Neovascular Glaucoma: Causes, Signs, and Treatment
Neovascular glaucoma is a type of glaucoma that occurs due to abnormal blood vessel growth in the eye. This condition can lead to increased eye pressure, which can damage the optic nerve and result in vision loss. Neovascular glaucoma can have a significant impact on a person's quality of life by affecting their ability to see clearly and perform daily tasks that require good vision. It is important to seek medical attention promptly if you suspect you may have neovascular glaucoma to prevent further vision loss.
What are the Symptoms of Neovascular Glaucoma?
Neovascular glaucoma is a serious eye condition characterized by certain symptoms that indicate a problem with the eye's blood vessels. These symptoms can vary in severity and are typically indicative of underlying issues that need prompt medical attention. The signs may include changes in vision and eye discomfort. Early detection and treatment are crucial in managing this condition effectively.

Get Second OpinionCauses of Neovascular Glaucoma
Neovascular glaucoma is mainly caused by the abnormal growth of new blood vessels in the eye. These blood vessels can block the normal fluid drainage system, leading to increased eye pressure and damage to the optic nerve. This condition is commonly associated with certain underlying health issues such as diabetes and retinal vein occlusion. Early diagnosis and proper management are crucial in preventing vision loss from neovascular glaucoma.
- Diabetic retinopathy
- Retinal vein occlusion
- Central retinal artery occlusion
- Chronic retinal detachment
- Ischemic central retinal vein occlusion
- Ocular ischemic syndrome
Types of Neovascular Glaucoma
Neovascular glaucoma is a type of secondary glaucoma that is caused by the abnormal growth of blood vessels in the eye. This condition can occur due to various underlying health issues such as diabetes, retinal vein occlusion, or eye trauma. There are different types or forms of neovascular glaucoma, each with its own specific characteristics and causes. These different types may require specific treatment approaches to manage the condition effectively.
- Angleclosure neovascular glaucoma: Caused by abnormal blood vessel growth in the angle of the eye, leading to increased eye pressure and potential vision loss.
- Openangle neovascular glaucoma: Characterized by abnormal blood vessels growing on the iris and obstructing the eye's fluid drainage system, resulting in elevated eye pressure.
- Posttraumatic neovascular glaucoma: Occurs after eye trauma, where abnormal blood vessels develop in response to the injury, causing increased eye pressure.
- Inflammatory neovascular glaucoma: Arises due to inflammation in the eye, triggering abnormal blood vessel growth and subsequent elevation of eye pressure.
- Ischemic neovascular glaucoma: Develops from reduced blood supply to the eye, leading to the formation of new blood vessels that interfere with normal fluid drainage, causing high eye pressure.
Risk Factors
Neovascular glaucoma is a serious eye condition that can lead to vision loss if not treated promptly. Several factors can increase the risk of developing this condition. Identifying these risk factors is crucial for early detection and management.
- Diabetes
- Retinal vein occlusion
- Ocular ischemic syndrome
- History of eye surgery or trauma
- Inflammatory eye conditions
- Agerelated macular degeneration
- Retinopathy of prematurity

Diagnosis of Neovascular Glaucoma
Neovascular glaucoma is typically diagnosed through a series of eye examinations and tests. During these evaluations, an eye specialist will look for specific signs and symptoms that indicate the presence of neovascular glaucoma. These assessments help in confirming the diagnosis and determining the most suitable treatment approach for the patient.
- Tonometry
- Ophthalmoscopy
- Gonioscopy
- Optical coherence tomography (OCT)
- Visual field testing
- Ultrasound biomicroscopy
- Fluorescein angiography
Treatment for Neovascular Glaucoma
Neovascular glaucoma is a type of glaucoma caused by abnormal blood vessel growth in the eye. Treatment options for neovascular glaucoma typically aim to reduce eye pressure and manage the underlying cause of the abnormal blood vessel growth. Common treatment approaches include medications, laser therapy, and surgery. Your eye care provider will recommend the most suitable treatment based on your individual condition and overall health. It is essential to follow your healthcare provider's guidance closely to effectively manage neovascular glaucoma and preserve your vision.
- Medication: Eye drops or oral medications can help reduce eye pressure and control inflammation, slowing down the progression of neovascular glaucoma.
- Laser Therapy: Laser treatment, such as panretinal photocoagulation, can target abnormal blood vessels in the eye, improving drainage and lowering eye pressure.
- Surgery: Invasive procedures like trabeculectomy or tube shunt surgery may be necessary in advanced cases to create new drainage pathways and alleviate eye pressure.
- AntiVEGF Injections: Intravitreal injections of antiVEGF medications can help inhibit abnormal blood vessel growth and reduce neovascularization in the eye.
- Combination Therapy: Sometimes a combination of treatments, like medication with laser therapy or surgery, may be needed to effectively manage neovascular glaucoma and preserve vision.

What is neovascular glaucoma?
Neovascular glaucoma is a type of secondary glaucoma characterized by the growth of abnormal blood vessels on the iris, leading to increased intraocular pressure.
What causes neovascular glaucoma?
Neovascular glaucoma is commonly caused by conditions such as diabetic retinopathy, central retinal vein occlusion, or ocular ischemic syndrome.
What are the symptoms of neovascular glaucoma?
Symptoms may include eye pain, blurred vision, headache, and halos around lights. Increased intraocular pressure can also damage the optic nerve.
How is neovascular glaucoma diagnosed?
Diagnosis typically involves a comprehensive eye exam, measurement of intraocular pressure, evaluation of the optic nerve, and imaging tests like optical coherence tomography (OCT).
What are the treatment options for neovascular glaucoma?
Treatment may include medications to reduce intraocular pressure, laser therapy to target abnormal blood vessels, and sometimes surgery such as trabeculectomy or tube shunt placement.
