Macular degeneration, particularly in its wet form, poses a significant threat to vision in older adults, but anti-VEGF injections offer a hopeful solution. These eye injections inhibit harmful protein activity, improve vision, and prevent severe sight loss. By exploring the procedure, medication options, potential side effects, and alternative treatments, this article sheds light on managing this condition effectively.
Understanding Macular Degeneration Eye Injections
Macular degeneration is a common eye condition that can significantly affect vision, particularly in older adults. Among the most effective treatments for the wet form of this condition are anti-VEGF eye injections. These injections target and block the activity of the vascular endothelial growth factor (VEGF) protein, which is responsible for the abnormal growth of blood vessels and fluid leakage under the retina causing wet age-related macular degeneration (AMD). By administering these injections, ophthalmologists aim to stabilize or even improve vision and prevent severe vision loss that was common before the advent of such treatments.
The Procedure for Eye Injections
The injection process for macular degeneration involves a thorough preparation and a series of precise steps to ensure safety and effectiveness. Initially, patients undergo a diagnostic process that includes a dilated eye exam and optical coherence tomography imaging to assess the need for injections. Before administering the injection, the ophthalmologist uses numbing eye drops and cleans the eye with antiseptics to minimize infection risks and prepare for the painless injection. The actual injection, which takes only a few seconds, involves using a fine needle to deliver medication directly into the eye, with little to no discomfort for the patient.
Types of Anti-VEGF Medications
Several types of anti-VEGF medications are available, each with different durations and schedules. These include Lucentis, Eylea, Beovu, Vabysmo, and Avastin, with administration typically ranging from every four to twelve weeks depending on individual patient needs. Some medications, like brolucizumab (Beovu®), offer more extended intervals for injections, depending on how well the patient’s vision stabilizes.
Addressing Side Effects and Risks
After receiving anti-VEGF injections, patients may experience mild and temporary side effects such as soreness, blurry vision, or the sensation of floaters. These effects are usually manageable with over-the-counter pain relief and rest. More severe complications, though rare, can include inflammation, infection, or retinal detachment requiring immediate medical attention. Patients are encouraged to report any unusual symptoms to their healthcare provider promptly.
Alternative and Complementary Treatments
While anti-VEGF injections are the primary treatment for wet AMD, other options like photodynamic therapy (PDT) and laser photocoagulation are sometimes used, particularly in specific conditions like polypoidal choroidal vasculopathy. PDT involves using a light-sensitive drug, verteporfin, activated by a laser to break down unwanted blood vessels. This method may be combined with anti-VEGF treatments if necessary to manage vision loss more effectively.
Living with and Managing AMD
There are currently no medical treatments for dry AMD, but lifestyle changes including diet and taking AREDS2 supplements can help slow its progression. These adjustments should be discussed with a healthcare professional to tailor them to the patient’s needs offering potential benefits for eye health. Ongoing research seeks to find more effective solutions for both wet and dry forms of AMD.
