Diabetic macula oedema may be detected during your annual eye screening visits, which are offered to all patients with diabetes. Digital photographs of your retina may show signs of early diabetic macular oedema. You may not notice any changes in your vision at this stage.
If diabetic macular oedema is detected, you will be referred to the medical retina clinic at Moorfields for further assessment. If you are attending clinics at Moorfields, you do not need to attend your local diabetes eye screening programme. If you do not require treatment or when your treatment is complete, you will be discharged from Moorfields. After being discharged, it is important to resume attending your annual local diabetes eye screening appointments.
In the early stages of diabetic macular oedema, no treatment is needed.
If treatment is required, the treatments for diabetic macular oedema are:
A laser is used to produce small burns on areas of leaking blood vessels in the macula. Usually, laser burns are applied over several sessions. The goal of laser therapy is to reduce the amount of fluid in the macula. Several sessions may be required to achieve this. The full effects of laser therapy only occur after several months. This is why you may be asked to return to clinic three or four months after laser therapy. Studies have shown that laser therapy reduces the risk of visual loss by 50%. The aim of laser therapy is to stabilise your vision. Improvement in vision only happens in a small number of cases.
This treatment involves the injection of medication into the eye. The drug works by reducing fluid leakage from blood vessels around the macula. This in turn reduces swelling of the macula. Studies have shown that this treatment is effective in preventing visual loss and can improve vision in some patients. A course of injections is required to treat diabetic macular oedema. At the start of treatment, usually one injection per month is needed. It is important to attend all appointments while receiving injection therapy. This treatment will not work if you do not have the injection at a regular interval. The length of time between injections, and how long you will need to stay on injection therapy will depend on how you respond to the treatment.
This includes an initial consultation and a visual acuity assessment.
If further outpatient tests and investigations are required, they will be charged at an additional rate. The most commonly required test is an OCT scan. Your consultant will discuss this with you at your consultation.
The cost of onward treatment will be provided after initial consultation, based on your personalised treatment plan.
Anti-VEGF injections are a common treatment for medical retinal conditions. We offer a 10% discount if you pay for a course of three injections.
