Retinal Vein Occlusion​

Like many Canadians, you may have never heard of Retinal Vein Occlusion (RVO) or macular edema. RVO is a disorder of the retina that can lead to vision loss and cause blindness in some patients.

RVO is a blockage of the veins in the retina that carry blood away from the eye. The blockage can cause fluid to leak into the macula – the part of the eye where focusing occurs. The swelling, called macular edema, can cause blurred vision and sometimes complete vision loss.

The blockage caused by RVO cannot be reversed, but there are ways in which it can be managed, using treatments​ that may slow down the progression of vision loss and even greatly improve your vision.
