This IOP change in the GH group is similar to the findings in our previously reported experiment [34,35] using the same glaucoma filtration surgery model and DDS, whereas IOP in the GH-TGF-β group was lower at 4-weeks postoperative, thus suggesting that anti-TGF-β antibody released from GH maintains IOP reduction. Here, TGFB1 is linked to glaucoma.
