The Branch Retinal Vein Occlusion (BRVO) is a common retinal vascular disorder that occurs when there is a blockage of the small veins in the retina. This blockage can lead to a buildup of blood and fluid, causing swelling and damage to the retina, and potentially leading to vision loss.

Causes[edit | edit source]

BRVO is often caused by atherosclerosis, hypertension, diabetes, and other systemic diseases. It can also be associated with glaucoma and macular edema.

Symptoms[edit | edit source]

Symptoms of BRVO can include sudden, painless vision loss or distortion, floaters, and a dark or empty area in the field of vision.

Diagnosis[edit | edit source]

Diagnosis of BRVO is typically made through a comprehensive eye examination, including fundus photography, fluorescein angiography, and optical coherence tomography.

Treatment[edit | edit source]

Treatment options for BRVO can include laser photocoagulation, intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF) agents, and corticosteroids. In some cases, vitrectomy may be necessary.
