In case you are experiencing any of the symptoms noted above, it’s essential to book an appointment together with your diabetes healthcare team immediately. They’ll do an intensive eye examination and certain refer you to a watch specialist (ophthalmologist) for further tests.
The primary test is an examination of your eye with a tool called an ophthalmoscope. It allows your doctor to have a look at the back of your eye. This a part of your eye is known as the fundus, and consists of the retina, macula, optic disc and blood vessels.
If the ophthalmologist sees abnormalities during examination with an ophthalmoscope, they are going to likely order a test called optical coherence tomography. This test uses light waves to take cross-section pictures of your retina. The ophthalmologist can then review and analyze these pictures and determine if you’ve DME.
How is diabetic macular edema treated?
There’s currently no cure for DME. Nonetheless, optimal diabetes management and medications may also help slow its progression and limit the quantity of vision damage chances are you’ll suffer.
When you’ve DME, your body makes an excessive amount of of a protein called vascular endothelial growth factor (VEGF). This causes blood vessels to grow too quickly, so that they’re weak and leak blood and fluid into your retina and macula. Anti-VEGF medications block the protein to assist stabilize your blood vessels and forestall recent ones from growing, which stops the leakage of fluid.
The anti-VEGF medicines utilized in Canada to treat DME are:
- Aflibercept (Eylea®)
- Bevacizumab (Avastin®)
- Ranibizumab (Lucentis®)
These medications are given by injection. Chances are you’ll be given an injection once a month for the primary 3 to six months of treatment. After that, fewer injections are needed.
One other injectable medication was recently approved by Health Canada for individuals with DME. Faricimab (Vabysmo®) is a drug that targets each VEGF and angiopoietin-2, one other protein that may construct up within the eyes and contribute to DME. It is usually administered by injection, but at less frequent intervals.
Along with anti-VEGF medications, steroid injections, special eye drops that contain NSAIDs (non-steroidal anti-inflammatory drugs) and laser therapy are also used to treat DME.
