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

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

Symptoms

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

Diagnosis

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

Treatment

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.
