    Temporary circular blurry vision in one eye.
    DawnSFreeman posted:
    Yesterday while shopping I experienced blurred vision. Trying to read price tags I realized I couldn't see clearly out of my right eye. No pain involved. I noticed a arch shape on the outer right edge, like part of a circle. It only lasted for about ten minutes. I have high blood pressure, being maintained with medication. Should I be concerned?
    Alan M Kozarsky, MD responded:
    Ms. Freeman,

    Almost any visual disturbance that occurs suddenly and disappears completely after ten minutes is being caused by a circulation issue.

    Circulation disturbances affecting vision can be ocular migraines (with or without a headache) or even be a transient ischemic attack (TIA).

    This is certainly something you want to discuss with your primary care physician, the one prescribing your blood pressure medication. The level of suspicion for anything more serious than a migraine type even depends on your age and general health.

    Dear Dr Kozarsky,

    I have had the similar condition where I had a blurred spot in an arch shape in my visual field, but mine also contains flashing lights and pushes out toward the edge of my vision before going away. It takes mine about 30 to 40 minutes to go away sometimes. I don't have high blood pressure that I know of, but what do you make of this condition. I don't get a headache afterward either. I see the eye doctor once a year and get my eyes dialated and have told him about this phenomenon. I can tell you that I am a coffee drinker and sometimes will drink coffee through the day without eating or drinking water, but not sure if it relates. What could cause this?

    Hi Sjeffer,

    Dr. Kozarsky mentioned ocular migraines (with or without the actual headache pain). Have you discussed that possibility with your eye doctor?

    I used to experience blurred vision. I don't any longer after I had a PFO closure device fitted in my heart following a stroke. Coincidence?
