macular Oedema: A Waterlogged Pitch
- Macular oedema is like a waterlogged pitch in our stadium
- Laser treatment burns small bits of the pitch
- This helps to “dry out” the area (reduce the macular oedema)
Living with Diabetic Retinopathy
While diabetic retinopathy can be a challenging diagnosis, many patients maintain good vision with proper management. Here are some tips for living with this condition:
- Attend Regular Check-ups: Consistent monitoring is crucial for managing the condition effectively.
- Manage Your Diabetes: Keep blood sugar levels, blood pressure, and cholesterol under control.
- Adopt a Healthy Lifestyle: Regular exercise, a balanced diet, and quitting smoking can all contribute to better eye health.
- Use Visual Aids: If needed, various devices can help with daily tasks affected by vision changes.
Prevention of Diabetic Retinopathy
While not all cases of diabetic retinopathy can be prevented, certain measures can reduce your risk:
- Regular Eye Exams: Annual dilated eye exams are crucial for early detection and treatment.
- Control Blood Sugar Levels: Maintain good glycaemic control through diet, exercise, and medication as prescribed.
- Manage Blood Pressure and Cholesterol: Keep these within healthy ranges.
- Maintain a Healthy Weight: Obesity is linked to several risk factors for diabetic eye complications.
- Quit Smoking: This can significantly reduce your risk of diabetic retinopathy and other eye conditions.
