So looking up stuff about abdominal pain/liver – I come across hemacromatosis – then it turns out that links to Fleischer Rings in the eye – which are associated with Keratoconus. So digging more on that I come across this pdf, which has this info:
Although CN6 palsy is most common throughout the lifespan of all patients, in patients with EDS, exotropia, possibly due to CN3, is the most common palsy. Esotropia is going to present most often with fusion and near, and uncrossed diplopia at far, or a divergence insufficiency. Cranial nerve 3 trouble, even partial CN3 which will leave the lid not involved, and perhaps have such a small hypotropia that you won’t see it, with no pupil involvement, will generally cause more problems at near than at far. The reason being that it’s harder to fuse the images at near, so instead of getting a DI, as you would with a CN6 palsy and diplopia at far, you will get a CI with diplopia at near with problems with the medial rectus, which is innervated by CN3.James Kundart OD, MEd, FAAO, FCOVD-A
It’s much easier to find info and connections than it was a decade ago, partially due to people sharing information online and a good part towards Diana Driscoll who James mentions elsewhere in the above pdf. I found her when she was still just writing for her blog Pretty Ill
I have EDS, I believe my kiddo does too, and we recently finished his CI (convergence insufficiency) therapy. And another immediate family member has double vision. Eventually I’ll test myself for CI too. I definitely think it’s a possibility, because when I tried doing the CI exercises with the kiddo, they were difficult and painful for me also.
My spouse has hemacromatosis in his family and keratoconus himself, which is why I even went down that rabbit hole and found these connections.
EDS is NOT a connective tissue disorder. It is a COLLAGEN disorder, connective tissue just being one of the most obvious traits/challenges since it is the main structural component of connective tissue. Collagen is present in pretty much every body system (I actually couldn’t find one that had none):
Collagen is a protein. In fact, it’s the most abundant protein in your body. There are at least 16 types, but the most common are Type I, Type II, Type III and Type IV.Dr. Liz Liotta
Collagen is made up of strong and stable fibers that work like glue to hold things in your body together and strengthen them. You can find collagen everywhere, from head to toe, including hair, muscles, bones, tendons, ligaments, organs and all over — in your skin. Collagen also creates elasticity that allows us to move, bend and stretch.
So it can cause all sorts of problems all over the place that get written off as unknown causes or lumped into a syndrome (a syndrome is just a collection of symptoms that appear together – which they may or may not know the cause of).
