IIR-2023-1274 (Dry Eye from Sjogren's Syndrome) - Clinical Trial

We are doing this study to learn more about how different factors affect people with two types of dry eye conditions: Sjögren's dry eye (SjD) and non-Sjögren's dry eye. Specifically, we want to know how neurotrophic keratitis (a condition where the cornea loses sensation) versus the severity of tear film and eye surface issues impact the structure and function of the cornea (the clear front part of the eye). We also want to find out if having dry eyes leads to less feeling in the cornea, and if this reduced feeling is linked to eye pain or pain in other parts of the body.
