One more note - sometimes a systemic medication like topamax or prednisone can make vision terribly blurry. Look into a possible medication side effect.

I'm unclear what is going on here. The exam wouldn't really give you a new disease or diagnosis so obviously something is going on. To set you mind at ease, I suggest seeing another ophthalmologist so see what is going on, because I sense that you have lost confidence in the last one. Maybe you have diabetes or glaucoma or an allergic reaction to one of the drops at the office. Sorry, I can;t offer much more. Somewhat vague symptoms, unclear cause. Don't be discouraged, if no answers, ask another doctor.
