TGFB1 and glaucoma: Similar to the elevated AH concentrations of the TGF-β isoforms, a previous study demonstrated that the intensities of the anti-TGF-β-antibody-labelled conjunctival cells were significantly higher in patients with glaucoma (35.21% ± 14.12%) as compared with control patients (14.96% ± 6.34%) (p = 0.001) [60].
