Did you know that Diabetes is one of the most common causes of sight loss amongst people of working age? With 1 in 25 people in the UK suffering from diabetes we want to highlight the importance of regular eye exams. Here we look at how diabetes can affect your vision and what your optometrist can do to help monitor and maintain your diabetes.
How can diabetes affect my vision?
It is possible that your diabetes won’t cause any changes to your vision. However, diabetes can affect your eyes in several ways:
- Changes in blood sugar levels caused by diabetes can affect the lens inside your eye – especially when your diabetes isn’t controlled. These changes can result in your vision blurring.
- Diabetes can lead to cataracts – where the lens in your eye becomes cloudy. This happens because the high sugar levels found in the fluid around the lens to swell with more water than usual. The lens then focuses light differently on the retina at the back of the eye, and this may cause your spectacle prescription to change as the cataract develops.
- Some people with diabetes develop glaucoma, an eye condition that cause damage to the optic nerve. This is often because of raised pressure inside the eye.
- They are also at more of a risk of developing Macular Oedema (leaks between the layers of the retina) and should be advised to contact their optometrist if the note any distorted vision ASAP.
- When diabetes affects the network of blood vessels supplying the retina at the back of the eye, this is called diabetic retinopathy. Diabetes can cause the blood vessels to become blocked, to leak or to grow incorrectly, which can eventually lead to blindness.
Why are regular eye examinations and screening tests so important?
If your diabetes is well controlled, you’re less likely to have problems, or they may be less serious. Regular eye exams can help spot the early signs of the condition and enable you to act to control diabetes before it damages your body and your eyes.
Optometrists can pick up retinal changes using Volk, Ophthalmoscopy, Fundus Photography and OCT Scans and can advise patients on the need for intervention before they have a real problem.
Many diabetic patient’s attend the Diabetic Clinic at their hospital for Diabetic Retinopathy Screenings and assume that they therefore do not need to come for their eye examination, however not all of them are in fact having a full-service eye examination and they should still attend the optometrist for further tests.
