More than one million Australians have diabetes. Many are unaware they have it as the onset is subtle. - Your optometrist may be able to detect signs of previously undiagnosed diabetes
- Diabetes can cause changes to the blood vessels in the retina at the back of the eye, leading to a lack of oxygen which can cause significant disruption to vision
- Early diagnosis is essential to help prevent loss of vision
The risk of developing it increases with time and through poor control of blood sugar levels. There are two types: - Background retinopathy rarely causes vision loss and generally does not require treatment. Occasionally, it may cause vision to be hazy and distorted
- Proliferative retinopathy is more serious and requires prompt treatment to prevent vision loss
- An ophthalmoscope to view the retina at the back of the eye
- Photographing the interior of the eyes
- Early stages - may cause a blur in central or peripheral vision
- Moderate stages - may cause hazy vision, blind spots or floaters. These symptoms are associated with light prevented from reaching the retina
- Advanced stages - scar tissue may form because of blood vessel growth, causing additional distortion, blur, and risk of loss of sight
Actions to help prevent diabetic retinopathy include: - Taking prescribed medication
- Not smoking
- Adhering to a low GI diet
- Exercising regularly
- Laser or other surgical treatment may be used to reduce the progression of disease
- Optical aids such as magnifying glasses or telescopic lenses may be helpful where vision loss has occurred
Your optometrist will: - Check many factors that may be affected by diabetes
- Help address vision problems
- Provide information about the management of diabetic vision issues
Regular visits help with early detection and treatment. |
