Quick Overview

Anti-VEGF eye injections block vascular endothelial growth factor (VEGF), a protein that promotes abnormal blood-vessel growth and increases vascular leakage in the eye. Anti-VEGF injections are a mainstay of treatment for neovascular (“wet”) age-related macular degeneration (AMD), diabetic macular oedema, and macular oedema associated with retinal vein occlusion. Many patients begin with a series of closely spaced injections, followed by a maintenance schedule based on the underlying condition and the eye’s response to treatment. Maintenance dosing follows, based on the eye’s response.

• Anti-VEGF medicines used for retinal conditions in India include bevacizumab, ranibizumab and aflibercept, along with approved biosimilar products. The specific medicine used depends on the diagnosis, regulatory approval, availability and the ophthalmologist’s assessment. 
• An intravitreal injection delivers the medicine into the vitreous cavity after the eye has been numbed and prepared with an antiseptic. 
• Some treatment regimens begin with monthly loading doses, while others use different initial schedules. Maintenance may involve fixed intervals, treat-and-extend dosing, or treatment based on disease activity, depending on the drug and condition. 
• These injections aim to stabilise vision and reduce leakage. They don’t guarantee restoring vision already lost.

If you’ve been told you need an anti-VEGF injection, it’s natural to have questions first. Booking a retina specialist consultation is the best place to start.

These injections have become the standard, evidence-based treatment for several retinal conditions that once had far fewer options. Anti-VEGF injections for macular degeneration, in particular, have changed the outlook for wet AMD. Without effective treatment, wet AMD can cause significant, sometimes rapid, loss of central vision. 

This guide covers how the medication works and which drugs are used in India. It also covers the injection visit, dosing, and how many macular degeneration injections you might need. Realistic costs and side effects come last.

What Are Anti-VEGF Eye Injections and How Do They Work?

Anti-VEGF stands for anti-vascular endothelial growth factor. These medications block VEGF, a naturally occurring signalling protein whose levels can increase in response to factors such as reduced oxygen availability and inflammation. In wet AMD, anti-VEGF treatment helps reduce abnormal blood-vessel growth and vascular leakage, limiting fluid or blood accumulation in and around the macula. 

What does VEGF do to the leaking blood vessels in your retina?

Excess VEGF can promote the growth of abnormal, fragile blood vessels and increase vascular permeability, allowing fluid or blood to leak into retinal tissues. In the retina, this leads to swelling and distorted vision.

An anti-VEGF medicine blocks this signalling pathway, helping reduce abnormal vascular leakage and retinal swelling. 

Which eye conditions are treated with an anti-VEGF intravitreal injection?

The clinical term for this treatment is an intravitreal injection. The drug goes directly into the vitreous gel of the eye. Anti-VEGF injections are commonly used to treat diabetic macular oedema and macular oedema associated with retinal vein occlusion. They may also be used in certain cases of proliferative diabetic retinopathy, particularly when abnormal blood-vessel growth is present. 

Which Anti-VEGF Injections Are Available in India?

Several anti-VEGF injections for macular degeneration and diabetic eye disease are available in India. They differ in their active molecule, approved indications, dosing schedules, evidence base, availability and cost. Your ophthalmologist chooses based on your specific condition, not a one-size-fits-all rule.

How do Avastin, Accentrix, Eylea and Pagenax compare?

Bevacizumab (Avastin) is commonly used off-label for several retinal conditions and is generally less expensive than medicines specifically developed and approved for ophthalmic use. Ranibizumab (Accentrix) and aflibercept (Eylea) are anti-VEGF medicines with ophthalmic indications. Biosimilar products may provide additional options, with pricing varying by brand and centre. 

What are biosimilars like Razumab, and are they as effective?

Razumab is a biosimilar of ranibizumab, developed to demonstrate high similarity to the reference medicine in quality, biological activity, and clinical performance. Clinical studies have evaluated ranibizumab biosimilars for retinal conditions, with evidence supporting their similarity to the reference product when used in appropriate patients. 

Some patients search for anti vegf injections for macular degeneration priced lower than the original brand. Biosimilars may offer a more affordable treatment option when an appropriate product is available and suitable for the patient. Your specialist will still weigh your specific case before recommending one.

What Happens During an Anti-VEGF Injection?

The injection itself takes only a few minutes, although the overall appointment may take longer because of preparation and post-injection assessment. Most patients don’t need any special preparation beforehand.

What are the steps, from numbing drops to the injection itself?

First, the doctor applies numbing drops, then uses an antiseptic to clean the eye. A small device keeps the eyelids gently open during the injection. The doctor uses a very fine needle to deliver the medicine through the white part of the eye into the vitreous cavity. 

Is the injection painful, and how long does it take?

