Symptoms: raising of one eyelid during chewing or opening the jaw. Thanks to all for not saying anything. Although I notice this from time to time now, I also recall my mom describing this happening when I was breast feeding (ok settle down, over 23 years ago).
So my inner nerd/doctor kicks in. Immediately, I think trigeminal nerve (Cranial nerve V3), that innervates the pterygoid muscle, or... one of your chewing muscles. Also, the Occulomotor nerve (Cranial III) innervates levator palpabrae superioris, the muscle that levatates the eye lid. Bet you didn't know you could levatate could you? Okay wow, I know, enough of that. This is what our brains sound like, we just have to learn to shut the nerd center off so we don't sound like whackjobs to normal people. This is my blog, so deal with it. haha.
I expected that these two nerves are somehow linked together. With some light wikipedia searching, I quickly come upon the Marcus-Gunn Phenomenon. BINGO. I am so Smrt. S-M-R-T.
A rare congenital defect, seen in 5% of children with lazy eye. I am happy to announce that, although this "phenomenon" usually presents along with other defects like lazy eye, cross-eyes, drop-lid, etc, I don't have any of those cool defects that would make me "special". All I have is just the Marcus-Gunn part. Woo!! beat the curve!
Cool. I guess that just makes me a little more rare, and... and susceptible to laughter while I chew. Meh, gotta pay the price to be rare these days.
