TGFB2 and glaucoma: Aqueous humor has been implicated in failure of the filtering surgery due to presence of certain factors that stimulate fibrosis in the subconjunctival space.18 Aqueous humor from glaucoma eyes has been reported to support growth of subconjunctival fibroblasts in tissue culture19 and has been found to have increased levels of TGF-β2.20 In our study, reduction in capsular porosity was seen after exposure to BSS, demonstrating that there are reasons other than aqueous cytokines, for capsule porosity to fail.