With the eye numbed beforehand, many patients feel pressure or mild discomfort rather than significant pain during the injection. The injection itself takes only seconds. The full visit, including prep and a brief check afterwards, runs about 10 to 15 minutes. Mild grittiness for a day or two is common.

How Many Injections Will You Need?

No fixed number applies to everyone. Your treatment plan depends on the condition being treated, how your eye responds, and which dosing approach your specialist follows.

What is the difference between loading doses, monthly dosing and treat-and-extend?

Initial treatment often involves several injections given at relatively short intervals, although the exact schedule varies by drug and condition. After that, some patients continue monthly. Others move to treat-and-extend, where the gap between visits lengthens gradually if the eye stays stable. Another approach is as-needed treatment, in which the eye is monitored regularly and another injection is given when there are signs of disease activity. 

What happens if you miss or stop your injections?

Delaying or missing recommended injections can allow disease activity to return and may increase the risk of further vision loss. In conditions such as wet AMD, prolonged gaps in treatment may allow disease activity to recur and can be associated with poorer visual outcomes. If you need to reschedule, contact your eye specialist rather than simply skipping the appointment.

How Much Do Anti-VEGF Eye Injections Cost in India?

Costs for anti-VEGF injections for macular degeneration and diabetic eye disease vary widely. They depend on the drug, the clinic, and how many injections your course requires. Rather than quoting a single figure, it helps to think in tiers.

What does one injection cost by drug, and what does a full course add up to?

Bevacizumab (Avastin) sits at the lower end, since it’s used off-label and isn’t priced as a dedicated eye drug. Biosimilars such as Razumab and Pagenax generally cost less than the original branded molecules they’re modelled on.

Branded anti-VEGF medicines may cost more than off-label bevacizumab or some biosimilar alternatives, although prices vary by product, centre and treatment setting. Because a full course often means several injections over months, costs vary by centre and case. Confirm exact pricing at your consultation.

Does health insurance or Ayushman Bharat cover eye injections?

Coverage depends heavily on your specific policy or scheme, so there’s no single answer here. Some private health insurance plans cover eye injections for macular degeneration and diabetic retinopathy under specific conditions. Others exclude them entirely.

Coverage under Ayushman Bharat PM-JAY depends on the applicable package, beneficiary eligibility, treatment facility and current scheme rules. Patients should confirm whether their specific retinal treatment and medicines are covered before treatment. For billing and insurance guidance, confirm your position directly with your insurer or TPA before treatment.

What Are the Side Effects and Risks?

Anti-VEGF injections are generally well tolerated, although serious complications can occur rarely. Still, it helps to know what’s normal and what isn’t.

Which common effects settle on their own?

Mild redness, watering, and a gritty feeling are common for a day or two. A small red patch on the white of the eye, known as a subconjunctival haemorrhage, can also occur and usually resolves on its own. It usually fades within a week or two. Temporary blurred vision can occur immediately after the injection and usually improves as the effect of the procedure wears off. 

Which warning signs need same-day medical attention?

Severe or worsening eye pain, a significant drop in vision, increasing redness, marked light sensitivity, or new discharge require urgent ophthalmic assessment the same day. Rare but serious complications like infection can present this way, so don’t wait them out.

Conclusion: Choosing the Right Anti-VEGF Injections for Macular Degeneration

Anti-VEGF therapy has significantly improved the treatment of several retinal conditions, including neovascular AMD and diabetic macular oedema. Before anti-VEGF therapy became available, treatment options for several of these retinal conditions were more limited. 

The right drug, dosing schedule, and cost plan depend on your specific diagnosis and how your eye responds over time. If you’ve been advised to start treatment, ask your retina specialist to walk you through the options. If cost is a concern, ask your ophthalmologist whether an appropriate biosimilar is available for your condition. 

Frequently Asked Questions

Will anti-VEGF injections restore vision that is already lost?

Usually not fully. These injections mainly aim to stabilise vision and reduce further damage from leakage or abnormal vessels. Some patients do see partial improvement, especially when treatment starts early, but restoring vision already lost isn’t guaranteed.

Can you drive home after an eye injection?

Your vision may be temporarily blurry right after the injection. Most clinics recommend arranging a companion or driver for that day, just to be safe.

Avastin vs Accentrix: how does your surgeon choose?

This is a clinical decision, not simply a cost comparison. Avastin (bevacizumab) is used off-label for eye conditions, while Accentrix (ranibizumab) is specifically approved for retinal use. Your surgeon weighs your diagnosis, response history, and overall health before recommending either.

How long does one anti-VEGF injection last?

The effect typically lasts several weeks to a couple of months, depending on the drug and your individual response. That’s why most treatment plans involve repeat anti-VEGF injections for macular degeneration or diabetic eye disease. A single visit usually isn’t enough.
