Joja,I am sorry to read of your problem as well as the anxiety is is causing you. So often it is difficult to know which came first the vision problem then anxiety or anxiety causing the vision problem.
From what I have read, visible pulsations in the eye that coincide with
your heartbeat could signify a serious condition. Most commonly, such
pulsations are due to abnormalities of the bony orbits surrounding your eyes,
anomalies of the blood vessels supplying the eyes, or possibly even a tumor
behind the eye. When your blood pressure jumps during a doctor visit (or any
other stressful event), this could "unmask" a problem that otherwise
isn't obvious. While your pulsations might not be associated with an underlying
problem, it would be prudent to see an ophthalmologist. He/she will carefully
examine the vessels in your eyes, and you may be sent for a MRI of your
orbit(s). Good luck!
