Retinal examination
We examine the entire visible retina for typical vascular changes and findings that need treatment.
Recognize retinal changes before vision decreases
Diabetic eye examination
Diabetes can damage small retinal vessels long before vision changes are noticed. Regular examinations help detect problems early and plan follow-up or treatment in good time.
Understanding the procedure
Good vision does not necessarily mean a healthy retina.
Diabetic retinopathy may initially cause no symptoms. With dilated pupils, we can identify microaneurysms, bleeding, deposits, poor circulation and new vessel growth.
OCT adds information when the macula may be affected. Photography and widefield imaging support documentation and monitoring. Angiography is needed only for specific questions.

Used where needed
Which examinations might be included?
Not every appointment requires all devices.
Retinal photography
Images record bleeding, vascular changes and other findings so we can compare them at later visits.
OCT of the macula
The cross-sectional image reveals fluid or swelling in the centre of the retina, even when it is difficult to see during examination.
Fluorescein angiography
In selected cases, it shows areas without blood flow, leaking vessels and abnormal new blood vessels.
Step by step
What happens at a diabetic eye check
Bring your diabetes record, medication list and any previous examination results.
Tracking changes over time
We consider how long you have had diabetes, current metabolic control, blood pressure, kidney disease, pregnancy and previous eye findings.
Check visual function
Visual acuity and, if needed, your glasses prescription show whether visual function has changed.
Dilating the pupils
After pupil drops, we examine the retina, including the macula and peripheral areas.
Set risk and interval
Your examination findings, type of diabetes and overall risk determine when you need another check or a referral for treatment.
Understanding the results
Eye care and general medical care work together.
Eye checks can detect retinal damage and allow treatment, but they cannot replace good control of blood sugar, blood pressure and other risk factors. Care from your GP or diabetes specialist remains essential.
Sudden vision loss, new black spots, shadows or distorted vision need prompt assessment, regardless of your next scheduled check-up.
Well prepared
How to prepare for your visit
- Diabetes pass or current HbA1c information
- List of medicines
- Sunglasses for the return journey
- Do not drive if your pupils are dilated
Frequently asked questions
Clear, concise answers.
How often do I need an eye examination?
The interval depends on your type of diabetes, previous retinal findings, metabolic control and particular risks. After the examination, we tell you when to return.
Why are the pupils dilated?
This allows a thorough, three-dimensional assessment of the retina. Your vision may be blurred and sensitive to light for several hours afterwards.
Can retinopathy be treated?
Yes. Depending on the stage, options include closer monitoring, retinal laser treatment, intravitreal medicine or surgery. Good general medical control remains important.
