Yu-Wai-Man C, et al. - This trial executed a comparative study of the clinical phenotype of patients with conjunctival fibrosis following glaucoma surgery with the candidate gene expression tissue biomarkers of fibrosis. The results reported that IL6 and PRG4 served as potential novel tissue biomarkers of disease severity and prognosis in conjunctival fibrosis after glaucoma surgery. In order to validate the effect of these potential biomarkers of fibrosis, further exploration was necessitated.
