pupil size and highblood pressure

I went to do the doctor today becuase I have been having really weird symptoms. My blood pressure was sky high, so they put me on medicine. During the exam she said my pupils were different sizes and she was slightly concerned. Of course I googled it and all I see is brain tumor. Can high blood pressure cause pupil sizes to be different?

Anisocoria - Anisocoria is unequal pupil size.

Common Causes

The use of eyedrops are a common cause of a harmless change in pupil size. Other medicines that get in the eyes, including medicine from asthma inhalers, can change pupil size.

Other causes of unequal pupil sizes may include:

    Aneurysm
    Bleeding inside the skull caused by head injury
    Brain tumor or abscess
    Excess pressure in one eye caused by glaucoma
    Infection of membranes around the brain caused by meningitis or encephalitis
    Migraine headache
    Seizure (pupil size difference may remain long after seizure is over)
    Tumor, mass, or lymph node in the upper chest or lymph node causing pressure on a nerve may cause decreased sweating, a small pupil, or drooping eyelid all on the affected side (Horner syndrome)

It seems possible that the medication you were given could have blocked the effects of your catecholamines reducing your blood pressure but also inhibiting your iris response.  

I' am not an eye specialist; so I hope someone more qualified will be able to give you a proper answer.

High blood pressure would not likely cause unequal pupils without a major complication like stroke.  You do need to see an ophthalmologist Eye MD. When you go in 1. take 5-6 good facial pictures  taken over the last 10 years that clearly show your pupil size. 2. Do not let the technicians put any drops in your eye til the eye MD looks at your pupils.
