Thanks for your interesting question.
I assume you are followed on regular basis for your high blood pressure, and that you are taking your medication as prescribed.
Most people with high blood pressure have no symptoms, which is why it is known as the "silent killer." However, in extreme cases, people will have symptoms of headache, vision changes, nose bleeds, and others. A pulsating sensation in the eyes is not something I would expect unless the pressure was extremely high. Another possible cause that come to mind and should be checked for by your doctor include Thyroid disease which can cause a faster pulse rate, with a more dynamic pulse that patients can sense and sometimes even hear. They note these findings while falling asleep, when the room is quiet of other noises or distractions. If your pule pressure is high (the difference between your systolic reading and the diastolic reading), this can cause a very dynamic pulse that could be sensed by the patient. In severe cases, a patients head will actually bob to a small degree. Cause for high pulse pressure include heart valve problems, which your doctor can also check you for. In some cases, an echocardiogram is ordered to check the valves out, as well as other heart structures.
You need to make an appointment with your physician to have your pressure checked, as well as looking for the above possibilities. Should your doctor not find any cause for your compaint, ask him about seeing an opthalmologist for an evaluation.
