Why diabetes makes regular retinal checks important

Diabetes can affect the small blood vessels of the retina, the light-sensitive tissue at the back of the eye. Early diabetic retinal changes may not cause noticeable symptoms, which is why regular dilated eye examinations are important even when vision appears normal.

Why Retinal Examinations Matter

A retinal examination can help identify diabetes-related changes before they begin to affect daily vision. Finding changes earlier may allow closer monitoring, medical coordination or eye treatment when required.

What Happens During a Diabetic Eye Examination?

The visit may include vision assessment, eye-pressure measurement, dilating drops, examination of the retina, and retinal photographs or OCT imaging when clinically indicated.

The ophthalmologist may also ask about the duration and type of diabetes, recent glucose control, blood pressure, kidney health, pregnancy and previous eye treatment.

How Often Should the Eyes Be Examined?

Many people with diabetes are advised to have a dilated eye examination at least once a year. The recommended interval may be shorter or longer depending on previous retinal findings, treatment history and the ophthalmologist's advice. Do not wait for blurred vision before arranging the examination.

What to Bring

Bring previous retinal reports or scans, a list of current medicines, details of any eye injections, laser or surgery, recent diabetes and blood-pressure information when available, and current spectacles. Because dilating drops can temporarily blur near vision and increase light sensitivity, ask the centre whether you may need someone to accompany you.

Symptoms That Need Prompt Attention

Seek prompt assessment for sudden reduction in vision, a new shower of floaters, flashes of light, a curtain-like shadow, sudden distortion or a dark area in vision, or significant eye pain or redness.

Living with diabetes?

Request a diabetic retinal examination even when your vision currently feels normal.
