Yu-Wai-Man C, et al. - Researchers undertook a comparative inspection of the clinical phenotype of patients with conjunctival fibrosis after glaucoma surgery, with candidate gene expression tissue biomarkers of fibrosis. The inference drawn was that IL6 and PRG4 reflected 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 scrutiny was necessitated.
