TGFB1 and glaucoma: Graft- or device-specific metrics like goblet cell reconstitution in MMG, epithelial phenotype stability in COMET, limbal niche restoration in SLET, tear secretion rate per unit area and salivary composition vs. basal tear proteome in MSGT, AMT’s anti-fibrotic effect via TGF-β pathway readouts, and keratoprosthesis retention with glaucoma structural/functional surveillance—are not uniformly measured.
