Central Retinal Vein Occlusion (CRVO) is a serious eye condition where the central vein in the retina gets blocked, leading to sudden vision loss. The retina is the part of your eye that sends visual signals to the brain. When the vein is blocked, blood and fluid leak into the retina, causing swelling and impaired vision.
Early diagnosis and prompt treatment are crucial to prevent further vision loss and possible complications.
CRVO usually occurs due to underlying health conditions that affect blood circulation. Some common causes include:
There are two main types of CRVO:
Non-Ischemic CRVO
This is a less severe form, where partial blockage occurs. Symptoms might be milder, and vision loss is gradual.
Ischemic CRVO
This is the more serious form, involving complete blockage of the vein, leading to more severe vision loss and a higher risk of complications like neovascular glaucoma.
CRVO symptoms can vary depending on the severity of the condition, but common signs include:
If you notice any of these symptoms, especially if they appear suddenly, it’s critical to see an eye specialist like Dr. Suraj Munjal immediately.
To diagnose CRVO, Dr. Suraj Munjal will perform a thorough eye examination, which includes:
Visual Acuity Test
To measure how well you can see.
Dilated Eye Exam
To look closely at the retina and check for signs of damage.
Optical Coherence Tomography (OCT)
A high-resolution scan that helps detect swelling and fluid buildup in the retina.
Fluorescein Angiography
A test using dye to visualize blood flow and identify any blockages.
Treatment for CRVO focuses on managing the underlying cause, reducing retinal swelling, and preventing complications. Depending on the severity, Dr. Suraj Munjal may recommend:
Anti-VEGF Injections
These injections help reduce retinal swelling and improve vision by blocking the growth of abnormal blood vessels.
Steroid Injections
Steroids can reduce inflammation and prevent fluid buildup in the retina.
Laser Therapy
In some cases, laser treatment may be necessary to close leaking blood vessels and prevent further damage.
Managing Underlying Conditions
Controlling high blood pressure, diabetes, and cholesterol is vital to prevent further episodes of CRVO.
India is known for providing world-class medical treatment at an affordable cost. The cost of CRVO treatment can vary based on the type of procedure required and the severity of the condition. On average:
If left untreated, CRVO can lead to permanent vision damage, especially in cases of ischemic CRVO. Early treatment helps improve the outcome.
The recovery time varies depending on the treatment and the severity of the blockage. Most patients see gradual improvement in vision after anti-VEGF or steroid injections.
Yes, CRVO treatment is possible and recommended for elderly patients. However, managing underlying conditions like high blood pressure and diabetes is crucial for treatment success.
CRVO usually affects only one eye, but there is a small chance it can occur in both eyes over time.
