Diabetic Retinopathy

When blood sugar stays high for a long time, it does damage throughout the body - the kidneys, the nerves, the heart. The eyes are affected in the same way, as high blood sugar can damage the delicate blood vessels of the retina. Inside your eye, at the very back, lies a thin layer of tissue called the retina. It works like a film in a camera, capturing light and sending visual signals to your brain. The retina is richly supplied with tiny blood vessels, and high glucose levels slowly injure those vessels. They leak. They swell. Eventually, the body tries to grow new vessels to compensate - but those new vessels are fragile and disorganized, and they cause more harm than good. This is diabetic retinopathy.

Your risk is meaningfully higher if any of the following apply to you:

• You have had diabetes for more than five years
• Your blood sugar has been consistently difficult to control
• You also have high blood pressure - extremely common among our patients here
• You are pregnant and have diabetes
• You smoke

In the early stages, your vision may seem completely normal. This is what makes diabetic retinopathy so dangerous - by the time you notice something, the disease has already progressed significantly.

As it advances, the symptoms to watch for include:

• Blurred or distorted vision that comes and goes
• Dark spots or cobweb-like floaters drifting across your field of vision
• Difficulty seeing clearly in dim light or at night
• Colours that appear washed out or faded
• Straight lines that look wavy or bent

These symptoms mean you need to see an eye specialist soon - within days, not weeks. But some situations require you to go the same day:

• Sudden loss of vision in one or both eyes
• A dramatic change in vision that comes on rapidly
• Flashes of light that persist
• Severe eye pain

Do not delay seeking medical attention, as these symptoms may indicate serious eye complications that require urgent assessment.

It is essential to know about the various stages of diabetic retinopathy:

• 1. Mild NPDR
  Tiny microaneurysms form in retinal vessels. No symptoms yet. Manage blood sugar, pressure, and cholesterol.
• 2. Moderate NPDR
  Blood vessels begin blocking. Cotton wool spots and small bleeds appear. Risk of Diabetic Macular Edema (DME) causing blurred vision.
• 3. Severe NPDR
  Many vessels blocked; retina signals new vessel growth. Blurring or dark spots may appear. Close monitoring is essential.
• 4. Proliferative DR (PDR)
  Fragile new vessels burst, causing floaters, sudden vision loss, or retinal detachment. This is an emergency requiring immediate treatment to prevent blindness.

When a patient with diabetes comes to our hospital concerned about their eyes, we start with a dilated eye examination - drops that widen the pupil so we can properly examine the retina. It is painless and takes only a few minutes, but it tells us a great deal.

In more complex cases, we use additional investigations:

• Fluorescein angiography
  a dye injected into a vein that highlights the blood vessels in the retina, showing us exactly where leakage is occurring
• Optical coherence tomography (OCT)
  detailed cross-sectional images of the retina that detect swelling not visible to the naked eye

Depending on the stage of your disease, your doctor may recommend:

• Laser therapy
  to seal leaking blood vessels and stabilize the retina
• Anti-VEGF injections
  medication given directly into the eye under local anaesthesia to reduce swelling and stop abnormal vessel growth; this has transformed outcomes for many patients with advanced disease
• Vitrectomy
  surgery to remove blood or scar tissue from inside the eye, used in the most severe cases involving bleeding or retinal detachment

Controlling your blood sugar is the single most powerful thing you can do to protect your eyes. Here is what good long-term eye protection looks like in practice:

• Regular eye examinations as advised by your ophthalmologist, typically at least once a year for most people with diabetes, even when you feel fine, and your vision seems normal.
• Know your numbers
  keep track of your blood sugar, blood pressure, and cholesterol. All three affect your eyes
• Eat to support your glucose control
  a diet built around vegetables, legumes, whole grains, and lean protein makes a real difference over time
• Move regularly
  even brisk walking most days of the week improves blood sugar management
• Stop smoking
  if you smoke, this is one of the most impactful changes you can make for your eyes, your heart, and your kidneys all at once
