Eye Injections for Retinal Diseases: Anti-VEGF Treatment

These injections are used to halt or slow disease progression in conditions such as age-related macular degeneration, diabetic retinopathy, and retinal vein occlusions. The goal is to support vision preservation, reduce symptoms like blurry vision or dark spots, and prevent further damage to your retina.

Our retina specialists select medications tailored to each diagnosis:

• Anti-VEGF agents like Eylea, Eylea HD (aflibercept 8 mg), Lucentis, Vabysmo (faricimab), and Avastin to reduce abnormal blood vessel growth and fluid leakage
• Corticosteroids such as Ozurdex, Trivaris, and fluocinolone implants (e.g., Iluvien or Yutiq) to control inflammation and swelling
• Complement inhibitors for geographic atrophy (advanced dry AMD) such as Syfovre (pegcetacoplan) and Izervay (avacincaptad pegol) to slow disease progression
• Combination therapies that target multiple disease pathways
• Other specialized medications based on your specific retinal condition and response to treatment

The medication acts by targeting harmful factors inside the eye that cause disease. Anti-VEGF drugs block proteins that make blood vessels leak and grow abnormally. Steroids reduce inflammation and swelling. These actions help restore healthier retinal tissue, with the goal of stabilizing or improving your vision over time.

The vitreous is the clear, gel-like substance that fills the inside of your eye. By injecting medicine directly into this space, we can deliver high concentrations of medication exactly where your retina needs it most, while minimizing effects on the rest of your body.

Initial recovery recommendations for optimal healing:

• Avoid rubbing, touching, or pressing on the treated eye
• Use preservative-free artificial tears as needed for irritation
• Refrain from swimming, hot tubs, or getting water directly in your eye
• Keep your head elevated when resting to reduce swelling
• Avoid dusty or dirty environments that could irritate your eye
• Sleep on the opposite side of your treated eye if possible

For ongoing comfort and healing over the next several days:

• Use preservative-free artificial tears as needed for dryness or irritation
• Wear sunglasses outdoors to reduce light sensitivity
• Small floaters, blood spots, or mild irritation may occur and usually resolve within a week
• You may resume normal activities like reading, watching TV, and light exercise
• Continue all regular medications unless specifically told otherwise
• Gentle face washing is fine, but avoid getting soap or water directly in the treated eye

Please contact Retina Consultants, PA promptly if you experience any of these warning signs:

• Severe or worsening eye pain that doesn't improve with over-the-counter pain medicine
• Sudden vision loss or significant decline in vision beyond normal post-injection blurriness
• Signs of infection: increasing redness, yellow or green discharge, or eyelid swelling
• Persistent flashing lights or a sudden increase in new floaters
• Extreme light sensitivity that doesn't improve after the first day
• Appearance of a new shadow, curtain, or veil in your vision
• Any other symptoms that concern you or seem unusual

We'll schedule your next visit before you leave. These appointments are crucial for monitoring your progress and determining when your next injection is needed. Please keep all scheduled appointments, as missing follow-ups can affect your treatment results.

Most patients are surprised by how comfortable the procedure is. We use multiple numbing drops to eliminate pain, and the injection itself takes only seconds. You may feel slight pressure or see a brief shadow, but significant pain is very rare.

Treatment schedules vary based on your condition and response. Most patients start with monthly injections for 3-6 months, then may extend to every 6-12 weeks or longer. Some conditions require more frequent treatment, while others may need injections only a few times per year.

Serious complications are very rare when injections are performed by experienced specialists:

• Infection (endophthalmitis) occurs in about 1 in 2,000–5,000 injections
• Retinal detachment is extremely rare
• Temporary redness, irritation, or new floaters are more common but usually mild
• Eye pressure may increase temporarily, especially in patients with glaucoma

Vision response varies by person and condition. Some patients notice improvement within days or weeks, while others may need several injections before seeing benefits. Even if vision doesn't improve, stopping further vision loss is often considered successful treatment.

Yes, most patients can return to normal activities the same day. Avoid rubbing your eye, swimming, or getting water directly in the treated eye for 24 hours. Follow all specific aftercare instructions provided by our team.

We strongly recommend arranging transportation, as your vision may be blurry or light-sensitive immediately after the injection. This usually improves within a few hours, but it's safer to have someone drive you home.

In most cases, yes. Blood thinners like aspirin, Plavix, or warfarin don't need to be stopped for eye injections. Always inform our office about all medications you take, and we'll provide specific guidance for your situation.

Anti-VEGF medications typically provide benefits for 4-8 weeks, which is why injections are usually given monthly or every 6-8 weeks. Steroid injections may last longer, sometimes 3-4 months, depending on the specific medication used.

Missing appointments can allow your retinal disease to worsen and may undo previous treatment benefits. If you must miss an appointment, contact our office immediately to reschedule as soon as possible.

Get a good night's sleep, eat a light meal beforehand, and arrive well-rested. Consider bringing a support person if it helps you feel more comfortable. Practice slow, deep breathing, and remember that most patients find the experience much easier than they expected.

Contact our office if you have worsening pain, vision changes, or any concerning symptoms that don't improve as expected. While most side effects are mild and temporary, we want to evaluate any symptoms that worry you or persist longer than normal.

Newer extended-release medications and implantable drug delivery devices are being developed that may reduce injection frequency in the future. Currently, we tailor your injection schedule to use the minimum frequency needed to maintain your vision benefits.

This depends on your specific condition. Some patients with acute problems may need only a few injections, while others with chronic diseases like macular degeneration may need ongoing treatment. We'll discuss long-term expectations based on your particular diagnosis.

We monitor your progress through vision testing, OCT scans, and eye exams at each visit. Even if your vision doesn't improve dramatically, stable vision often means the treatment is successfully preventing further damage from your retinal disease.

While it's medically possible, we typically prefer to inject eyes on different days to reduce the small risk of complications affecting both eyes simultaneously. We'll discuss the best schedule for your particular situation.
