Wet age-related macular degeneration (AMD) is a progressive eye condition affecting millions worldwide, particularly those over 50. It’s characterized by the growth of abnormal blood vessels beneath the retina, leading to rapid vision loss if left untreated. Fortunately, advancements in medical science offer effective treatments to manage this condition and preserve vision. One such treatment is injections, which have revolutionized the management of wet AMD. In this comprehensive guide, we delve into what to expect from wet AMD injections, empowering you with the knowledge needed to navigate your treatment journey with confidence.

Before delving into injections, let’s explore wet AMD in more detail. AMD is a chronic eye disease causing deterioration of the macula, the central part of the retina responsible for sharp, central vision. The macula is essential for activities such as reading, driving, and recognizing faces. In wet AMD, abnormal blood vessels grow beneath the retina, a process known as choroidal neovascularization (CNV). These vessels leak fluid and blood, leading to retinal damage and rapid vision loss. Factors such as aging, genetics, smoking, and hypertension contribute to the development of wet AMD.

Apart from AMD, several other ocular conditions may require injections into the eye for management, including diabetic retinopathy, retinal vein occlusion, and macular edema. These conditions share a common pathophysiology involving abnormal blood vessel growth or fluid accumulation in the retina. Injection therapy, often employing anti-vascular endothelial growth factor (anti-VEGF) medications, plays a crucial role in managing these disorders and preventing vision loss.

Wet AMD injections are a cornerstone of treatment, aiming to halt disease progression and preserve existing vision. These injections deliver medications directly into the eye to inhibit the growth of abnormal blood vessels and reduce leakage, thereby preserving vision and preventing further damage. The most commonly used medications for wet AMD injections are anti-VEGF agents, such as ranibizumab (Lucentis), aflibercept (Eylea), and bevacizumab (Avastin).

Receiving an injection may seem daunting, but rest assured, it’s a routine procedure performed in a clinical setting. Here’s what to expect:

1. Preparing for the Injection:

• Your ophthalmologist will explain the procedure and address any concerns you have.
• Eye drops may be administered to dilate your pupil and numb the eye, ensuring comfort during the injection.
• Your medical history, including any allergies or previous eye surgeries, will be reviewed to ensure safety.

2. The Injection:

• You’ll be positioned comfortably in a reclined chair or examination table.
• Using sterile techniques, your ophthalmologist will administer the injection into the affected eye, typically targeting the vitreous cavity.
• The procedure is virtually painless due to numbing medication, though you may feel slight pressure or a brief stinging sensation.

3. Post-Injection Care:

• After the injection, you may experience minor discomfort or irritation, which usually subsides quickly.
• Your ophthalmologist will provide post-injection instructions, including any necessary follow-up appointments.
• It’s essential to avoid rubbing or putting pressure on the treated eye and to refrain from strenuous activities for a brief period to minimize the risk of complications.

The frequency of injections varies depending on the severity of your condition and your ophthalmologist’s recommendation. Initially, injections may be more frequent to stabilize the disease, followed by a maintenance schedule to sustain vision gains and prevent relapse. Your ophthalmologist will closely monitor your response to treatment through regular eye examinations and imaging tests, adjusting the injection frequency as needed.

Wet AMD injections offer numerous benefits, including:

• Slowing or halting disease progression.
• Preserving existing vision and potentially improving visual acuity.
• Minimal systemic side effects, as medications are administered directly into the eye.
• Improved quality of life and the ability to perform daily activities independently.

However, it’s essential to consider potential risks and complications, such as:

• Risk of infection, though rare with proper sterile technique.
• Temporary elevation of eye pressure, which may require monitoring and management.
• Potential for retinal detachment, though uncommon and typically manageable with prompt intervention.

Wet AMD injections have transformed the landscape of AMD treatment, offering hope and preserving vision for countless individuals. By understanding what to expect from these injections, you can approach your treatment journey with confidence and optimism. Remember, open communication with your ophthalmologist and adherence to treatment recommendations are key to achieving optimal outcomes in managing wet AMD and related ocular disorders.

In summary, while the thought of injections into the eye may be intimidating, the benefits far outweigh any concerns, ultimately leading to improved quality of life and visual function for those battling wet AMD and other retinal disorders.
