re my post this thread 13 February, I had the tests today. Took a little over two hours.
Some of them were weird.
The clinician put a camera on my head to monitor my eyes. There was a small sticker on the wall about 2 feet from me. I had to keep my eyes on the sticker while he yanked my head left. right. up and down, while he monitored my eye movement. Then I had to hold my head still while following a light spot jumping around all over by just moving my eyes. Then I moved into a soundproof booth to do the hearing tests normally done by audiologists. This was to determine if I was a suitable candidate for Cochlear Implants.
Then I moved into another room where I had to lie on a bed. He rubbed my earlobes and forehead lightly with sandpaper and attached stickers and leads. He placed earphones in my ears, and he played a tapping sound; like repeatedly tapping on a cardboard box. At first it sounded like an approaching helicopter, but settled down like an idling motorbike. I had to look left, right, and roll my eyes as far up as possible, 5 minutes in each position. He took out the eyephones and placed a metal gizmo behind my ears and repeated the tapping so that I could feel it like he was tapping behind my ears. Then he repeated the whole thing with the sandpapering, stickers and leads on my neck, chest and just under my eyes.
Finally, we moved to a third room, where I sat on the foot of a bed in front of a TV screen about 48 in size. He put a bulky pair of glasses, like a virtual reality headset, which contained a camera. It's scary looking at your eye filling a large TV screen. Then he played a yellow dot on the screen and I had to follow it without moving my head. Then he placed a cover over the lens so it was totally dark, and the displayed a small spot of light in the headset. I had to look a the position of the light. He turned it off and I had to keep looking at the spot without closing my eyes. It's hard to know if your eyes are open or closed when it is totally dark. Then I had to lie on the bed blindfolded while he blew very warm air into each ear to see if it made me feel the room was spinning.
All these tests were recorded in graphs on the computer. He will email the results to my doctor with a copy to me by mid next week.
