diabetic retinopathy treatment in Canada

Why early treatment matters

Diabetic retinopathy damages the small blood vessels of the retina, and by the time vision changes you notice, significant damage may already be present.

The disease runs from mild non-proliferative changes, through severe non-proliferative disease, to proliferative disease with fragile new vessels. Macular oedema, or fluid at the centre of the retina, can occur at any stage.

Screening and monitoring

Regular checks catch problems while they are still easy to treat.

Dilated eye examGuidelines generally recommend regular exams for everyone with diabetes. Your doctor sets the interval.
Retinal photographyDocuments changes over time.
OCT scanningDetects swelling that may not be visible to you.
PregnancyDiabetic eye disease can progress faster in pregnancy, so extra checks are usually advised.

Treatments with proven benefit

Which treatment you need depends on the stage and on whether the macula is affected.

Anti-VEGF injections

Reduce swelling and slow abnormal vessel growth. Usually a series of injections over time.

Laser photocoagulation

Treats leaking areas or the outer retina to reduce the drive for new vessel growth.

Steroid implants

Considered for some patients with persistent swelling.

Vitrectomy

Surgery to remove blood or scar tissue that is pulling on the retina.

What you can do every day

Everyday control protects your eyes alongside any treatment.

Keep blood sugar on target

Work with your care team on a plan you can maintain.

Control blood pressure and cholesterol

Both strongly affect retinal blood vessels.

Do not smoke

Smoking speeds up vessel damage.

Never skip appointments

Early treatment is far more effective than late treatment.

Frequently asked questions

Can diabetic retinopathy be cured?

Established damage cannot be undone, but treatment can slow or stop progression and protect the vision you have.

Does it hurt to have injections?

The eye is numbed first. Most people feel pressure rather than pain, and the procedure is quick.

Are experimental therapies an option?

Stem cell therapy is experimental, not approved in Canada, and does not replace the treatments above. We are glad to discuss it honestly during a consultation.
