Neovascular Glaucoma: Symptoms and Treatment


Neovascular glaucoma (NVG) occurs when blood vessels grow over the iris and the anterior chamber of the eye. This can impede fluid drainage, increase intraocular pressure, and affect vision.

Blood vessels can also bleed and pressure can rise significantly. This can cause irreversible damage to the optic nerve.

NVG is a serious condition that can lead to blindness if not properly treated.that link to Conditions such as diabetic retinopathy, central retinal vein occlusion, and carotid artery disease (CAD).

This article provides an overview of NVG, including its causes, symptoms, diagnosis, and treatment options.

NVG is a disease that damages the optic nerve of the eye. Unlike other types of glaucoma, it develops when atypical blood vessels grow in parts of the eye.

These new blood vessels block the drainage of fluid from the eye, often resulting in a leak. As a result, intraocular pressure increases and can cause vision loss if left untreated.

NVG is not life-threatening, but can cause permanent vision loss.doctor associate it Poor human vision.

Early detection and appropriate treatment improve the outlook for NVG patients.

NVG is a form of secondary glaucoma. This means that it develops due to another underlying disease, such as diabetic retinopathy, ocular ischemic syndrome, or ischemic central retinal vein occlusion.

These conditions can block or damage the blood vessels in the eye, preventing the retina from getting enough oxygen. As a result, the retina tries to fix the problem by releasing a chemical known as vascular endothelial growth factor (VEGF).

This chemical causes new blood vessels to grow, bringing more oxygen to the retina. However, these new blood vessels can also interfere with the drainage and leakage of ocular fluid.

less common Causes of NVG include:

In the early stages, there may be no symptoms of NVG. Photosensitivity and blurred vision may be the first signs.As symptoms progress, a person may may experience:

  • pain
  • bloodshot eyes
  • poor vision

Pain and redness may not be as intense, especially in younger people.

NVG diagnostics include: comprehensive eye examination evaluate:

  • pressure in the eye
  • Optic Nerve and Anterior Chamber Health
  • eye drainage angle
  • human vision

Your eye doctor may also perform imaging tests to help diagnose the disease and monitor its progression.

To treat NVG effectively, it is imperative that a doctor identify the underlying cause of NVG only by addressing the cause.

If the cause is not yet clear, your doctor may take a detailed medical history to identify risk factors for NVG and order additional tests to check for conditions such as diabetes and CAD.

Treatment of NVG involves treating or managing the underlying cause of symptoms and lowering intraocular pressure to prevent damage to the optic nerve.

How doctors deal with the underlying cause depends on the cause, but generally the goal is to manage the decreased blood flow to the retina and reduce the formation of new blood vessels. Doctors can use different approaches for this, including:

  • Laser treatment to reduce VEGF production, known as panretinal photocoagulation
  • Injecting an anti-VEGF drug directly into the eye to promote the loss of new blood vessels

The first-line approach to lowering intraocular pressure is often eye drops or oral medications.

If drug or laser therapy is unsuccessful, your doctor may recommend placing a tube shunt in your eye to lower the pressure in your eye.

However, for people with poor vision, an eye doctor may recommend a less invasive laser procedure to destroy the ciliary body, the part of the eye that produces fluid.

Management of NVG often involves a team of specialists, including glaucoma and retinal specialists, ophthalmologists, and primary care physicians. These medical professionals work together to ensure that individuals receive optimal care and minimize the risk of complete vision loss.

NVG is a type of secondary glaucoma that occurs as a result of conditions such as diabetic retinopathy that result in blood loss from the retina.

In response to the lack of blood, the eye grows new blood vessels, preventing fluid from draining out of the eye. These new blood vessels can also leak.

This can increase intraocular pressure, damage the optic nerve, and cause vision loss. There may be no symptoms at first.

Doctors diagnose symptoms through a comprehensive eye exam. Treatment may include a combination of drugs, laser therapy, or surgery.
