Summary
The purpose of this study is to evaluate acute tear production produced by the intranasal tear neurostimulator in participants with Sjögrens syndrome and aqueous tear deficiency. Our primary goal is to evaluate whether Sjögrens patients respond to this intervention and whether there is a baseline tear production level below which these patients do not respond.
