Branch Retinal Vein Occlusion (BRVO) Symptoms
The most common symptom of BRVO is vision loss or blurry vision in part or all of one eye. It can happen suddenly or become worse over several hours or days. Sometimes, you can lose all vision suddenly.
You may notice floaters. These are dark spots, lines or squiggles in your vision. These are shadows from tiny clumps of blood leaking into the vitreous from retinal vessels.
BRVO almost always happens only in one eye.
