Have any of you all had vision affected during a CH cycle but not during an attack? I do not know if it is coincidental or not (and I suspect it is not), but during my month-long cycle that occurred in February, I felt at times that I had slight double vision. One night it was extreme. I was playing tennis and I saw two balls coming at me when in reality it was only one. After two sets I had to stop playing. I went to an optometrist and she said the muscles in my eyes weren't keeping my eyeballs perfectly aligned. But now that the CH cycle is over I don't have that double vision anymore, either slight or severe. I have been having episodic CHs since 1979, and this cycle was a strange one in several ways, including possibly the vision element. Thanks. Andrew

Hi Andrew, your post describes what happens to me as well. Whenever my vision in my CH eye (left) tanks then I know a CH is coming. I also start stumbling as if I am drunk; and I do not drink. Things improve in those two areas once the CH hits. But then I get the CH to deal with for Lord knows how long.
