I had an Eeg of my eyes today. I closed my eyes for resting them befor the test began. Then with the right eye covered, I opened my eyes, focused at a red dot while a black and white checker-board flashed around the screen. I would blink periodically, but could focus pretty well. The dot appeared to get larger and smaller at times. And the checker-boards appeared to come at me in 3-dpD towards the end of the test. Then the same procedures were taken to cover my left eye was covered to take the test. This time, I began to get very frustrated. The though it was the very same test administered, the squares from the checker-board were covering most of the dot. While trying to focus on the dot, it was very hard to find it and focus on it. It was tiring, draining, frustrating. The squares just seemed to jump all over the place. One reason for the test is I have so many symptoms of MS.
