Diabetic Eye Disease

Diabetic Eye Disease

Diabetes is a serious disease that if not controlled, can cause damage to most of the organs in your body. One third of diabetics have diabetic eye complications. Of these patients, 5% eventually go blind. This is mainly due to missed diagnosis.

It is therefore extremely important to have your eyes checked by an ophthalmologist when you are diagnosed with diabetes. Yearly consultations are usually required to detect problems early so that vision can be preserved.

OCT or optical coherence tomography scans are imperative in managing diabetic patients. A fluorescein angiogram is also done if retina complications are suspected. Patients with diabetes often develop cataracts sooner than other patients.

What is diabetic eye disease?

Diabetic eye disease is a term used to describe a group of eye diseases that affect people with diabetes. Diabetes affects your eyes when your blood sugar is too high. Several eye problems that can all result from diabetes include the following:

  • Diabetic retinopathy – this condition is caused by damage to the blood vessels of retina. As the condition progresses, you are likely to develop mild vision problems which can eventually lead to blindness.
  • Diabetic macular edema – this is the build-up of fluid in the centre of your retina called the macula. The build-up of this fluid causes the macula to swell which then distorts your vision.
  • Cataracts – these are the clouding of the lens of your eye. Clouded vision caused by this condition makes it difficult to perform activities such as reading or driving.
  • Glaucoma – this is a group of conditions that damage your optic nerve. The health of your optic nerve is imperative for good vision. Glaucoma is often caused by abnormally high pressure in your eye.

Symptoms of diabetic eye disease

At Kloof Eye, we care about the health of your eyes. Diabetic eye diseases often present with no early symptoms such as pain or changes in your vision. This is especially the case with diabetic retinopathy. We encourage you to visit our eye doctor should you experience any or all of the following symptoms:

  • Poor or low quality colour vision
  • Floaters or dark spots across your vision field
  • Flashes of light
  • Dark areas in your field of vision or vision loss
  • Blurry or wavy vision
  • Day-to-day changes in your vision

What are the risk factors?

  • High cholesterol – can increase the risk of developing a diabetic eye disease.
  • High blood pressure – damages blood vessels thus increases your chances of developing a diabetic eye disease.
  • Tobacco use – can contribute to high blood pressure as well as high blood lipid levels.
  • The duration of your diabetes – having diabetes for a long time puts you at a higher risk of getting a diabetic eye disease.
  • Poor blood sugar level control – consistently high blood sugar can increase the risk of developing a diabetic eye disease.

Diabetic eye disease treatment

Manage your diabetes by controlling your blood pressure, blood glucose and cholesterol along with quitting smoking. This can go a long way in preventing serious diabetic eye diseases.Advanced eye problems caused by diabetes can be treated by your doctor either with medicines, surgery, or laser treatments.

  • Medicine: Your eyes can be treated with anti-VEGF medicine. These treatments reduce new blood vessel growth and are used to treat a number of eye conditions such as diabetic macular edema. These treatments help improve vision or stop vision loss.
  • Laser treatment: This is also known as photocoagulation and treats leaky blood vessels and extra fluid. This treatment can prevent eye diseases from progressing or getting worse.
  • Vitrectomy: This is a surgery performed by ophthalmologists to remove the vitreous gel. This is the clear gel that fills the centre of your eye.
  • Cataract surgery: This involves removing the cloudy lens of your eye and replacing it with an artificial lens.

Diabetic Eye Disease FAQ

  • You should seek a specialist evaluation if over-the-counter drops no longer provide relief or if your vision is becoming frequently blurred. Chronic inflammation from untreated Dry Eye can damage the corneal surface; our team at Kloof Eye uses advanced diagnostic tools to create a customised management plan for you.

  • Excessive tearing is often a reflex response to the irritation caused by an underlying lack of quality, lubricating tears. When the eye surface becomes too dry, the brain signals for an emergency flood of “watery” tears, which lack the necessary oils to stay on the eye, leading to a cycle of dryness and tearing.

  • Yes, Omega-3 fatty acid supplements are clinically proven to improve the quality of the oil layer in your tears and reduce ocular inflammation. We often recommend specific pharmaceutical-grade supplements as part of a holistic treatment plan to support your long-term eye health in the dry Pretoria environment.

  • Punctal plugs are tiny, biocompatible inserts placed in the tear ducts to block drainage and keep your natural tears on the eye longer. This quick, painless “in-chair” procedure at our Erasmuskloof rooms can be temporary (dissolvable) or long-lasting (silicone), depending on the severity of your symptoms.

  • Blue light filters do not treat Dry Eye, but reducing screen glare and following the “20-20-20 rule” can significantly decrease digital eye strain. Because we blink 60% less when looking at screens, patients in the Constantia Park and Waterkloof areas often find that scheduled “blink breaks” help maintain a healthy tear layer during the workday.

  • MGD is a condition where the oil-producing glands in your eyelids become blocked, causing your tears to evaporate too quickly. This is the leading cause of “Evaporative Dry Eye”; we use specialised diagnostic imaging in Pretoria East to check these glands and recommend targeted treatments like warm compresses or clinical lid expressions.

  • While there is no permanent “cure” for chronic Dry Eye, modern treatments can provide long-term relief and reduce your dependence on daily drops. By identifying the root cause—such as Meibomian Gland Dysfunction (MGD)—our specialists at Kloof Eye can implement advanced therapies that restore your natural tear film balance.

  • Dry Eye Syndrome occurs when your eyes don’t produce enough quality tears, often exacerbated by Pretoria’s dry Highveld climate and air conditioning. At our Erasmuskloof practice, we treat patients whose symptoms are worsened by the low humidity and dust common in the Gauteng region, leading to persistent grittiness, redness, and blurred vision.
