Understanding Eylea Injections: A Comprehensive Guide for Patients

What is Eylea and How Does It Work?

Eylea (aflibercept) is an injection used to treat a variety of eye conditions, primarily those affecting the retina. Conditions like age-related macular degeneration (AMD), diabetic macular edema (DME), and retinal vein occlusion (RVO) can lead to vision loss if left untreated. Eylea works by inhibiting a protein called VEGF, which is responsible for abnormal blood vessel growth and fluid leakage in the retina. By blocking VEGF, Eylea reduces swelling and prevents further damage to the retina, helping to preserve or improve vision.

What to Expect During the Procedure

Patients may feel apprehensive about receiving an injection in the eye, but the procedure is typically straightforward and quick. First, the eye is numbed with drops or a gel to minimize discomfort. An antiseptic solution is then applied to prevent infection, followed by the actual injection, which takes only seconds. Most patients feel little to no pain, though some may experience mild pressure. Your doctor will guide you through aftercare steps, which often include avoiding strenuous activity for a few days and using prescribed eye drops if necessary.

Frequency and Treatment Plans

Treatment plans with Eylea vary based on individual conditions. Initially, patients often receive monthly injections, but as the treatment progresses, frequency may decrease to every two months. After a year, some patients may only need injections quarterly or as needed based on their response to treatment. Your ophthalmologist will closely monitor your progress through regular check-ups and imaging scans to determine the best treatment schedule.

Side Effects and Risks to Consider

While Eylea is generally safe, like all medical treatments, it carries potential side effects. Common side effects include temporary eye redness, discomfort, and floaters. Serious risks, though rare, include eye infections, increased intraocular pressure, and retinal detachment. Immediate symptoms like sudden pain, loss of vision, or flashes of light should be reported to your doctor without delay.
