What causes decreased vision? What is the likely visual outcome? What can be done to improve vision?

When the retinal vein is blocked, the circulation is greatly slowed. When this happens, the part of the eye which sees (like the film in a camera) does not work as well as it should. The ultimate visual outcome cannot be predicted. A few patients, with time, have spontaneous improvement in vision. Some patients get worse. Currently, there is no known way to improve vision. Laser, eye drops and glasses will not help.
