Diabetic eye disease is a fairly common complication of diabetes that occurs when high blood sugar levels cause damage to the retina which is the part of the eye responsible for transmitting what we see to our brains. Over time, this damage could become so significant that it begins to compromise your eyesight. Left untreated, it can lead to blindness.

Types of diabetic eye disease

One of the biggest misconceptions about diabetic eye disease is that it is just one condition. However, there are actually several different ocular conditions that affect patients with diabetes and that can occur as a result of poor management of the condition. These include:


Diabetic retinopathy. This affects the blood vessels in the retina and is the most common cause of vision loss among diabetic patients.


Diabetic macular edema. This occurs as a consequence of diabetic retinopathy and is characterized by swelling in a part of the retina called the macula.


Cataracts. This condition is characterized by the clouding of the natural lens of the eye.


Glaucoma. Diabetes nearly doubles the risk of developing glaucoma which occurs when there is damage to the optic nerve, usually as a result of accumulated pressure in the eye.

Am I at risk of developing diabetic eye disease?

Diabetic eye disease can affect all patients with diabetes, regardless of whether they have been diagnosed with Type 1 or Type 2. The risk also increases in line with how long you have been diagnosed with diabetes, and approximately 45% of Americans diagnosed with the condition have developed some degree of diabetic eye disease. 


You are also at greater risk of being affected by diabetic eye disease if you:


-         Have high blood pressure

-         Have high cholesterol

-         Are pregnant

-         Are of Asian or Afro-Caribbean descent

Symptoms of diabetic eye disease

Unfortunately, it is fairly difficult to diagnose diabetic eye disease until it is more advanced since symptoms often don’t become apparent until the later stages of the conditions. For this reason, the vast majority of cases of diabetic eye disease are detected by opticians during routine screening examinations. However, if you start to experience any of the following and are diabetic, we strongly recommend that you speak to our doctor and/or optician as soon as possible:


-         Sudden vision loss

-         Gradually worsening vision

-         Floating shapes in your field of vision

-         Blurred or patchy vision

-         Eye pain

-         Redness


You may not have diabetic eye disease, but it is important to get your symptoms checked out promptly, rather than waiting until your next diabetic eye screening appointment.

Is there any way of preventing diabetic eye disease?

Although diabetic eye disease is a considerable threat, it is by no means a certainty and you can significantly reduce the risk of it developing. The most effective ways of doing this include:


-         Taking responsibility for your health. This means controlling your blood sugar levels and not letting them regularly dip too high or low.


-         Keeping your blood pressure under control and managing your stress levels so that you can do this.


-         Controlling your cholesterol and keeping it within healthy limits.


-         Attending regular eye exams where our optician will perform diabetic eye screening to check that diabetic retinopathy isn’t developing.
