Neovascular Glaucoma (NVG) Treatment In Jaipur At Pink City Eye & Retina Center

At Pink City Eye & Retina Center in Jaipur, we are committed to preserving and protecting your vision, especially when it comes to complex and potentially blinding eye diseases. One such challenging condition is Neovascular Glaucoma (NVG)—a rare but highly aggressive form of glaucoma that requires urgent attention and expert management.

This guide will help you understand what NVG is, what causes it, how it develops, and how we can treat it effectively in Jaipur.

What Is Neovascular Glaucoma (NVG)?

Neovascular Glaucoma is classified as a secondary glaucoma, which means it does not occur on its own, but rather as a result of another eye or systemic disease—typically conditions that cause poor blood supply to the retina.

In NVG, abnormal new blood vessels (neovascularization) begin to grow on the surface of the iris (the colored part of the eye) and into the angle where the cornea and iris meet—the area responsible for draining fluid (aqueous humor) from the eye. These new vessels are weak and irregular, and their presence can block fluid outflow, leading to a dangerous rise in intraocular pressure (IOP).

If pressure isn’t controlled early, optic nerve damage and permanent vision loss may occur. Unlike primary glaucoma, which often develops slowly and without a known cause, NVG is always linked to an underlying problem—most commonly ischemic retinal diseases.

Causes of Neovascular Glaucoma

The main driving factor behind NVG is retinal ischemia—a state in which the retina does not receive enough oxygen and nutrients due to poor or obstructed blood flow. In response, the retina releases a chemical called VEGF (Vascular Endothelial Growth Factor), which stimulates the growth of new blood vessels in an attempt to restore oxygen supply. However, these new vessels are abnormal and grow in places where they shouldn’t—such as the iris and drainage angle.

Most common underlying conditions leading to NVG include:

Proliferative Diabetic Retinopathy – Proliferative Diabetic Retinopathy is a diabetes complication that causes abnormal blood vessels to grow on the retina.
Central Retinal Vein Occlusion (CRVO) – Central Retinal Vein Occlusion (CRVO) is a sudden blockage in the main retinal vein, causing swelling and reduced blood flow.
Ocular Ischemic Syndrome – Ocular Ischemic Syndrome happens when the eye gets less blood, often due to clogged carotid arteries.
Chronic Retinal Detachment – Long-standing separation of the retina from its underlying tissue, depriving it of nourishment.
Intraocular Tumors – Although rare, certain tumors can disrupt normal retinal function and trigger neovascularization.

How Does NVG Progress?

The development of neovascular glaucoma follows a clear and harmful chain of events:

Retinal ischemia triggers the release of VEGF.
Abnormal new vessels begin to grow on the iris and into the angle of the eye.
These weak vessels stir inflammation and scar tissue formation.
This fibrous tissue gradually closes off the drainage angle, preventing aqueous fluid from exiting the eye.
As fluid accumulates, eye pressure rises, harming the optic nerve and reducing vision.

Symptoms of Neovascular Glaucoma

Early neovascular glaucoma may show no clear signs. As the condition progresses and eye pressure increases, the following symptoms may occur:

Persistent eye redness
Mild to severe eye pain
Blurry or suddenly reduced vision
Halos or rainbow rings around lights
Sharp eye pain or headache (in advanced stages)
Complete loss of vision (if untreated)

If you are diabetic, have suffered a retinal vein occlusion, or have a known retinal disease and start experiencing these symptoms, seek urgent care at Pink City Eye & Retina Center.

How We Diagnose Neovascular Glaucoma (NVG) In Jaipur At Pink City Eye & Retina Center

Diagnosing NVG involves more than just checking eye pressure. We perform a comprehensive set of tests to confirm both the glaucoma and its underlying cause:

Slit-Lamp Biomicroscopy

Allows detailed inspection of the iris to detect abnormal vessel growth.

Gonioscopy

Gonioscopy uses a special lens to check the drainage angle for new blood vessels or scarring.

Tonometry

Measures intraocular pressure to check for elevation.

Fundus Examination & OCT (Optical Coherence Tomography)

Evaluates the retina and optic nerve for signs of ischemia and damage.

Fluorescein Angiography

Fluorescein Angiography uses dye to image retinal blood flow and locate areas lacking blood supply.

