Branch Retinal Venous Occlusion

A vascular disorder where a branch vein in the retina is blocked, disrupting blood flow and causing vision problems.

Causes

BRVO typically occurs at points where the retinal veins and arteries cross, and it can affect either the superior or inferior branch of the retinal vein. The obstruction in blood flow can lead to swelling (edema), hemorrhages, and other changes in the retina, causing vision problems.

Symptoms

Sudden onset of blurry or distorted vision in one eye The appearance of floaters (dark spots or specks that seem to float in the field of vision) Visual field defects, such as a dark area or shadow in the visual field Risk factors for BRVO are similar to those for CRVO and may include aging, hypertension, diabetes, and other vascular diseases.

Management

The prognosis for individuals with BRVO can vary, and outcomes depend on factors such as the extent of the blockage, the location of the occlusion, and the presence of underlying health conditions. Regular eye exams and early intervention are important for optimizing outcomes and preventing complications. If you experience sudden changes in vision or suspect any issues with your eyes, it's crucial to consult with an eye care professional for a comprehensive examination and appropriate management.

Treatment

The management of Branch Retinal Vein Occlusion aims to address underlying conditions and manage complications. Treatment options may include:

Anti-VEGF injections

Medications that inhibit the vascular endothelial growth factor (VEGF) can help reduce abnormal blood vessel growth and edema.

Corticosteroids

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

Laser therapy

Laser treatment may be employed to address abnormal blood vessels and reduce edema.

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. Branch Retinal Venous Occlusion

Overview

Branch Retinal Vein Occlusion (BRVO) is a vascular disorder that affects the retina, similar to Central Retinal Vein Occlusion (CRVO). In BRVO, one of the branch veins that drains blood from a specific portion of the retina becomes blocked, leading to a disruption in blood flow. This blockage can result in various complications that impact vision in the affected area.

Management

The prognosis for individuals with BRVO can vary, and outcomes depend on factors such as the extent of the blockage, the location of the occlusion, and the presence of underlying health conditions. Regular eye exams and early intervention are important for optimizing outcomes and preventing complications. If you experience sudden changes in vision or suspect any issues with your eyes, it's crucial to consult with an eye care professional for a comprehensive examination and appropriate management.
