Diabetic Retinopathy

The frequency depends on your type of diabetes, how long you have had it, and whether diabetic retinopathy is already present. In the absence of retinal involvement, an examination at least once a year is generally recommended. If retinopathy is already present, or in the case of pregnancy in a diabetic patient, the schedule may be shortened to every 3 to 6 months. Your ophthalmologist will determine the appropriate frequency based on fundus photographs, OCT findings, and your glycemic control (HbA1c).

Yes, well-controlled diabetes significantly reduces the risk of diabetic retinopathy but does not eliminate it entirely, especially when the disease has been present for a long time. Past hyperglycemia may have already weakened the retinal capillaries. This is why screening remains essential, even with good HbA1c levels, in order to detect early lesions that have not yet caused visual symptoms and to intervene at the right time if necessary.

No, diabetic retinopathy is generally painless. This is in fact one of its pitfalls: the eye does not hurt, it is not red, and vision can remain good for a long time even though the retinal blood vessels are already being damaged. Pain only occurs in certain advanced complications (for example, neovascular glaucoma), which underscores the importance of not waiting for pain or significant vision loss before seeking regular examinations.

Driving depends primarily on your visual acuity and visual field, not solely on the diagnosis of diabetic retinopathy. Many patients can continue to drive normally, sometimes with appropriate corrective lenses, as long as the legal vision requirements are met. However, in cases of significant macular edema, vitreous hemorrhage, or marked vision loss, driving may become dangerous. Your ophthalmologist can provide specific guidance and, if needed, recommend a temporary or permanent driving restriction depending on the situation.

A diagnosis of diabetic retinopathy is a signal to strengthen everything that protects your eyes in the long term. This includes: better glycemic control (in coordination with your diabetologist), managing blood pressure and cholesterol, quitting smoking, engaging in appropriate physical activity, and maintaining a balanced diet. Regarding vision, it may be helpful to optimize your eyeglass prescription, improve lighting (for reading, cooking, and working), and adapt certain daily tasks if vision loss is present. These measures complement any ocular treatments (laser, intravitreal injections, vitrectomy).

In most cases, yes. Intravitreal injections and retinal laser treatment are usually compatible with other systemic treatments (insulin, oral antidiabetic medications, antihypertensives, anticoagulants). You should never stop a cardiac or anticoagulant medication on your own without medical advice. Always inform your ophthalmologist of your complete medication list and medical history (cardiac, vascular, surgical) so that appropriate precautions can be taken, in coordination with your general practitioner or diabetologist if needed.

The lesions associated with diabetic retinopathy are often chronic: the goal is stabilization rather than complete cure. However, with proper treatment (diabetes control, intravitreal injections, laser, and possibly vitrectomy), it is possible in many cases to preserve vision over the long term and prevent severe forms (vitreous hemorrhage, tractional retinal detachment, neovascular glaucoma). The objective is therefore to slow or halt disease progression rather than to completely eliminate all traces of the condition, which is why regular follow-up remains important even when vision is considered stable.
