Central Retinal Venous Occlusion

A vascular disorder where the central retinal vein is blocked, causing fluid leakage and vision problems.

Causes

Several factors may contribute to the development of CRVO, including:

Aging

The risk of CRVO increases with age.

Systemic diseases

Conditions such as hypertension, diabetes, and vascular disorders can increase the risk.

Glaucoma

Increased intraocular pressure may play a role.

Blood disorders

Conditions that affect blood clotting can contribute to CRVO.

Symptoms

Symptoms of Central Retinal Vein Occlusion may include sudden vision loss, blurry or distorted vision, and the perception of a dark area or shadow in the central visual field.

Management

The prognosis for individuals with CRVO can vary, and while some may experience spontaneous improvement, others may face persistent vision issues. Regular eye exams, management of underlying health conditions, and early intervention can help optimize outcomes for individuals with Central Retinal Vein Occlusion. If you suspect any issues with your vision, it's important to consult with an eye care professional for a thorough examination and appropriate management.

Treatment

The management of CRVO aims to address underlying systemic conditions and manage complications. Treatment options may include:

Anti-VEGF injections

These medications can help reduce abnormal blood vessel growth and swelling.

Corticosteroids

In certain cases, steroids may be used to reduce inflammation.

Laser therapy

This may be employed to treat abnormal blood vessels.

Intravitreal Injection

An injection directly into the vitreous cavity allowing for a higher concentration of medicine to reach the retina and other structures in the eye.

Laser Photocoagulation

A laser treatment that helps to seal leaky eye vessels to prevent vision loss from diabetes, tears, or abnormal growths.

Normal vision vs. Central Retinal Venous Occlusion

Overview

Central Retinal Vein Occlusion (CRVO) is a vascular disorder that affects the eye, particularly the retina. In CRVO, there is a blockage or obstruction in the central retinal vein, which is responsible for carrying deoxygenated blood away from the retina. This blockage can lead to a buildup of pressure in the blood vessels, causing fluid leakage and various complications that can affect vision.

Types of CRVO

CRVO is generally classified into two main types:

Non-ischemic CRVO

In this form, blood flow to the retina is still partially maintained despite the blockage. While vision loss can occur, it may not be as severe as in ischemic CRVO.

Ischemic CRVO

This type involves a more severe blockage, leading to a significant reduction in blood flow to the retina. Ischemic CRVO is associated with a higher risk of vision loss and complications.

Management

The prognosis for individuals with CRVO can vary, and while some may experience spontaneous improvement, others may face persistent vision issues. Regular eye exams, management of underlying health conditions, and early intervention can help optimize outcomes for individuals with Central Retinal Vein Occlusion. If you suspect any issues with your vision, it's important to consult with an eye care professional for a thorough examination and appropriate management.
