Branch Retinal Vein Occlusion

What's going on?

One of the small veins within the eye has become blocked. This
usually happens at a point where an artery crosses a vein. Back pressure
causes rupture of the veins in a specific part of the retina. The
vision in that area is reduced. If the blockage is close to the most
important area of the retina (the macula) your vision will be reduced.
If the blockage involves a less important area you may not even know
that anything has occurred.

What will my ophthalmologist see?

There will be retinal haemorrhages localised to one area of the retina.

What will my ophthalmologist do for me?

We will be able to advise you with regards how severe the damage is
and the likely prognosis for vision. Sometimes laser therapy can help to
dry up any leakage and improve your vision.

What can I do?

It is important that your blood pressure is controlled.

What do I need to know?

The visual prognosis is variable and really dependant upon the area of the retina which has been affected.
