Diabetic macular edema (DME) is a severe eye disease affecting patients with diabetes. Your doctor may recommend Vabysmo or Eylea for DME. Both drugs are effective, but there are significant differences between them. This guide helps you understand which treatment is better suited to you.
What Is Diabetic Macular Edema?
Diabetic macular edema (DME) develops when the macula becomes swollen due to fluid accumulation. The macula is the central aspect of the retina. High blood glucose levels may damage the blood vessels in the eye. This results in fluid leaking into the macula, causing blurred vision or potential vision loss.
Understanding Vabysmo And Eylea
-
What Is Vabysmo?
The brand name for faricimab, Vabysmo, is an FDA-approved prescription injection for the treatment of DME. Vabysmo uses a dual-pathway model that blocks both VEGF-A and Angiopoietin-2 (Ang-2), helping mitigate the formation of abnormal blood vessels.
-
What Is Eylea?
Eylea is the brand name for aflibercept, an FDA-approved prescription injection for the treatment of DME. Eylea primarily works by blocking VEGF-A and placental growth factor (PlGF) with a regular dose of 2mg per injection.
-
What Is Eylea HD?
Eylea HD is an enhanced strength version of Eylea, containing 8mg of aflibercept rather than 2mg. Eylea HD received FDA approval for DME in 2023 and may allow longer treatment intervals than standard Eylea.
How do The Medications Work?
-
Vabysmo Mechanism
Vabysmo works by targeting two different pathways in your eye. It inhibits VEGF-A, thereby preventing abnormal blood vessel growth. Vabysmo also inhibits Ang-2, which promotes blood vessel stability and might improve overall fluid control. The theory with the dual pathway is that it might enhance fluid control.
-
Eylea Mechanism
Eylea works by inhibiting VEGF. It binds to VEGF-A and PlGF, reducing fluid leakage from blood vessels. Normal Eylea and Eylea HD have the exact mechanism of action and both inhibit VEGF.
-
Vabysmo Dosing
Vabysmo offers flexibility in its dosing schedule. First option, four monthly loading doses. Then the doctor will assess your response, and it may involve an injection every 8, 12, or 16 weeks.
Second option: six-monthly loading doses. After that, you will get injections every 8 weeks, but some people will need them monthly.
-
Eylea Dosing
Normal Eylea requires more frequent injections — about every 8 weeks — and you may need it every 4 weeks, depending on your provider’s assessment.
-
Eylea Hd Dosing
Eylea HD has longer intervals. You will get three loading doses once a month, and then receive injections every 8 or 16 weeks. Most patients will ultimately progress to the vision-restoring phase at the extended interval.
Effectiveness Comparison
-
Vision Improvement
Both medications will enhance vision in patients with any stage of DME. Therefore, there don’t seem to be differences in vision-acuity gain across medication types. Eylea HD demonstrated non-inferiority to Eylea. In addition, when comparing Vabysmo with Eylea and Eylea HD, visual acuity levels were similar.
-
Reduction Of Retinal Thickness
Vabysmo has demonstrated improved outcomes for reducing central subfield thickness (CST). A recent paramount study in 2024 demonstrated specific results through a systematic review and meta-analysis. When evaluating CST and medication efficacy, Vabysmo led to a 19 μm reduction in CST, more than Eylea and Eylea HD combined.
This means Vabysmo ‘dries’ the retina better (as in Vabysmo ‘dries’ the retina). The data have been highlighted in the presentation of results at 12 weeks in the clinical trials. Many will enjoy an enhanced drying effect, which may be beneficial for some.
-
Duration Of Treatment
Vabysmo has the longest dosing intervals. You will receive some injections up to 16 weeks. Eylea HD also has up to 16-week intervals. Eylea at the standard frequency usually requires an injection every 8 weeks. Less frequent injections with the doctor will increase the overall quality of life. To deepen our understanding of patient treatment timelines, knowing how quickly Eylea works may help.
Side Effects
-
Common Side Effects
Both drugs have similar side effect profiles. Common side effects of Vabysmo include blood in the white of the eye and cataracts. You may also experience eye floaters or blurred vision. Common side effects of Eylea HD include cataract, conjunctival hemorrhage, and increased eye pressure. Eye discomfort and vitreous floaters are also common.
-
Serious Side Effects
Serious side effects are rare but possible. These include eye infections (endophthalmitis). Retinal detachment may occur in some cases. Both drugs can increase your risk of stroke or heart attack.
Contact your doctor immediately if you experience eye pain, redness, or vision changes. Light sensitivity is another warning sign.
-
Cost Factors
The cost of treatment will vary depending on the medications used and the duration of treatment. Cost will also depend on the number of injections per year.
The cost of medication should be lower with Vabysmo due to extended dosing. While Vabysmo may be used over a longer time frame, the cost of treatment over time will likely be lower due to fewer visits. Insurance availability will also vary by the insurance plan. Talk to your insurance provider about specific costs.
Choosing A Treatment
-
Factors To Consider
Many factors influence what treatment option is right for you! One consideration is the severity of your disease. Your response to prior medications can also affect the treatment recommended.
Your injection scheduling preference is another consideration. Some patients prefer fewer visits/injections, while others prefer a treatment option with more long-term clinical evidence.
-
Practice Recommendation
Your eye doctor will consider your unique circumstance. Your personal medical history also affects your treatment recommendation. Keep in mind your current vision situation!
From there, the doctor will examine how your condition responds to treatment and, if needed, modify your dosing regimen.
-
Insurance Implications
Insurance coverage is key to accessibility! Eylea has broader insurance coverage because it has been on the market longer than Vabysmo. Vabysmo coverage is expanding as it becomes available at more providers’ practices. Before making any decisions, contact your insurance formulary to see what is covered.
Monitoring And Follow-Ups
-
Routine Eye Exams
You will be required to have routine monitoring with both treatments. Your doctor will be using optical coherence tomography (OCT) scans to measure the thickness of your retina. Don’t forget! Visual acuity tests will be performed frequently to measure improvement in your vision. Your doctor will also measure your eye pressure after each injection.
-
Adjusting Treatment
Your treatment plan could change over time. If your doctor believes you are responding well to the treatment, they may increase the time between injections. Even if the doctor may feel you are responding well, you may need more frequent injections.
It is always important to keep evaluating and continue to try to get the best results from your treatment. It will be essential to be open and honest with your doctor about your vision as well.
Take Control Of Your Vision Today
Both Vabysmo and Eylea are suitable treatments for DME. Vabysmo, using dual-pathway inhibition, can be used for longer intervals between injections. Vabysmo has shown a greater reduction in retinal thickness than Eylea. Eylea HD, a higher concentration of Eylea, provides longer-lasting results than injections and is a standard of care for evidence of clinical safety and effectiveness.
The best treatment option will depend on your condition. Retinopathy severity tendencies, injection frequency, and insurance coverage of benefits are to be weighed. Both treatments were considered adequate at holding your vision if initiated early.
