I also have dry eyes along with other eyes issues. I was told by my opthamologist whom is also a retina specialist that in those with EDS dry eyes were common. If you can try to get to get to a teaching hospital or major medical center to see a geneticist whom would be best bet for diagnosis of EDS. With all the other evidence you have this will be very helpful. GL if finding out what is going on so that you can find out specifically what collegan and connective disease you may have.
I do not have glaucoma.
My dry eyes are still considered mild so I use water washes as need be and close and rest eyes when can.
