I have recently acquired severe dry eyes syndrome and have begun having several symptoms that are probably related to that... halos, starbursts, glare, foreign body sensation and irritation. I've done a few tests with my opthamologist including an OCT but I don't think it will show anything since the dilation drops simply multiplies the problems I'm having. I've done some reading, and have some effects of Sjogren's Syndrome: dry eyes, dry mouth, throat feels swollen, constantly chapped lips. In fact, I never thought anything of my constant need to reapply chapstick every few hours for months until now! I've also had some acid reflux that comes and goes over the last few months. I discovered in the summer that I have an unusually low IGA, meaning my salivary gland production is very low. Could a low IGA cause Sjogren's Syndrome? Am I just being paranoid or does this seem likely?
