A blood clot stops the vein in the retina, causing retinal vein occlusion. It can happen when the veins in the eyes are too narrow. It is more common in persons who have diabetes, as well as those who have high blood pressure, high cholesterol, or other health issues that influence blood flow. The signs and symptoms of retinal vein blockage range from mild to severe. There is no pain associated with the blurring or loss of eyesight. Almost always, it just affects one eye. The blurring or loss of vision may be minor at first but gradually worsens over the next few hours or days. Occasionally, full visual loss occurs nearly instantly.
