Brief Summary
The specific aims of the the investigators studies are as follows:
- To collect the tear samples from patients with different ocular surface disorders, including SLK, conjunctivochalasis, and keratoconjunctivitis sicca (KCS).
- To evaluate the differential expression of tear cytokines and pH values between different ocular surface disorders.
- To collect the surgical conjunctival specimens from the patients with SLK and conjunctivochalasis.
- To evaluate the factors inducing mast cell migration and how mast cell is activated in SLK via surgical specimens and cultivated fibroblast.