Treatment Options for Neovascular Glaucoma In Jaipur At Pink City Eye & Retina Center

Effective management of NVG requires a two-fold approach:

1. Control the Underlying Retinal Disease

Panretinal Photocoagulation (PRP):
This laser treatment targets ischemic (oxygen-starved) areas of the retina to reduce VEGF production. It’s one of the first steps in halting abnormal vessel growth.
Intravitreal Anti-VEGF Injections:
Medications like Bevacizumab (Avastin), Ranibizumab (Lucentis), or Aflibercept (Eylea) are injected directly into the eye to shrink and prevent further abnormal vessel growth.

2. Lower Intraocular Pressure

In many cases, eye drops or oral medications may temporarily lower IOP, but surgery is often necessary for long-term control. Options include:

Glaucoma Drainage Implants (e.g., Ahmed or Baerveldt Valve):
These devices divert fluid from the inside of the eye to a reservoir under the outer layer of the eye.
Cyclophotocoagulation:
A laser procedure that reduces the amount of fluid produced by the eye, helping lower pressure.
Trabeculectomy:
A traditional glaucoma surgery that creates a new drainage channel; however, it’s less effective in NVG due to the tendency for scar tissue to block the new channel.

Conclusion

Neovascular Glaucoma is a rapidly progressing and severe eye condition that poses a serious risk to vision. It is often triggered by retinal illnesses and can permanently damage vision if not treated promptly. Although complete recovery of lost vision may not always be possible, early diagnosis and timely intervention in Jaipur can greatly reduce the risk of further damage and help preserve the remaining eyesight.

At Pink City Eye & Retina Center in Jaipur, we focus not just on lowering eye pressure, but also on managing the root cause of the disease to provide comprehensive, long-term care.

If you or a loved one are at risk, act now—schedule an eye exam in Jaipur today, because every moment counts.

Frequently Asked Questions (FAQs)

Can Neovascular Glaucoma be completely cured?

Neovascular glaucoma (NVG) can’t be reversed, but it can be controlled—early treatment of the underlying cause and eye pressure is essential.

Is there any way to prevent NVG?

Yes. The best prevention is to treat the root causes early—especially diabetic retinopathy and retinal vein occlusion. Regular eye exams, especially for diabetics, help catch issues early.

Is neovascular glaucoma a form of secondary glaucoma?

Yes, neovascular glaucoma is a type of secondary glaucoma that develops due to other eye or systemic conditions, like diabetic retinopathy or retinal vein occlusion. It’s caused by abnormal blood vessel growth that blocks the eye’s fluid drainage system.

How does diabetes lead to neovascular glaucoma?

Diabetes can damage the retina, causing low oxygen levels. In response, the eye releases VEGF, which creates abnormal blood vessels on the iris and drainage angle—leading to blocked fluid flow and high eye pressure.

Can high blood pressure cause neovascular glaucoma?

High blood pressure doesn’t directly cause NVG but can worsen retinal diseases, like vein occlusion, which can trigger abnormal vessel growth and lead to glaucoma.

What does eye pain in neovascular glaucoma feel like?

The pain is usually severe, deep, and throbbing, often with redness and blurred vision. It’s caused by a sudden pressure spike in the eye when drainage is blocked.

How fast does neovascular glaucoma progress?

NVG can progress very quickly, especially if untreated. Vision loss and pressure buildup can happen over weeks to months, based on the cause and severity.

Can neovascular glaucoma be cured?

There’s no cure, but NVG can be managed. Treatments aim to control eye pressure and reduce abnormal blood vessel growth to preserve vision and reduce symptoms.

Is surgery necessary for neovascular glaucoma?

In many cases, yes. If medications and laser fail, surgery like drainage implants or laser cyclophotocoagulation may be needed to lower eye pressure.

Are there medications to manage neovascular glaucoma?

Yes, NVG is treated with eye drops, oral medications, and anti-VEGF injections. These help reduce pressure and shrink abnormal blood vessels.

What is the success rate of treatment for neovascular glaucoma?

Success depends on how early it’s caught. Early treatment can control pressure in 60–80% of cases. Advanced stages often need surgery, with variable outcomes.

How effective is laser treatment for neovascular glaucoma?

Laser treatment like PRP is effective early on. It reduces abnormal vessel growth by lowering retinal oxygen demand, especially when combined with anti-VEGF therapy.
