Hi. I'm online and happy to answer your question today.
A pulmonary embolism, in and of itself, would not cause decreased vision. However, it is possible that a clot could have gone to your eye in addition to going to your lung. If this was the case your vision would be affected.
From what you have posted it is important for you to have a complete eye examination by an ophthalmologist ASAP.
Does this make sense to you?
