I had a brain aneurism burst bak in 2009 an it was located In the back left side if my head. When it busted it caused me to lose my perifial vision in the top right of my right eye an they said it can't be cut out or I would be blind the rest of my life so they decided to do radiation sugery. Well I went back an had an angiogram done in November of 2012 an they said the aneurism was completely gone all I had left was scare tissue. Well now I have been sick the past week an ever since I've been sick my vision has been messing up. Do you have any idea what could be wrong?

When you're sick your body does a lot of funky stuff to fight off the infection. A lot of that can affect blood pressure and blood flow. Scar tissue, and I am not sure about cerebral scars, is not as pliable as normal tissue.

This is concerning and I would see your doctor about it. It could be indicative of more severe problems.
