I have recently decided that I have a mild (?) case of connective tissue disorder. I'd never heard of it, but somehow I ran across a list of symptoms and had a shockingly large number of them, although all in rather minor form. I now see that some people list (some) glaucoma sufferers as having this syndrome. I am myopic (my parents were not), which is related to CTD and glaucoma.
You can easily look it up. One site with a list of "symptoms" is this one: http://www.ctds.info/
