Diabetic retinopathy

Diabetes can damage the retina silently. Regular screening protects your sight for the long term — in Fez, Morocco.

High blood sugar weakens the small vessels of the retina: they leak, become blocked, and can threaten vision. At first, everything happens without any symptom — hence the importance of annual screening.

What is diabetic retinopathy?

It is damage to the retina caused by diabetes. Silent for a long time, it can progress to swelling of the macula (edema) or bleeding. Caught in time, it is very well controlled ; neglected, it is a major cause of preventable vision loss.

Every person with diabetes should have their retina examined at least once a year, even without any visual problem. Early screening prevents serious complications.

Who should be extra vigilant?

Long-standing diabetes (several years)
Poorly controlled diabetes (high HbA1c)
Associated high blood pressure
High cholesterol
Pregnancy in a woman with diabetes

Screening

Dilated fundus exam

Examines the whole retina for lesions.

Macular OCT

Detects macular edema to the micron.

Retinal photography

Maps and tracks changes over time.

Management

The foundation remainscontrolling diabetes and blood pressure. Depending on the stage: retinal laser, intravitreal injections in case of edema, and surgery for advanced forms. Regular follow-up is essential.

Frequently asked questions

I have diabetes but I see well — should I get checked?

Yes. Retinopathy begins without symptoms : good vision does not mean a healthy retina. Annual screening remains essential.

Can lost vision be recovered?

Treatments mainly aim to stop the worsening. Recovery depends on the stage: hence the value of acting early.

Does the laser hurt?

It is performed under anesthetic drops and is well tolerated, in short sessions at the practice.
