Diabetes affects small blood vessels throughout the body — including those in the retina. Diabetic retinopathy can progress quietly, which is why routine screening is recommended even when your vision seems fine.
What does the eye check involve?
Drops are used to widen (dilate) your pupils so the doctor can examine the retina. Depending on findings, an OCT scan or retinal photographs may be taken to look for swelling or leaking vessels.
Who is at higher risk?
- People who have had diabetes for many years
- Those with high HbA1c, blood pressure or cholesterol
- People with kidney disease
- Women with diabetes who are pregnant
Treatment is more effective when started early
Options such as intravitreal injections, retinal laser and, in advanced cases, vitrectomy aim to reduce the risk of serious vision loss. Good control of sugar, blood pressure and cholesterol also matters.
If you have diabetes, ask your eye specialist how often you should be screened — and mark it on your calendar.
Frequently asked questions
